NHS Income Protection Gap Calculator

Enter your pay, service and outgoings to see your NHS sick pay month by month, the point your income falls below what you need, and how long your savings would last. Free, private and worked out in your browser.

Start with the basics: see your NHS sick pay entitlement first, then use this to judge whether a gap needs covering.

Short answer

NHS sick pay on Agenda for Change terms runs from 1 month's full pay plus 2 months' half pay in your first year to 6 months' full pay plus 6 months' half pay after five years. Statutory Sick Pay (£123 a week, for up to 28 weeks) is added to half pay but never takes you above full pay. Once the scale is used up, NHS sick pay stops. The gap is the difference between what you would then receive and what you need to pay your bills. This calculator works out that gap for your own figures.

Assumptions

Statutory Sick Pay is £123 a week (or 80% of your normal pay if lower) for up to 28 weeks, from gov.uk, checked 7 October 2026. It is added on top of half pay but never takes you above full pay (Handbook 14.6). Your absence is assumed to start today with your service tier as entered. Tax and pension are estimated, so treat every figure as a planning estimate.

What your numbers show

Your income first falls below your outgoings in month 7. Your savings would run out in month 14, and the gap after that would be unfunded.

After completing five years of service. Normal take-home about £2,325 a month, so your outgoings are about 82% of it.

Facts to have ready if you ever price a policy

  • Your NHS sick pay on these figures lasts about 52 weeks. The guide on this site explains why some people choose a policy waiting period that lines up with that.
  • The largest monthly shortfall here is £1,900. That is your outgoings less other income, not a recommended benefit amount.
  • Policies are individually underwritten, so cost, waiting period and the definition of being unable to work vary. Compare through a whole-of-market broker or an independent financial adviser.

FrontlinePay is not a licensed financial adviser and does not recommend or sell any insurer or policy.

Not modelled

NHS Injury Allowance for work-related injury or illness (Section 22), reinstatement of half pay after 12 months of continuous absence (14.10), employer discretion to extend sick pay (14.13), ill-health retirement, and benefits such as Universal Credit or New Style ESA. Any of these could shorten the gap. Enter benefits you expect under "Other monthly income" if you want them reflected, after checking eligibility on gov.uk.

Next step: check what the Handbook pays on a specific absence with the NHS Sick Pay Calculator. See your NHS sick pay entitlement first, then decide whether a gap needs covering.

NHS sick pay by length of service

Paragraph 14.2 of the NHS Terms and Conditions of Service Handbook sets the "scale of allowances" for sick pay. The wording is the same in the England, Wales and Scotland and Northern Ireland editions. This is the table the calculator is built on, and it is also used by the NHS Sick Pay Calculator.

Length of serviceFull payHalf payTotal (approx. weeks)
During your first year of service 1 month 2 months 3 months (13 weeks)
During your second year of service 2 months 2 months 4 months (17 weeks)
During your third year of service 4 months 4 months 8 months (35 weeks)
During your fourth and fifth years of service 5 months 5 months 10 months (43 weeks)
After completing five years of service 6 months 6 months 12 months (52 weeks)

Any paid sick pay you took in the 12 months before a new absence starts is deducted from the entitlement (paragraph 14.7), so repeat absences can have less than the full scale. The first field under "Your details" that says paid sick weeks in the last 12 months handles this. For a detailed look at one planned absence, including that deduction week by week, use the NHS Sick Pay Calculator, and for the policy itself read NHS sick pay policy explained.

Do you get Statutory Sick Pay on top of NHS half pay?

Yes, for part of the time. The Handbook says full pay is inclusive of statutory benefits and that Statutory Sick Pay added to half pay must not exceed full pay (paragraph 14.6). So while you are on half pay and still have SSP weeks left, you receive half pay plus SSP, topped up no higher than your normal pay. SSP is £123 a week (or 80% of normal weekly earnings if lower) for up to 28 weeks, according to gov.uk, checked 7 October 2026. The 28 weeks are counted from the start of the absence, not from when half pay begins, so the top-up is short for people with long full-pay periods.

Take someone with six years' service. Full pay lasts about 26 weeks. Half pay then starts, and only about two SSP weeks remain, so they receive about £1,709 a month for those two weeks, then £1,351 a month on half pay alone. Someone in their first year, whose one month of full pay and two months of half pay all fall inside the first 28 weeks, gets SSP on top of every week of half pay. The calculator handles both cases automatically.

Worked example: six years' service on £38,000

These figures come from the same engine as the calculator above. Salary £38,000, six years' continuous service, in the NHS Pension Scheme, England tax, no sick pay in the last 12 months, essential outgoings of £1,900 a month, savings of £3,000 and no other income.

