The bank/agency work you're comparing it to
Set this to roughly the same volume of work as your substantive post's hours, for a fair comparison — or lower, if you're only picking up occasional shifts. Want just the pure day-rate-vs-PAYE-bank comparison for this figure? Use the Locum & Bank Rate Calculator instead.
Left unticked by default: bank/agency pension participation varies a lot and is often intermittent — not a universal rule, but a general pattern. Some bank shifts and some agency roles genuinely do offer pension access; tick this if that applies to your situation.
Total annual value, substantive vs bank/agency
Substantive post
£69,793
Bank/agency work
£43,825
The substantive post is worth £25,968 more a year on this basis.
"Total annual value" adds net take-home pay to the annualised value of paid annual leave, paid sick leave and one year's NHS Pension accrual — on the same total-reward basis the NHS's own Total Reward Statements use. It is not extra cash on top of your payslip; see "How this figure is built" below.
1. Take-home pay, for the actual hours/days worked
Bank/agency gross annualises £57,357 from your day rate × days/week × 52.143 weeks — the same annualisation FrontlinePay uses everywhere else on the site.
2. Paid annual leave — a substantive post keeps paying you
5 to 10 years' service: 37 days/year, worth £4,909
Valued at your substantive hourly rate. Bank/agency income is generally earned only for days you actually work — see the Annual Leave Calculator for the entitlement on its own.
3. Paid sick leave — the value of the safety net
After completing five years of service: up to 52.14 weeks, worth £25,943 if fully used
This is the full Section 14 entitlement's value if you ever needed all of it — not a prediction you'll use it. See the Sick Pay Calculator to model an actual period of absence.
4. NHS Pension accrual, one scheme year
Substantive post
+£640.59/yr pension → £12,812
Bank/agency
Not modelled (unticked above)
The £/yr pension figure is capitalised at the standard 20:1 factor used elsewhere on FrontlinePay (the same convention behind the McCloud comparison and commutation tools), purely so it can be added into a single £ total alongside take-home pay — it isn't a cash lump sum you can access now.
Short answer
A substantive NHS post's headline salary is only part of what it pays you. On top of take-home pay, it also gives you paid annual leave, paid sick leave entitlement and continuous NHS Pension Scheme membership — all of which keep paying out (or keep accruing) whether or not a given week is a working week. Bank and agency work is generally paid only for days actually worked, and pension access varies and is often intermittent. This calculator adds the annualised value of leave, sick pay and one year's pension accrual to take-home pay, for both sides, so you can see the fuller "total annual value" — not just which day rate looks bigger. It deliberately doesn't (and can't) put a number on job security and guaranteed hours, which is a real factor of its own — see the note further down the page.
Why a day-rate comparison alone doesn't tell the whole story
It's easy to compare NHS bank or agency work to a substantive post by lining up two numbers: your contracted salary against a day rate multiplied by the days you'd realistically pick up. On that measure alone, bank and agency work often looks like the better deal — day rates are usually set higher than the pro-rated equivalent of a substantive salary, precisely because they're meant to compensate for everything that comparison leaves out. The trouble is that "everything the comparison leaves out" is often worth more than people expect, and it's very hard to see without deliberately calculating it.
A substantive post's Agenda for Change (or equivalent) terms and conditions bundle in three things that don't show up in a simple hourly or daily rate: paid annual leave that scales with your length of service, paid sick leave under Section 14 of the NHS Terms and Conditions Handbook, and continuous membership of the NHS Pension Scheme, which keeps accruing whether your year was quiet or eventful. None of these are unique to the NHS — most permanent employment includes some version of them — but the NHS's specific entitlements are unusually well documented and unusually generous by UK standards, which makes the comparison against bank/agency work particularly worth running properly rather than skipping straight to the day rate.
