Teachers' Pension vs Private Pension

The fundamental difference: who carries the risk

Every pension, of any kind, is ultimately a promise to turn money paid in today into an income you can't outlive later. The question that separates a defined benefit scheme from a defined contribution one is simple to state and enormous in its consequences: who is on the hook if it doesn't work out as hoped?

Neither model makes the underlying risk disappear — poor investment returns and long lifespans are real possibilities either way. What differs is who absorbs the consequences: pooled across the whole membership and, because the TPS is unfunded, ultimately underwritten by general taxation, or carried by the individual saver, one pot at a time. This single fact explains almost every other difference covered on this page.

What the Teachers' Pension Scheme actually promises

Since 1 April 2015, every active TPS member has built up new benefits under a career average revalued earnings (CARE) scheme. Each year you're an active member, 1/57th of that year's actual pensionable pay is added to your accrued pension as a guaranteed amount of annual income — not a sum of money invested anywhere. At the end of September following each scheme year, your entire accrued pot is revalued upward by CPI plus 1.6 percentage points, protecting its real value against inflation before you retire. Our full explainer on the 2015 CARE scheme covers the mechanics, the six contribution tiers and worked examples in detail; this page assumes that structure as the baseline and focuses on how it compares with private-sector provision.

What you personally pay in is set by six salary-based contribution tiers, from 7.4% up to 12% of full pensionable pay, banded rather than marginal. On top of that, your school currently pays an employer contribution of 28.68% of your salary — set at the 2020 valuation and effective from 1 April 2024, up from 23.68% before it. Teachers' Pensions has confirmed that following the 2024 valuation, the employer rate is due to fall to 17.68% from 1 April 2027. Whatever the prevailing rate, it never appears on your payslip, which makes it easy to overlook. Nothing about any of this depends on investment performance, because there's no fund behind an individual CARE pot — your income is simply whatever your accrued, revalued pension adds up to.

What a typical private-sector pension actually promises

Since 2012, automatic enrolment under the Pensions Act 2008 has required most UK employers to enrol eligible staff into a workplace pension and to contribute towards it. The default arrangement for the vast majority of private-sector employees is a defined contribution scheme — run by a provider such as NEST, Now: Pensions, Aviva, Legal & General or a similar master trust or insurer — where contributions from both employee and employer are paid into a personal pot and invested, typically in a "default fund" that automatically shifts from higher-risk growth assets towards lower-risk ones as retirement approaches.

Unlike the TPS, there's no formula promising a specific income. The pot is simply worth the sum of contributions paid in, plus or minus investment returns and charges. What income it eventually provides depends on choices made at retirement: buying an annuity (converting the pot into a guaranteed income, transferring longevity risk to an insurer), drawing it down flexibly while it stays invested, or a mix of both. Since the 2015 pension freedoms, DC savers have had wide flexibility over how and when to access this money, generally from age 55, rising to 57 from 6 April 2028 — the same date the TPS's own minimum pension age is separately rising to.

Contribution rates compared: 28.68% against 8%

Set side by side, the contribution rates are one of the starkest differences between the two systems.

Two details widen the gap further. First, the TPS employer rate applies to your entire pensionable salary, while the private-sector 3% minimum applies only to the qualifying earnings band — currently £6,240 to £50,270 for 2026/27 — so a private-sector counterpart earning £45,000 has their employer's minimum calculated on roughly £38,760, not the full amount. Second, even an employer matching pound-for-pound up to 10% of qualifying earnings, genuinely generous by private-sector standards, would typically still contribute a smaller share of total pay than the TPS employer rate provides.

None of this means a TPS member is automatically "better off" in retirement — a formula-based promise and an invested pot aren't directly comparable amounts, which is exactly the point covered next.

Why comparing pot size is misleading

A natural instinct is to ask: what would my TPS pension be worth as a lump sum, so I can compare it to a DC pot of a given size? The honest answer is that this comparison is harder, and the true figure larger, than it first appears — and it's worth explaining why rather than quoting a single number.

A defined benefit promise can be expressed as a hypothetical capital sum in two different ways, and they aren't the same thing. The first is a cash equivalent transfer value (CETV) — what a scheme's own actuary calculates it would need to hand over today to discharge its promise, using the scheme's own assumptions about investment returns, inflation and life expectancy. The second is the cost of buying the equivalent income outright on the open annuity market at retirement — usually a larger figure, because commercial insurers price annuities conservatively and must hold capital against the guarantee they're selling.