PhaseWeeksTake-home a month
Full pay 0 to 26 £2,325
Half pay plus SSP 26 to 28 £1,709
Half pay alone 28 to 52 £1,351
No NHS or statutory sick payFrom week 52£0

Full pay covers the £1,900 of outgoings comfortably, so there is no gap in the first six months. On half pay the income drops below outgoings, with a shortfall of about £549 a month that the savings cover for a while. After about month 12 the NHS pays nothing, the full £1,900 is uncovered, and the £3,000 of savings runs out in month 14. In the first 12 months the total shortfall is £3,136. This is why the gap that matters is not the early months but the period after contractual sick pay ends.

Worked example: in your second year of service

With £32,000 salary, one and a half years' service (two months' full pay, two months' half pay), £1,700 of outgoings and £1,000 of savings, take-home is about £2,036 a month on full pay and about £0 on half pay alone. NHS sick pay ends around week 17 (month 4), SSP is used up by week 28, and the savings run out in month 6. A shorter scale brings the gap forward by months, which is why length of service matters more than salary when you are working out how exposed you are.

How much difference does other household income make?

A lot. Adding £1,100 a month of take-home income from a partner to the first example changes the result: the savings last the whole 24 months instead of running out in month 14, and the biggest monthly shortfall falls from £1,900 to £800. Use the "Other monthly income while off" field to see your own household version. Include only money you can rely on, and remember that some benefits are affected by a partner's income.

What happens when NHS sick pay runs out?

When the scale for your service is used up, contractual sick pay stops. If you still have SSP weeks left you may receive SSP, but it ends after 28 weeks. What can change the picture:

  • Reinstated half pay (paragraph 14.10). After 12 months of continuous absence, half pay should be reinstated where a final review meeting for long-term absence has not happened because of employer delay. The rules differ for staff with more or fewer than five years' service.
  • Employer discretion (paragraph 14.13). Employers can extend sick pay beyond the scale where a return to work is expected in the short term and an extension would help, or in any other circumstance they consider reasonable.
  • Injury Allowance (Section 22). If your absence is attributable to your NHS work, you may be eligible for a top-up that this calculator does not model.
  • Ill-health retirement. For a permanent condition that stops you doing your job, the NHS Pension Scheme has early-retirement routes. See NHS ill-health retirement explained.
  • Benefits. Universal Credit or New Style ESA may be available depending on your circumstances. Check eligibility on gov.uk before relying on them.
  • Your job. Sick pay entitlement stops from your last day of employment (paragraph 14.3). Long-term absence is managed under your trust's sickness policy, so see long-term sickness and Long Covid support and speak to occupational health and your union early.

Does the NHS offer income protection insurance?

No. NHS contractual sick pay is an employment benefit, not insurance, and it ends when the scale is used up. Commercial income protection insurance is a separate private policy that pays a regular income if illness or injury stops you working, after a waiting period you choose when you buy it. Cost, the waiting period, how long payments continue and how "unable to work" is defined all vary by insurer and by person. Our NHS income protection insurance explained guide covers how these policies work and what to check, and the NHS insurance hub covers life cover, death in service and critical illness.

Do NHS staff need income protection insurance?

There is no single right answer, and this page does not tell you to buy or avoid anything. NHS staff start with a much better sick pay scale than most private-sector employees, so the question is usually about the period after it ends. Questions worth asking of your own results:

  • • When does my NHS sick pay end, and how big is the monthly gap after that, once other income is counted?
  • • How many months would my savings cover, and would I be comfortable with that margin?
  • • Do I have commitments, such as a mortgage or dependants, that would be hard to meet on much less income?
  • • Could a partner's income, ill-health retirement or benefits realistically change the picture?
  • • Am I early in my NHS service, with a short scale, or recently off sick, with less entitlement left than the full scale?

How the calculator works and what it assumes

  • Sick pay phases come from Handbook version 63 (amendment 63, England edition) Section 14: the paragraph 14.2 scale, the 14.6 and 14.8 rule that SSP plus sick pay cannot exceed full pay, and the 14.7 rolling 12-month deduction.
  • SSP is £123 a week or 80% of normal weekly earnings if lower, for up to 28 weeks, assumed to start on day one of the absence (gov.uk, checked 7 October 2026). Earlier linked absences are not modelled.
  • Full pay is your salary as entered. If your pay includes unsocial hours enhancements, note that the Handbook defines full pay for sick pay more narrowly for most staff (paragraphs 14.4 and 14.5), so your real drop may be larger than shown.
  • Take-home pay at each phase is estimated with the site's shared pay engine, treating each pay rate on its own annualised basis. SSP alone is treated as paid in full with no deductions because it falls below the tax and National Insurance thresholds. Actual PAYE during a long absence will differ a little.
  • The chart shows 24 months. After NHS and statutory pay stop, income is only whatever you enter as other monthly income.
  • It is a planning aid and does not replace advice from HR, occupational health, your union or a financial adviser.