Worked example: Band 5, Point 2, 5 years' service vs a £250 day rate
Take a full-time Band 5 nurse on the real 2026/27 pay scale, Point 2 (£34,592 a year), with 5 years' continuous NHS service, weighing up their substantive post against picking up agency work instead at a £250 day rate, 5 days a week — roughly the same volume of work. Here's how the two compare once everything beyond take-home pay is counted in.
| Component | Substantive post | Bank/agency (5 days/wk @ £250) |
|---|---|---|
| Annualised gross | £34,592 | £65,179 |
| Net take-home pay | £26,129 | £48,361 |
| Value of paid annual leave (37 days) | +£4,909 | £0 (not modelled — general pattern) |
| Value of full sick pay entitlement (52.14 weeks) | +£25,943 | £0 (not modelled — general pattern) |
| One year's NHS Pension accrual, capitalised | +£12,812 | £0 (unticked by default) |
| Total annual value | £69,793 | £48,361 |
On take-home pay alone, the agency scenario in this example comes out higher than the substantive post by £22,232.14 a year — but once the value of paid leave, paid sick leave and pension accrual are added in, the substantive post's total annual value comes out £21,432 ahead overall. Change any of the pension checkboxes in the calculator above and watch how much of that gap is coming from pension continuity alone — for many comparisons, it's the single biggest factor.
What substantive employment actually protects that bank/agency work generally doesn't
Paid annual leave that scales with your service
Under Section 13 of the NHS Terms and Conditions Handbook, full-time AfC staff build up more annual leave the longer they stay — starting at 27 days, rising to 29 days after 5 years' service, and 33 days after 10 years, plus bank holidays on top. That leave is paid at your normal rate regardless of whether you take it as a single block or spread across the year. A day-rate arrangement, by contrast, generally pays you only for the days you work — so taking the equivalent time off means forgoing that income entirely, unless your specific engagement says otherwise. The longer you've been in the NHS, the more this specific benefit is worth, which is part of why "years of service" is one of only two inputs (alongside salary) this calculator asks for on the substantive side.
Paid sick leave that doesn't reset overnight
Section 14 of the same Handbook sets out a scale of sick pay that also grows with service — from one month's full pay and two months' half pay in your first year, up to six months' full pay and six months' half pay once you've completed five years. It's genuinely one of the more generous statutory-adjacent sick pay regimes in UK employment. Bank and agency work carries no equivalent scale in the same way — you're generally reliant on Statutory Sick Pay at most, and whether even that applies depends on your specific employment status with the agency or bank. This calculator values the FULL entitlement at your tier — not a prediction that you'll use it, but a way of seeing what that safety net alone is worth if you ever needed to draw on it.
Pension continuity, not just pension existence
The NHS Pension Scheme's 2015 CARE section banks roughly 1/54th of your pensionable pay every scheme year, every year, for as long as you're an active, contributing member. The compounding value of that continuing every single year of a career — as modelled on FrontlinePay's own NHS Pension Calculator — is substantial. The risk with bank and agency work isn't necessarily that pension access is unavailable (some arrangements do offer it), it's that participation tends to be less continuous: a shift here, an assignment there, gaps between engagements, and — as the standalone Locum & Bank Rate Calculator already explains — umbrella company workers in particular are generally not enrolled in the NHS Pension Scheme at all. A single missed or interrupted year doesn't sound like much on its own, but stacked up over a career, inconsistent pension membership can leave a meaningfully smaller pot than someone who simply stayed enrolled the whole way through.
Redundancy protection and continuity of employment
A substantive post also carries contractual protections that day-rate work generally doesn't — most notably, eligibility for NHS contractual redundancy pay under Section 16 of the Handbook after two years' qualifying service, worked out at FrontlinePay's own Redundancy Pay Calculator, plus statutory notice periods and the general employment protections (unfair dismissal rights, family leave entitlements, and so on) that come with continuous employment. Bank and agency engagements are typically far more flexible for both sides precisely because they don't carry the same level of mutual commitment — which cuts both ways: it's part of why they can pay a higher day rate, and part of why they don't carry these protections.
What "general pattern, not universal rule" means here
You'll see that phrase more than once on this page, deliberately. NHS bank and agency work isn't one single thing — a regular shift on your own trust's staff bank, an occasional agency booking through a third party, and a long-running locum arrangement can all look very different in terms of what pension access, notice, and continuity they actually carry. Rather than invent a precise participation percentage or a specific "X% of agency workers don't get sick pay" statistic — numbers that don't actually exist in any reliable published source — this calculator describes the general, well-established pattern honestly: substantive posts carry consistent, scaled Agenda for Change entitlements; bank and agency work varies, and is often less continuous. Use the checkboxes in the calculator to model your own actual situation rather than relying on the defaults if you know your circumstances differ.
