mccloud judgement calculator

What is the McCloud judgement?

The McCloud judgement arose from age discrimination findings in UK public service pension reforms. In short: younger members were moved into reformed schemes while some older members received transitional protection. Courts found the protection was unlawful age discrimination.

The government response introduced a remedy period (1 April 2015 to 31 March 2022), where affected members can receive benefits based on whichever scheme treatment applies under remedy rules. This is often discussed as the deferred choice underpin for many schemes.

Who this calculator is for

This page is useful for members of public service pension schemes who want a quick estimate before receiving official statements. It can help with rough planning if you are in schemes such as:

• NHS Pension Scheme
• Teachers' Pension Scheme
• Civil Service Pension Scheme
• Police and Firefighters' Pension Schemes
• Other public service arrangements impacted by McCloud remedy

Because each scheme has unique details, this estimator should be treated as directional, not definitive.

How this calculator works

1) It estimates annual pension from remedy-period service

The calculator uses a simple accrual model:

• Legacy annual pension = pay × remedy years ÷ legacy denominator
• Reformed annual pension = pay × remedy years ÷ reformed denominator

2) It compares legacy vs reformed value

You get an estimated yearly gain (or loss) depending on which scheme produces the higher pension for that service slice.

3) It estimates arrears and simple interest

If legacy appears better and you are already retired, you can enter years of underpayment. The tool then provides a rough arrears estimate and simple interest estimate.

4) It shows possible lump-sum difference

Some legacy arrangements include an automatic lump sum (often 3× pension slice). Reformed schemes are frequently pension-only by default. This tool models that gap using your chosen lump-sum multiple.

How to use it effectively

• Use pensionable pay that best matches your scheme rules (career-average pay or final salary context).
• Enter only service inside the remedy window.
• Double-check accrual denominators from your scheme booklet.
• Use 0 for underpaid years if you have not retired yet.
• Run multiple scenarios with different pay assumptions to see sensitivity.

Example scenario

Suppose you enter: pay £50,000, remedy service 7 years, legacy accrual 1/80, reformed accrual 1/57, and legacy lump-sum multiple 3. The calculator might show the reformed scheme provides a higher annual pension (because 1/57 generally accrues faster than 1/80), while legacy might still offer a larger automatic lump sum. That trade-off is exactly why comparison matters.

Important limitations

• Does not model inflation revaluation mechanics in full detail.
• Does not include actuarial adjustments for early/late retirement.
• Does not include tax treatment, annual allowance, or lifetime allowance history.
• Does not reflect all scheme-specific protections and service breaks.
• Not legal, tax, or financial advice.

Next steps after your estimate

If the estimate suggests a material difference, you should:

• Request your formal remedy statement from scheme administrators.
• Review option packs and timelines for making elections.
• Speak to a regulated financial adviser if retirement decisions are near.
• Keep records of service history, pensionable earnings, and correspondence.

A clear estimate now can make official remedy choices less stressful later. Use the calculator as your first pass, then validate against formal scheme data.
