Why two people the same age get different State Pensions

Two people can retire in the same month, in the same street, with the same number of years at work — and receive State Pensions that differ by £40 a week or more. The reason is almost never a mistake. It is the National Insurance record behind each entitlement, and a set of rules that changed in 2016.

The full new State Pension is £241.30 a week in 2026/27. That figure gets quoted so often that it is easy to read it as the amount pensioners receive. It is not. It is the maximum under one of the two systems the UK runs in parallel, and reaching it depends on a record that was built up over decades of working life.

Once you understand what sits behind the number, the differences between neighbours stop looking arbitrary.

Qualifying years are the unit of account

The State Pension is built from qualifying years. A qualifying year is a tax year in which you either paid enough National Insurance through employment or self-employment, or were credited with it — while claiming Child Benefit for a child under 12, for example, or while receiving certain benefits such as Jobseeker's Allowance or Carer's Allowance.

Under the new State Pension, the thresholds are:

• 35 qualifying years for the full rate.
• At least 10 qualifying years to receive anything at all.
• Between 10 and 35, the amount is broadly proportionate.

Under the older basic State Pension, which applies to men born before 6 April 1951 and women born before 6 April 1953, the full rate needed 30 qualifying years and the full 2026/27 basic rate is £184.90 a week.

That difference alone — 30 years versus 35 — accounts for some of the variation between people who retired a few years apart. But it is rarely the biggest factor.

Contracting out is the usual explanation

Between 1978 and April 2016, it was possible to be contracted out of the Additional State Pension — the earnings-related top-up known at different times as SERPS and then S2P. Millions of people were, often without giving it much thought, because their employer's pension scheme was contracted out as a matter of course. Most public sector schemes were, and so were a great many private final-salary schemes.

In exchange, the employee and the employer both paid a lower rate of National Insurance, and the workplace scheme took on the job of providing at least as much as the Additional State Pension would have done.

So a contracted-out worker paid less in and built less State Pension — but built more workplace pension instead. Looking only at the State Pension figure makes that person appear worse off. Looking at total retirement income usually tells a different story.

a common misreading

A State Pension below the full rate because of contracting out is not an error and not money lost. The corresponding amount was built up in a workplace scheme instead. Comparing one component in isolation gives a misleading picture of either person's position.

The 2016 starting amount

When the new State Pension began on 6 April 2016, everyone with a National Insurance record had a starting amount calculated. It is the higher of two figures:

• what the person would have received under the old rules — basic State Pension plus any Additional State Pension; or
• what they would have received under the new rules, less a deduction for any period of contracting out.

That deduction is the Contracted Out Pension Equivalent, usually shortened to COPE. It is an estimate of the Additional State Pension forgone by being contracted out, and it is the single most common reason a forecast comes in below the headline rate.

Taking the higher of the two calculations means nobody lost out at the point of transition. But it does mean two people with identical working lives on paper can start from different places, purely because of which pension schemes their employers happened to run.

What that looks like in practice

The clearest way to see it is with two illustrative cases. Both were born in the same month, both reached State Pension age in 2026, and both have 35 qualifying years.

Margaret reaches the full new State Pension. David does not — but he has a local authority pension that Margaret does not have. Neither has been treated unfairly. They simply built their retirement income in different proportions, and the State Pension line shows only one of those proportions.

Protected payments work the other way

The arithmetic can also run in the opposite direction. If someone's 2016 starting amount came out higher than the full new State Pension — typically because they had built up a substantial Additional State Pension and were never contracted out — the excess is kept as a protected payment.

That is why some pensioners receive more than £241.30 a week. It is worth noting that a protected payment is normally uprated in line with inflation rather than under the Triple Lock, so it tends to grow more slowly than the main rate. The same applies to Additional State Pension generally, which is why a single percentage cannot be applied across the whole of a mixed entitlement. We looked at that in this annual State Pension increase affects millions in Britain.

The other things that move the number

Beyond contracting out, several circumstances commonly shift an individual entitlement:

• Years spent abroad. Working outside the UK generally does not build UK qualifying years, though some social security agreements allow foreign contributions to count towards eligibility.
• Low earnings. Earning below the lower earnings limit in a tax year, or spreading earnings across several small jobs, can mean the year does not qualify.
• Self-employment. Class 2 contributions build qualifying years; profits below the relevant threshold have different treatment depending on the year in question.
• Caring and parenting. National Insurance credits for Child Benefit and for carers fill years that would otherwise be blank — but only where the claim was actually made.
• Inherited entitlement. A widow, widower or surviving civil partner may be able to inherit part of a late spouse's Additional State Pension or protected payment.

How to see your own record

The National Insurance record is not a mystery document. GOV.UK publishes it, free, through the Check your State Pension forecast service, which shows the years that counted, the years that did not, and the forecast that follows. It also shows the COPE figure where one applies.

That is the number that matters for any individual — not the headline rate. If a year looks wrong, it is worth querying: records occasionally miss credits that should have been applied, particularly around periods of caring or Child Benefit claims made in a partner's name. Our piece on what a gap in your National Insurance record actually costs goes through the options where years really are missing, and what a pension forecast can and cannot tell you covers the limits of the service itself.

The point worth taking away

The full rate is a ceiling, not a default. Most of the gap between two pensioners the same age comes down to contracting out, and that gap usually has a matching workplace pension sitting behind it. The only figure that describes a particular person is the one on their own forecast or award letter.