⚠The thing no calculator can put a number on
Everything on this page can be reduced to a number — take-home pay, leave value, sick pay value, pension accrual. Income certainty can't be, and we haven't tried to fake one. A substantive post gives you a guaranteed weekly income regardless of demand; bank and agency work, even at a much higher headline rate, depends on shifts genuinely being available and offered to you, which varies enormously by specialty, region, time of year and your trust's or agency's own booking patterns. For some people that variability is a manageable trade-off for flexibility and a higher rate; for others, it's the single biggest risk in the whole comparison. This calculator can tell you how big the OTHER factors are — it can't and won't tell you how much income certainty is worth to you personally, because that's a judgement only you can make.
The same honesty applies to bank/agency terms themselves: they genuinely vary. Some bank shifts are pensionable; some agency roles do offer paid leave or a workplace pension; some don't. Always check your own specific engagement's actual written terms rather than assuming either this calculator's general pattern or its opposite applies to your situation.
How this calculator is built
Nothing here reinvents FrontlinePay's existing tax, pay, leave, sick pay or pension logic. Take-home pay on both sides runs through the same income tax, National Insurance, NHS Pension Scheme and student loan engine used by the main NHS Pay Calculator. Annual leave uses the same AfC Section 13 tiers as the standalone Annual Leave Calculator. Sick pay uses the same Section 14 tiers, sourced directly from the NHS Terms and Conditions Handbook, as the standalone Sick Pay Calculator. And the pension figure uses the same 2015 CARE accrual mechanics as the NHS Pension Calculator, capitalised with the same 20:1 valuation factor used across FrontlinePay's other pension tools. The only new logic this page introduces is how those five already-verified pieces are combined into one side-by-side comparison.
Why this comparison holds up
- ✓ Composes five already-verified FrontlinePay engines — pay, tax/NI/pension, sick pay, annual leave and CARE pension accrual — rather than inventing new logic for this tool.
- ✓ Section 14 sick pay and AfC Section 13 annual leave use the exact same sourced tiers as the standalone Sick Pay and Annual Leave calculators, not a simplified re-guess.
- ✓ No fabricated statistic for bank/agency pension participation or sick pay coverage — described honestly as a general, hedged pattern with checkboxes to model your own actual arrangement.
- ✓ Pension accrual is capitalised using the same 20:1 factor used across every other FrontlinePay pension tool, not a bespoke multiplier invented for this page.
- ✓ Deliberately doesn't score or quantify income certainty and guaranteed hours — a real factor no honest calculator can put a single number on.
- ✓ Runs entirely in your browser — your salary, day rate and service history are never sent to a server or stored.
Frequently asked questions
What does "total annual value" actually mean, and why doesn't it match my payslip? +
It's not meant to match your payslip — your payslip only shows cash. "Total annual value" adds your net take-home pay to the annualised value of paid annual leave, paid sick leave entitlement, and one year's NHS Pension accrual, using the same total-reward-statement logic the NHS itself uses when it sends members a Total Reward Statement each year. The leave and sick pay figures aren't extra money on top of your salary — your salary already pays you whether or not a given week is a working week, a leave week, or (within entitlement) a sick week. They're included here so the comparison against bank/agency work, which is generally paid only for days actually worked, is fair and complete rather than just comparing headline day rates.
Isn't this the same as the Locum & Bank Rate Calculator? +
No — they answer different questions. The Locum & Bank Rate Calculator compares PAYE staff bank pay against umbrella company pay for the SAME day rate: pure pay-rate mechanics, plus an IR35 explainer. This calculator instead compares a substantive (permanent) post against bank/agency work on the fuller picture beyond the headline rate — continuity of paid leave, paid sick leave and pension, not just how a given day rate gets taxed. If you want the detailed umbrella-margin-fee, IR35-aware comparison, use the Locum & Bank Rate Calculator; use this one for the bigger "is it actually worth it" question.
