Defined Benefit Estimator

Last Updated: 26th July 2025

How to use this calculator

Start by entering your final salary (or your expected salary at retirement), your scheme’s accrual rate (such as 1/60 or 1/80), and the total number of years you expect to have as pensionable service.

Enter your planned retirement age and your current age if you have not yet reached retirement. The revaluation rate field allows you to reflect how your pension benefits might increase each year before you retire, in line with common scheme practice.

As you update any details, the calculator will immediately display your estimated pension based on today’s values, as well as a projection of your pension at retirement after annual revaluation. You can view a breakdown of how your benefits accumulate year by year, and adjust any input to see the effect on your projected income.

The figures will update automatically as you make changes, there’s no need to press a submit button.

How this calculator works

This calculator estimates the annual pension you could receive from a defined benefit (final salary) scheme, based on the details you provide: final salary, accrual rate, years of service, retirement age, current age, and revaluation rate.

The calculation uses the following formula:

Annual pension = Final salary × Accrual rate × Years of service

The estimated pension at retirement is calculated by increasing the base pension each year between your current age and retirement age using the revaluation rate you specify. This reflects the way most schemes increase deferred benefits before they are paid.

The results show both your annual pension based on today’s salary and service, and a projection at your chosen retirement age after revaluation.

The table details how your pension entitlement builds up over time, both with and without revaluation.

Understanding the limitations of this calculator

This calculator does not provide a formal pension statement or guarantee your actual benefits. It cannot account for every scheme rule, such as early or late retirement factors, commutation for tax-free cash, split accrual rates, salary changes, part-time service, or career breaks. I

t does not include scheme-specific protections, minimum or maximum pension limits, or discretionary increases. No allowance is made for survivor or dependent pensions, children’s benefits, or the tax treatment of income.

The projections do not model inflation after retirement, changes to legislation, or the effect of taking benefits in different ways.

The figures are illustrative only and are not a substitute for information from your scheme administrator or regulated financial advice.

or straightforward cases using a single accrual rate and continuous full-time service, this calculator produces estimates that are generally close to what would be expected under most mainstream defined benefit schemes.

The formula and revaluation method are based on standard UK practice, and the figures are suitable for everyday scenario testing and broad planning.

However, most schemes have additional rules, exceptions, and options that can affect the actual pension you will receive. If your service is not continuous, your salary history is complex, or your scheme has unusual features, your benefits may differ from these estimates.

The calculator provides a realistic guide for typical situations, but your final entitlement may be higher or lower than the results shown.
