Is it worth topping up your State Pension?
Buying one missing National Insurance year for 2026/27 costs about £957 and adds roughly £359 to the State Pension every year for life, normally paying back in about 2 years 8 months, under gov.uk's voluntary National Insurance contributions rules. Always check your own forecast first.
How does the State Pension top-up work?
The new State Pension is built from qualifying National Insurance years, under the rules set out on gov.uk's new State Pension page. You need about 35 years for the full amount, and each year is worth one thirty-fifth of it. If you have gaps, for example from time abroad, low earnings or caring years that were not credited, you can often pay to fill them with voluntary Class 3 contributions, as explained on gov.uk's voluntary National Insurance contributions page.
| Cost of one full year (Class 3, 2026/27) | £18.40/week · £957/year |
|---|---|
| Extra pension one year buys | £6.89/week · £359/year |
| Break-even | about 2 years 8 months |
What would a worked example look like?
Suppose you have three gap years you can fill. At about £957 each, that is £2,870 up front. It lifts your State Pension by roughly £1,076 a year, every year, for the rest of your life. After about 2 years 8 months the outlay is recovered, and everything after that is gain. Over a typical 20-year retirement those three years are worth about £21,510 in extra pension, a net gain of £18,640.
What should I check before I pay?
- Check your forecast first. Log in to your gov.uk State Pension forecast to see your gaps and whether filling a year actually raises your amount. Some years, especially recent ones you are still building, will not.
- Note the deadlines. You can usually go back six tax years; older years have special deadlines.
- Call the Future Pension Centre. They confirm which specific years are worth buying for you. This is free.
Common questions
Is it worth topping up my State Pension?
That depends on how long the pension is drawn and on whether the gap year can be filled another way. One voluntary Class 3 year costs about £957 and adds roughly £359 to your State Pension every year for life. That pays for itself in about 2 years 8 months, so a payment is recovered only if the pension is drawn for longer than that. Always check your State Pension forecast first, because some years will not increase your pension.
How much does one year of voluntary National Insurance cost?
A full Class 3 year for 2026/27 costs about £18.40 a week, which is about £957 for the year. Older years can sometimes be cheaper or dearer.
How much does one extra year add to my pension?
The full new State Pension is based on 35 qualifying years, so one year adds one thirty-fifth of it, about £7 a week, or roughly £359 a year.
Why can gov.uk not tell me if a year is worth buying?
The forecast shows your record and the cost, but not whether a specific year raises your own pension, which depends on your full history. That is the gap this tool helps you reason about. Confirm with the Future Pension Centre before you pay.
