Police Pension Calculator

A multi-year worked example

To see how the slices accumulate, imagine an officer with the simplified five-year pensionable pay history shown below, including a promotion to Sergeant in Year 4.

If none of these slices were revalued at all, the simple sum across the five years would be about £3,446 built up from those five years of service alone. In reality, each year's slice is also revalued by CPI plus 1.25% for every year between when it was earned and when the pension is actually drawn, so the true figure by retirement would be higher than this simple sum — often considerably higher for slices earned early in a long career, since they benefit from the most years of revaluation. This calculator's projection includes that revaluation effect; the simple sum above is shown only to illustrate how the individual year-by-year slices stack up before revaluation is applied.

Why CPI+1.25% revaluation matters so much over a career

The revaluation rate — CPI plus 1.25 percentage points, applied every year — is one of the most valuable and least understood features of the scheme, particularly for pension built up early in your service. Because each year's slice keeps being revalued for every subsequent year of your career, a slice earned in your first year of service, if you go on to serve for 25 or 30 years, gets a very large number of years of compounding revaluation applied to it before you draw your pension.

It is not possible to know in advance exactly what CPI will average over the remainder of a career decades in length, and this calculator does not attempt to guess a specific long-run inflation figure — doing so would give a false sense of precision about numbers that are inherently uncertain that far into the future. What is worth understanding conceptually, though, is the compounding nature of the mechanism: revaluation applies to the growing pot of already-accrued pension each year, not just to that year's new slice, so the effect builds on itself over time in a way that a flat, non-compounding increase would not. This is a considerably more generous design than simply leaving early-career pension slices unchanged in cash terms until retirement, and it's one of the reasons the 2015 scheme, despite being less generous in some respects than the older final-salary schemes it replaced, still represents a substantial and valuable retirement benefit.

Accrued pension versus projected pension: what the breakdown shows you

This calculator distinguishes between two figures, and it's worth being clear about the difference. Accrued pension is the pension you have already, definitively, earned based on your actual service and pensionable pay to date — this is the figure that, broadly, would appear on your Annual Benefit Statement, subject to revaluation being applied to it going forward each year until you draw it.

Projected pension takes your accrued position and extends it forward, using assumptions you provide (such as your expected future pensionable pay and years remaining until retirement) to estimate what your total pension might be by the time you actually retire. This projected figure is necessarily less certain than the accrued figure, because it depends on assumptions about the future — your pay progression, whether you're promoted, whether your working pattern changes, and so on — none of which can be known with certainty in advance.

Both figures are useful for different purposes. The accrued figure is useful for understanding where you stand right now, and for sense-checking against your official Annual Benefit Statement. The projected figure is useful for longer-term planning — thinking about when you might realistically be able to afford to retire, and roughly what income you might have when you do — while bearing in mind that it is an estimate, not a guarantee, and will need to be revisited periodically as your actual circumstances become clearer.

Why a real forecast will differ from this simplified tool

This calculator necessarily simplifies a number of things that a full, formal pension forecast would take into account in detail, and it's worth understanding what those simplifications are so you don't treat the output as more precise than it's intended to be.

Pay progression is the biggest source of difference. Real careers rarely involve a smooth, predictable increase in pay each year — there are promotions that happen at a particular point rather than gradually, pay scale increments that may or may not be awarded depending on performance, and periods where pay might not rise at all, for example during a pay freeze or if annual PRRB-recommended increases are modest in a particular year. This calculator asks you to provide reasonable assumptions about future pay, but the further into the future you're projecting, the less reliable any single assumption becomes.

Part-time periods are another significant factor. If you work part-time for any part of your career — whether for a few months or several years — your pensionable pay, and therefore the pension slice added for those years, will be correspondingly lower, and a projection that assumes continuous full-time service throughout will overstate your eventual pension if that assumption doesn't hold.

The actual path of CPI inflation over the coming years and decades is unknowable in advance, and this calculator uses a simplified assumption for illustrative purposes rather than attempting to forecast inflation precisely. Real-world CPI will fluctuate — sometimes higher, sometimes lower, than any single assumed rate — and over a long career these year-to-year differences can meaningfully change the eventual outcome in either direction.

Because of all this, treat the projected figure as a reasonable planning estimate to help you think about the shape of your retirement income, not as a guaranteed number. The further away your expected retirement date, the wider the realistic range of outcomes becomes.

Getting an official Annual Benefit Statement

For a precise, authoritative record of your actual accrued pension, your Annual Benefit Statement (ABS) is the document to rely on rather than any calculator, including this one. Your ABS is produced annually by your pension scheme administrator (this varies by force, but is often accessed through a dedicated online pension portal) and sets out your actual accrued benefits based on your real service and pay history recorded on the scheme's systems, along with a modelled projection to retirement using the scheme's own standard assumptions.

