How the calculator works
- Your forecast: your weekly State Pension at State Pension age, from your forecast on GOV.UK.
- Deferring: the equivalent of 1% more for every 9 weeks you put it off, for up to 5 years.
- Totals: what you’d get from each starting age to the age you plan for, in today’s money, and the age at which deferring has paid back the payments you missed.
Example
With the full £241.30 a week from 67:
| Start at | A week | Total by 85 |
|---|---|---|
| 67 | £241.30 | £225,857 |
| 68 | £255.24 | £225,632 |
| 69 | £269.18 | £223,958 |
| 72 | £311.01 | £210,243 |
Deferring a year gives up £12,548 but adds £13.94 a week, so it pays off after about 85 and 4 months. Living to 85, claiming at 67 pays slightly more.