Frequently asked questions

Does the NHS offer income protection? +
Not as an insurance product. What NHS staff on Agenda for Change terms have is contractual sick pay under Section 14 of the NHS Terms and Conditions of Service Handbook: between one month's full pay plus two months' half pay in the first year of service, and six months' full pay plus six months' half pay after five years. That is an employment benefit, not income protection insurance, and it ends when the scale is used up. Separately, Injury Allowance (Section 22) can top up pay when an absence is caused by an injury or disease attributable to your NHS work. Commercial income protection insurance is a private product you would buy yourself.
How long does NHS sick pay last? +
It depends on your continuous NHS service when the absence starts. The scale is 1 month full and 2 months half in the first year, 2 and 2 in the second year, 4 and 4 in the third year, 5 and 5 in the fourth and fifth years, and 6 and 6 once you have completed five years. Any paid sick pay you took in the 12 months before the absence is deducted from that entitlement (paragraph 14.7), so a repeat absence can have less than the full scale. The calculator has a field for paid sick weeks in the last 12 months for exactly this reason.
Do I get Statutory Sick Pay on top of NHS half pay? +
Yes, for part of the time. The Handbook says Statutory Sick Pay added to half pay must not exceed full pay (paragraph 14.6), so while you are on half pay and still have SSP weeks left you receive half pay plus SSP. SSP is paid for up to 28 weeks, and the clock starts when your absence starts, so for someone with six months of full pay only about two SSP weeks are left once half pay begins. After that half pay is paid on its own. The rate is £123 a week or 80% of normal weekly earnings if lower (gov.uk, checked 7 October 2026).
What happens when NHS sick pay runs out? +
Contractual sick pay stops when the scale for your service is used up. If SSP weeks remain you may still receive SSP, but SSP ends after 28 weeks, so for most staff with a long scale there is no sick pay at all after the half-pay months. Two Handbook provisions can help: paragraph 14.10 says half pay should be reinstated after 12 months of continuous absence in specific circumstances where a final review meeting has not happened, and paragraph 14.13 lets an employer extend sick pay at its discretion. Benefits such as Universal Credit or New Style ESA may be available depending on your circumstances, so check gov.uk. Employment itself can also end, and entitlement to sick pay stops on your last day of employment (paragraph 14.3).
How much would my income drop if I was off sick long term? +
Use the calculator, because it depends on your pay and service. As an illustration from the same engine, someone with six years' service on a £38,000 salary has take-home pay of about £2,325 a month on full pay, about £1,351 a month on half pay alone, and nothing from the NHS once the scale and SSP are used up. Real tax during a long absence can differ a little from this estimate, so treat it as a planning figure.
Is NHS sick pay based on my full pay including unsocial hours? +
Often not. For staff whose basic pay is above £18,160, and for new starters, the Handbook defines full pay for sick pay as the pay-point salary plus high cost area supplements and any locally agreed pay protection (paragraph 14.5). Regular enhancements for unsocial hours are generally not included. Staff in post on 30 June 2018 with basic pay of £18,160 or less keep sick pay that reflects what they would have received had they been at work (paragraph 14.4). If your take-home usually includes a lot of enhancements, enter a salary that reflects your basic pay and expect the real drop to feel larger than your payslip suggests.
What does the calculator not include? +
It does not model NHS Injury Allowance, reinstatement of half pay after 12 months, employer discretion to extend sick pay, ill-health retirement, or benefits such as Universal Credit and ESA, although you can enter benefits you expect as other monthly income. It assumes the 28-week SSP clock starts on day one with no earlier linked absence and that each pay rate can be taxed on its own annualised basis. Those simplifications are listed on the page so you can judge how far to trust the output for your own situation.
How do I use the results if I am thinking about income protection insurance? +
Look at three things: when your NHS sick pay ends (policies have a waiting period before they pay, and some people choose one that lines up with that date), how large the monthly shortfall is after other income, and how long savings would cover it. Then compare quotes through a whole-of-market broker or an independent financial adviser, because cost, waiting period, payment length and the definition of being unable to work all vary by policy and by person. FrontlinePay does not recommend or sell any insurer or policy and is not a licensed financial adviser.
Does this apply in Scotland, Wales and Northern Ireland? +
The Section 14 scale is the same in the England, Wales and Scotland and Northern Ireland editions of the Handbook, so the pay phases are the same. The calculator has a tax region setting because Scottish income tax bands differ, which changes take-home pay at each phase. Local policies on managing sickness absence differ between employers, so confirm your own position with HR.
Is my information stored or sent anywhere? +
No. The calculation runs in your browser and nothing you enter is sent to FrontlinePay or saved. If you use the copy-link button, your figures are encoded in the link you copy, so only share it with someone you are happy to see them. Printing or saving as PDF uses your browser's own print function.
