How the Retirement Date Calculator works
Your retirement date is your birthday in the year you reach the chosen age, plus any extra months. State pension ages differ by country and birth year, so check the official age for you.
If you were born on the 29th to 31st and the target month is shorter, the last day of that month is used.
The formula
Worked example
Using the default values shown in the calculator:
| Date of birth | 1980-05-20 |

| Retirement age (years) | 65 |
| Plus months | 0 |
| Today | 2026-10-17 |
- Born 20 May 1980, retiring at 65: Saturday, 20 May 2045.
- That is 6,790 days or about 18.6 years away.