A real, published example illustrates the first. XPS Group's Transfer Value Index tracks the cash transfer value available to a defined benefit scheme member aged 64 with a modest £10,000-a-year pension that rises with inflation — a figure that stood at roughly £141,000 at the end of 2025, around 14 times the annual income. Buying a genuinely equivalent, index-linked guaranteed income on the open annuity market can require a noticeably larger multiple again, often cited in the region of 20 to 30 times the annual income, because that figure has to fund the guarantee from an insurer's own conservative pricing rather than a scheme's internal assumptions.

What generalises safely is the direction of the effect: a guaranteed, inflation-linked income for life is genuinely expensive to buy in the open market, and comparing a DC pot's headline balance against a TPS member's "smaller-looking" annual pension figure, without converting one into the other's terms, compares two different units — not two different amounts of value.

Portability: moving your pension between jobs

A defined contribution pot is designed to travel with you. If you change employer, it generally stays exactly as it is — invested, growing or shrinking with the market — and you can usually leave it where it is, transfer it into your new employer's scheme, or consolidate it into a personal pension, largely at your own discretion (subject to normal transfer checks and, for a small number of older policies, exit charges worth checking first). Moving between sectors doesn't fundamentally change what a DC pot is: a personal pot of money that belongs to you.

The TPS works differently. It isn't a personal pot you carry with you — it's an entitlement to future income from a specific, government-backed scheme. If you leave teaching, your accrued benefits don't move anywhere; they become deferred benefits, preserved and revalued within the TPS itself until you claim them from your Normal Pension Age (or earlier, reduced, from 55, rising to 57 from 2028). Transferring that value into a private pension is, for most active and deferred members, not something current rules for unfunded public service schemes even permit, and where theoretically possible it's rare in practice. Our dedicated guide to transferring a Teachers' Pension covers exactly what is and isn't possible for someone who moves between the TPS and a private pension over a career.

Risk in retirement: a promise that can't run out vs a pot that can

The risk difference covered above doesn't stop once you retire — if anything, it becomes the single most practically important distinction of all. A TPS pension, once you're drawing it, simply cannot run out. However long you live — twenty years into retirement or forty — the scheme continues paying the same guaranteed, inflation-protected income, because that was the nature of the promise from the start. A TPS pensioner never has to model how long their money needs to last, because the question doesn't arise.

A DC pot that hasn't been converted into a guaranteed income is a finite sum, and it can be exhausted. Drawing it down too quickly, poor investment returns early in retirement, or simply living longer than planned for can leave a saver without enough left in later life. This is why the choice of how to take a DC pot matters so much: buying a lifetime annuity converts it into a guaranteed income and passes the longevity risk to an insurer, in effect recreating a TPS-like guarantee for that money; staying invested and drawing down flexibly keeps more control and potential upside, but keeps the risk of running out with the saver — which is why careful, often professionally guided withdrawal planning is something DC savers need to think about in a way a TPS member never does.

The real trade-off for teachers considering a career change

Everything above adds up to a genuine, specific consideration for a teacher weighing up a move into a private-sector role with typical DC provision, worth stating plainly without telling anyone what to do about it. Leaving the TPS for a DC-only employer means moving future pension saving from a guaranteed, inflation-linked income for life into a personally owned pot whose eventual value depends on investment markets, contribution levels and drawdown decisions still to be made. It doesn't mean losing what's already built up — your accrued TPS service becomes a preserved, revaluing deferred pension sitting alongside whatever DC pot you go on to build — but it does mean all further pension saving carries a materially different risk profile than it did as a serving teacher.

This is a real, structural fact about the decision, not a reason on its own to stay in or leave the profession. Some people place real value on the certainty of a defined benefit promise; others on the ownership, flexibility and potential upside of a personal pot, or on a private-sector role's wider package or prospects. Both are legitimate ways to weigh the decision, and the right answer depends on someone's whole financial picture — not on pension structure alone.

• Get a statement of your accrued TPS benefits first — see our guide to reading your benefit statement.
• Check what your new employer actually contributes — the statutory 3% minimum, or more.
• Your accrued TPS pension keeps being revalued by CPI+1.6% even after you stop contributing, so leaving doesn't freeze its real value.
• Pre-2015 service sits under different final-salary rules — see our 2015 CARE scheme guide.
