How to use this calculator

Choose Pension pot to project savings from personal and employer contributions, or Salary-based pension to estimate a defined-benefit payment from your scheme’s salary, service and accrual inputs. These are different pension types; the calculator does not determine eligibility or an official entitlement.

Project a contribution-based pension pot

Enter your current pot and monthly amounts actually paid in by you and your employer. Contributions stay fixed in nominal currency and enter at month-end. Growth uses an annual effective return after fees, converted to an equivalent monthly rate. Today’s-money results divide the future pot by cumulative assumed inflation.

The withdrawal percentage estimates an initial annual amount from the projected pot. Dividing by twelve gives a monthly illustration. It is not an annuity quote, a safe withdrawal recommendation or a simulation of how long the pot will last. Use the Retirement Calculator for a separate retirement withdrawal scenario.

Estimate a salary-and-service benefit

The simple formula is annual pension = pensionable salary × credited service years × accrual percentage × (1 − reduction percentage). Use your scheme’s definition of pensionable salary and credited service. A scheme that earns 1/60 of pay per year uses an accrual percentage of approximately 1.6666667%.

Some pensions use tiered accrual rates, career-average revaluation, caps, survivor reductions or other adjustments. This calculator does not reproduce those rules or estimate a State Pension or Social Security award. Get an official benefit statement before making decisions; selecting a currency changes display only.

Worked pension examples

At 0% growth, a 10,000 pot plus 200 personal and 100 employer contributions each month becomes 13,600 after one year. A 4% initial withdrawal is 544 annually, or about 45.33 monthly. For a salary-based scheme, 60,000 salary × 30 service years × 1.5% accrual gives 27,000 annually, or 2,250 monthly, before tax and any scheme reductions.