Why count paid annual leave and sick pay if my salary already includes them? +
Because the alternative you're comparing against generally doesn't include them. A substantive post's salary is fixed for the year regardless of how many of your contracted days are spent at work, on leave, or (within entitlement) off sick. Bank and agency income, by contrast, is generally earned only for days actually worked — take the same fortnight off, and a day-rate worker typically earns nothing for it unless their specific arrangement says otherwise. Showing the value of that continuity as a distinct line lets you see exactly how much of the total gap between the two options comes from income security rather than the headline rate.
How is the pension figure worked out, and why multiplied by 20? +
The £/year figure is one scheme year's 2015 CARE Scheme accrual — pensionable pay ÷ 54, the same accrual rate used by FrontlinePay's NHS Pension Calculator. Because that figure is an annual pension INCOME, not a cash sum, it can't be added directly to a take-home-pay total in any meaningful way. So we capitalise it — multiply it by 20 — using the same standard valuation factor already used elsewhere on FrontlinePay (the McCloud remedy comparison and the commutation lump sum optimiser), which is also the convention HMRC itself uses when valuing pension income for lump sum allowance purposes. It's a standard way of expressing "what is this year's pension promise roughly worth today", not a cash sum you could withdraw.
Why is bank/agency pension access switched off by default — are you saying agency workers never get a pension? +
No — and we've deliberately avoided inventing a precise participation statistic, because there isn't a single reliable figure that applies to every bank shift and every agency engagement. The general, honestly-hedged pattern is that a substantive post gives you consistent, continuous NHS Pension Scheme membership, while bank and agency pension participation varies a lot and is often more intermittent — some ad hoc bank shifts are pensionable, some agency roles do offer a workplace pension, and plenty don't. The checkbox defaults to off to reflect that general pattern, but it's there specifically so you can tick it and model your own actual arrangement if it does include one.
What about job security and guaranteed hours — why isn't that in the total? +
Because no honest calculator can put a single number on it. A substantive post gives you a guaranteed, contracted income every week regardless of demand; bank and agency work, even at a higher headline rate, generally depends on shifts being available and offered to you. That's a genuinely significant factor in deciding between the two — arguably as significant as anything this tool does calculate — but it varies enormously by specialty, trust, local demand and your own circumstances, and turning it into a fabricated "certainty score" would just be a made-up number dressed up as data. This calculator deliberately leaves it out of the total and flags it prominently instead, so you weigh it yourself rather than have a false precision talk you out of thinking about it.
Can I just plug in my actual day rate and trust the answer completely? +
Treat it as a genuinely useful planning comparison, not a guaranteed prediction. The tax, pension and entitlement mechanics are the real, sourced NHS rules — the same engines used across FrontlinePay's other calculators — but your own bank/agency terms, exact working pattern, and how consistently shifts are actually available to you will all vary from the averages this tool assumes. Use it to see the SHAPE of the comparison and roughly how large the non-headline-rate factors are, then check your own specific offer's terms before deciding anything.
What if my bank or agency work does include paid leave or sick pay? +
Then the real gap between your two options is smaller than this calculator shows, because it deliberately doesn't model any leave or sick pay value on the bank/agency side — that's the honest default given how much these terms vary. If you know your specific bank or agency arrangement includes paid leave, holiday pay rolled into your rate, or sick pay, factor that in yourself when reading the comparison, or check your engagement's actual written terms rather than assuming either the presence or the absence of these benefits.
Is this financial or career advice? +
No. It's a planning tool that applies the real, sourced NHS Terms and Conditions and NHS Pension Scheme rules to numbers you provide, to help you see a fuller picture than a day-rate comparison alone. Whether to leave a substantive post, reduce your hours, or move into locum/bank/agency work full time is a significant personal and financial decision that depends on things this tool can't see — your specific specialty's demand, your family circumstances, your risk tolerance, and your long-term career plans. Speak to your union, a financial adviser, or NHS Pensions directly before making a decision this consequential.
Does this work the same way for doctors, AHPs and other roles, not just nurses on Agenda for Change? +
The mechanics apply across every AfC role — the Section 14 sick pay tiers and Section 13 annual leave tiers used here apply Handbook-wide, not just to nursing. If you're not on an Agenda for Change band (for example, doctors and dentists on their own separate pay structure), use "Enter a custom salary" and enter your actual pay directly — the sick pay, annual leave and pension mechanics behind the calculation are the same either way, since they're driven by your years of service and your actual salary, not by which specific pay structure set that salary.
