Why is my Pension Input zero?

There are two reasons that your Pension Input is zero, page 10 of your Benefit Statement Shows the calculation.

The calculation of your Pension Input makes an allowance for the increase in the Consumer Price Index (CPI), as the CPI allowance for the 2025/26 tax year was 1.7%. So if you did not receive a pay award this will result in a Pension Input of zero.

If you ceased to contribute to the Fund before the start of the 2025/26 tax year then unless you pay Additional Voluntary Contributions, your Pension Input will be zero as the increases that apply to your pension do not count towards Pension Input.
