Deferring your State Pension increases what you eventually receive — but the exact rate depends on which State Pension system you're on, and it isn't quite as simple as "wait a year, get a year's worth more". Here's exactly how the increase is calculated.
The new State Pension deferral rate
If you're on the new State Pension, your weekly amount increases by just under 1% for every 9 weeks you defer — which works out to just under 5.8% for every full year deferred. There's no cap on how long you can defer, so the longer you wait, the larger the eventual increase, compounding roughly in line with that rate.
Worked examples on the full 2026/27 rate
Say Wendy reaches state pension age with a full new State Pension entitlement of £230.25 a week, but decides to keep working and defers her claim for exactly two years. Her eventual weekly amount would rise by roughly 11.6%, taking it to around £257.00 a week for the rest of her life — a permanent increase, not a one-off bonus.
The basic State Pension deferral rate is different
If you're on the basic State Pension (state pension age reached before 6 April 2016), the deferral rate is more generous per year — historically around 10.4% for every full year deferred. Under the basic system, if you deferred for at least 12 months, you also had the option to take a one-off lump sum instead of an increased weekly rate, an option that isn't available under the new State Pension. Since the two systems have different rates and rules, it's worth confirming which one applies to you — see our guide on new vs basic State Pension if you're not sure.
Things worth knowing about the increase
-
1
The increase is permanent once you claim — it isn't a temporary bonus that tapers off.
-
2
You don't need to apply to defer — it happens automatically simply by not claiming when you first become eligible.
-
3
You can change your mind and claim at any point — there's no minimum deferral period required.
-
4
The increased rate still rises each year afterwards under the normal annual uprating rules, on top of the deferral boost.
-
5
Deferring doesn't affect any other pensions or benefits you're already receiving, but check how it interacts with means-tested benefits if you claim any.
How this fits your wider plan
A permanently higher weekly State Pension can be a useful way to increase guaranteed, inflation-linked income later in retirement, particularly if you're comfortable funding the deferral period from other sources. See our guide on how much you need to save for retirement for how a deferred State Pension might fit alongside your other income in later life.

A word of caution
These figures are illustrative examples based on 2026/27 rates and standard deferral rules — they aren't personalised financial advice, and your own numbers will depend on your exact State Pension amount and circumstances. If you're weighing up deferring, it's worth getting your specific figures confirmed by the Pension Service, and considering guidance from MoneyHelper (moneyhelper.org.uk) or a regulated adviser before deciding.
How the rate has changed over time
The current new State Pension deferral rate of just under 5.8% a year hasn't always applied — it was set when the new State Pension launched in 2016 and reflects a more conservative rate than the roughly 10.4% a year that applied under the old basic State Pension system. This change was deliberate, reflecting the government's view of what a fair, actuarially balanced rate looks like, but it does mean older guidance or examples referencing the higher historical rate can be misleading if applied to the new system.
Because the rate is set by government policy rather than a fixed formula linked automatically to interest rates or life expectancy, it's technically possible for the rate to change again in the future, though there's no current indication of an imminent change. It's worth double-checking the current rate at the time you're actually considering deferring, rather than relying purely on historical figures, including the ones in this guide.
Comparing deferring to other ways of increasing retirement income
Deferring isn't the only way to increase your eventual retirement income, and it's worth comparing it against alternatives such as continuing to build up a workplace pension, making additional voluntary contributions to a private pension, or paying voluntary NI contributions to fill gaps in your qualifying years if you haven't yet reached 35. Each of these options has different risk profiles, tax treatments, and flexibility, so the right choice — or combination of choices — depends on your full financial picture, not just the deferral rate in isolation.
One advantage deferring has over most alternatives is that it requires no investment risk and no upfront lump sum — you simply don't claim the income you'd otherwise receive. This makes it a genuinely low-complexity option for anyone who doesn't need the income immediately, though it does mean that money isn't available to you at all during the deferral period, unlike some other retirement savings vehicles that allow partial access.