If you haven't checked your ABS recently, it's worth logging into your scheme's member portal to view it, and worth checking it against your own understanding of your service history and pay — errors do occasionally occur, for example if a period of part-time working, a transfer of previous service, or a pay change wasn't correctly recorded, and these are far easier to correct closer to the time they occurred than years later when records and memories have faded. If anything on your ABS looks inconsistent with your actual employment history, your force's pensions team or HR department is the right place to query it.

How commutation would adjust the figures shown here

At retirement, members of the Police Pension Scheme 2015 have the option to exchange part of their annual pension for a one-off tax-free lump sum, a process known as commutation. The exchange rate is £12 of lump sum for every £1 of annual pension given up, and the amount you can commute is capped at 25% of the capital value of your pension benefits.

This calculator's headline projected annual pension figure is shown before any commutation, because how much (if any) of your pension you choose to exchange for a lump sum is a personal decision made at the point of retirement, depending on your circumstances at the time — for example whether you have a mortgage to clear, other lump sum needs, or a strong preference for maximising guaranteed annual income instead. If you commute the maximum available, your annual pension income will be correspondingly lower than the figure shown here, in exchange for a substantial tax-free lump sum at the £12:£1 rate.

Retiring early: Normal Pension Age, minimum retirement age and reductions

The Police Pension Scheme 2015 has a Normal Pension Age of 60, and it's this age that the unreduced pension figures produced by this calculator are generally based on. It is possible to retire and start drawing your pension earlier than 60, from as early as age 55, but doing so applies an early retirement reduction to your annual pension, since the pension will, on average, be paid out over a longer period than if you'd waited until Normal Pension Age.

The reduction applied for retiring early is not a flat percentage regardless of how early you go — broadly speaking, the earlier before age 60 you draw your pension, the larger the proportional reduction, since the scheme is adjusting the annual amount to reflect the extra years over which it expects to be paid. This calculator's headline figures assume drawing your pension at Normal Pension Age; if you're specifically planning to retire earlier than 60, treat the projected figure here as the starting point before an early retirement reduction is applied, and, as with commutation, take advice or use your scheme administrator's specific early retirement figures when you're within a few years of actually making that decision, since the precise reduction factors are set by the scheme and can be obtained accurately from your pension administrator rather than estimated generically.

It's also worth distinguishing voluntary early retirement, discussed above, from any separate arrangements that may apply in cases of ill health or other specific circumstances, which are governed by different rules within the scheme and are not modelled by this general-purpose calculator. If your circumstances involve anything other than a standard voluntary retirement, speak to your force's pensions team directly for guidance specific to your situation.

BTP PensionPlus: same rates, different delivery — and a real NI saving

Officers in the British Transport Police are members of exactly the same Police Pension Scheme 2015 as officers in Home Office forces, on exactly the same tiered employee contribution rates and the same 35.3% employer contribution rate described elsewhere on this page. There is no separate BTP contribution structure and no different rate; the rates are identical.

What is different is how BTP collects those contributions. Rather than the standard net pay arrangement used by most forces, where your pension contribution is simply deducted from your pay before tax, BTP uses a salary sacrifice arrangement called PensionPlus. Under salary sacrifice, your contractual salary is technically reduced by the amount of your pension contribution, and your employer pays that amount into the scheme on your behalf instead. The contribution itself is still calculated using the same tiered rates as everywhere else — salary sacrifice changes how the contribution is delivered, not how much is contributed.

This is a genuinely valuable difference, though, because of how it interacts with National Insurance. A standard payroll deduction reduces your taxable pay but not your National-Insurance-able pay, so you still pay NI on the portion of your salary that goes into your pension. Salary sacrifice reduces your headline salary itself, which means it reduces your NI-able pay too — so BTP officers under PensionPlus pay slightly less National Insurance than an officer on an identical salary making the equivalent contribution under the standard deduction method. The saving is modest, but it's a real, ongoing benefit that officers in forces using the standard arrangement don't get.

The underlying CARE accrual rate of 1/55.3 and the CPI+1.25% revaluation described above apply to BTP officers in exactly the same way as everyone else, since they're building up benefits in the same scheme. If PensionPlus applies to you, this calculator's projected benefit figures and the tiered contribution rates described throughout this page both apply directly to your situation — the only thing to expect on your payslip is that your gross salary figure will reflect the salary sacrifice reduction, which is normal and is exactly what delivers the National Insurance saving described above, not a sign that a different rate has been applied.
