State Pension Calculator

Estimate your weekly and yearly State Pension based on your qualifying years, pension age and any gap years still to fill.

Your Details

Overview

This State Pension Calculator helps you estimate your weekly and annual State Pension using the full pension rate, your current qualifying years, and any years you may still add before reaching State Pension age. It is designed for quick planning rather than an official forecast.

How it works

The calculator estimates your pension as a proportion of the full weekly State Pension. It divides the number of qualifying years counted by the number of years needed for a full pension, then multiplies that fraction by the full weekly amount. It also caps the result at the full pension level so the estimate does not exceed the full rate.

How to use this calculator

  1. 1Enter the full weekly State Pension amount you want to use.
  2. 2Add your current number of qualifying years.
  3. 3Enter how many years remain until you reach State Pension age.
  4. 4Include any extra qualifying years you expect to build or buy.
  5. 5Review your estimated weekly and annual pension amounts.

Frequently asked questions

What does this State Pension Calculator estimate?

It estimates your weekly and annual State Pension using the full pension amount, your qualifying years and any additional years you may still gain.

How many qualifying years do I need for a full State Pension?

Many people use 35 qualifying years for a full new State Pension, but your own situation can differ, so check your official record.

Does this calculator include contracted-out deductions or protected payments?

No. It uses a simple proportional estimate and does not include individual adjustments such as contracted-out history or protected payments.