What happens if you die during a period of deferral
If you die while your State Pension is deferred and you haven't yet claimed the increased amount, what happens to that unclaimed increase depends on your specific circumstances, including whether you have a surviving spouse or civil partner and the rules in place at the time. In some circumstances, a surviving spouse may be able to inherit some benefit from a deferred period, though this is a genuinely complex area that depends heavily on individual rules and dates.
If this is a concern — for example, if you're considering a long deferral period and want to understand what would happen to your family in the event of your death during that time — it's worth getting a clear, personalised answer from the Pension Service or a regulated adviser before committing to defer for an extended period, rather than assuming a particular outcome without checking.
How to keep track of your deferral period accurately
Because the exact increase depends precisely on how long you defer, it's worth keeping a clear personal record of the date you became eligible to claim and the date you eventually do claim, rather than relying on memory or an approximate estimate. This is particularly important if your deferral period spans several years, since even small discrepancies in the dates used can affect the exact percentage increase applied to your eventual weekly amount.
When you do eventually claim, the Pension Service will calculate your exact deferral increase based on their own records, but having your own note of the relevant dates can help you spot and query any discrepancy quickly, rather than assuming their calculation is automatically correct without an easy way to check it yourself.
How the increase interacts with future annual uprating
A subtlety worth understanding is that your deferral increase is applied as a percentage on top of your standard entitlement, and from that point on, the increased amount rises each year under the normal triple lock uprating alongside everyone else's State Pension. This means the value of your deferral increase compounds over time in real terms, not just as a one-off boost — a permanently higher base amount that itself grows with inflation and earnings each subsequent year, rather than a fixed cash increase that gradually loses value to inflation.
This compounding effect is one of the reasons deferring can be particularly valuable for people expecting a long retirement, since the advantage of a higher base amount, itself growing under the triple lock, tends to widen further the longer you receive it compared to someone who claimed at the standard rate.
Putting a specific number on your own decision
To translate this guide's general figures into your own specific decision, start with your own State Pension forecast amount rather than the standard full rate used in the examples here, and apply the same percentage increases to calculate what deferring for one, two, or five years would actually mean for you personally. This personalised calculation, rather than relying on the illustrative full-rate figures in this guide, gives you the accurate numbers needed to weigh up your own decision properly.
Once you have your own specific figures, it's worth revisiting our companion guide on whether deferring is worth it to work through the break-even analysis using your actual numbers rather than the general examples, giving you a much more precise picture of whether deferring makes sense for your particular circumstances.
The essential numbers to remember
If you remember nothing else from this guide, remember that the new State Pension increases by just under 5.8% for every full year you defer, with no cap on how long you can wait, while the older basic State Pension increased at a more generous roughly 10.4% per year and also offered a lump sum option. These rates apply on top of your own personal State Pension amount, not the standard full rate used in the examples throughout this guide, so always translate the percentages into your own specific figures before making a decision.
Whatever your own numbers turn out to be, the increase is permanent, automatic (no application needed to start deferring), and continues to rise each year under the normal annual uprating alongside everyone else's State Pension — making it one of the more straightforward, low-risk ways to increase your guaranteed retirement income, provided deferring otherwise fits your personal circumstances and health outlook.
Confirming your own specific figures
Before making any decision based on the percentages and examples in this guide, confirm your own specific State Pension amount and check the current deferral rate directly with the Pension Service, since these figures form the basis of any accurate personal calculation. MoneyHelper's free guidance service can help you translate the general rules into your own numbers, while a regulated financial adviser can build a more detailed model if your circumstances involve multiple income sources or a complex tax position.
Getting these specific figures confirmed, rather than relying purely on the illustrative examples in this guide, ensures any decision about deferring is grounded in your actual entitlement rather than a general approximation that may not precisely match your own circumstances.
A final summary
To recap: the new State Pension increases by just under 5.8% for every full year deferred, with no cap on how long you can wait, while the basic State Pension historically increased at roughly 10.4% per year with a lump sum option. These increases are permanent and continue to rise under the normal annual uprating rules alongside your standard entitlement.
Translate these percentages into your own specific State Pension amount before making any decision, and weigh the result against your health, tax position, and income needs, ideally alongside our companion guide on whether deferring is worth it for the full break-even picture tailored to your own circumstances.
