Annuity Calculator — Retirement Income

Annuity rates are calculated by insurers based on your pension pot size, age at purchase, health status, and chosen options. The insurer invests your lump sum and pays you a guaranteed income for life, using actuarial life expectancy tables and current gilt yields to determine the annual payout. A larger pot, older age, or poor health typically produces a higher annual income.

You select between a single-life annuity (pays only you) or a joint-life annuity (continues paying a spouse at a reduced rate, typically 50-66%). Level annuities pay a fixed amount, while escalating annuities start lower but increase each year by a fixed percentage or in line with RPI, protecting against inflation erosion over a 20-30 year retirement.

The calculation divides your pot by an annuity factor derived from mortality tables and the selected options. Guarantee periods (typically 5 or 10 years) ensure payments continue to beneficiaries if you die early, but reduce the headline rate slightly. Enhanced annuities for smokers or those with medical conditions can pay 20-40% more than standard rates.

Why are UK annuity rates so much better in 2026? After 15 years of historically low gilt yields suppressing annuity rates, the Bank of England base rate rises (4.5% as of May 2026) and 15-year gilt yields above 4.5% have transformed pricing. A 65-year-old buying a single-life, level lifetime annuity with £100,000 in May 2026 can secure £7,200-£7,500/year — compared to ~£5,500 in 2020. Adding inflation protection (RPI-linked, 3% escalating) typically reduces the starting income by 35-45% but protects purchasing power over a 20-30 year retirement.

Lifetime vs Fixed-Term vs Enhanced annuities. A lifetime annuity pays for as long as you live. Fixed-term annuities (5, 10, 15, or 20 years) pay a guaranteed income then return a maturity value — useful if you want flexibility but worry about drawdown sequence-of-returns risk. Enhanced annuities pay 10-40% more if you have qualifying medical conditions (smoking, diabetes, heart conditions, cancer history, high BMI, etc.) because the insurer expects to pay out for fewer years. Around 60% of annuity buyers qualify for enhanced rates but many never check — always shop the enhanced market via specialist brokers.

Joint-life annuities for couples. If you have a spouse or civil partner, consider a joint-life annuity (50%, 66%, or 100% spouse pension). A 100% spouse joint annuity for two age-65 partners pays ~15% less than a single-life annuity, but continues at the same rate after first death. With UK life expectancy of 82 for men and 85 for women, joint annuities almost always pay out more in total. They are particularly valuable when one partner has significantly more pension wealth than the other.

When does an annuity beat drawdown? Annuities provide insurance against longevity — running out of money. They are most valuable for those without a defined benefit pension safety net, who do not want to manage investments in old age, or who fear cognitive decline affecting financial decisions. Drawdown wins for those who: (1) have a DB pension + State Pension covering essential expenses, (2) want to leave money to heirs (annuities die with you), (3) can tolerate investment volatility. Many retirees use both — annuitise enough to cover essentials, drawdown the rest.

The 25% tax-free lump sum trap. Many retirees withdraw their 25% PCLS at retirement and then annuitise. This is often suboptimal: cash earns less than the annuity rate, and the lump sum is then exposed to inheritance tax. An alternative: take the 25% gradually through UFPLS (Uncrystallised Funds Pension Lump Sums) over many years to spread tax-free benefits, or buy a 'with-profits' annuity from your full pot for maximum income. The 25% lump sum is now capped at £268,275 (the Lump Sum Allowance) after the 2023 abolition of the Lifetime Allowance.

What is an annuity? Insurance product: you give a lump sum from your pension, the provider guarantees regular income for life (or a specified term). UK annuity rates 2026: roughly £62-£68/year per £1,000 at age 65 (6.2-6.8%). £100,000 pension pot = ~£6,200-£6,800/year guaranteed income for life, regardless of how long you live. Annuities lost favour after 2015 Pension Freedoms — only ~10% of retirees now buy them (vs 90% pre-2015). Best for: those wanting guaranteed income, no inheritance plans, average/poor health.

Types of UK annuity. Single-life level: highest income, dies with you (worst for surviving spouse). Joint-life: pays surviving spouse 50-100% — lower starting income. Escalating: income rises 3-5%/year or RPI/CPI-linked — much lower starting income. Enhanced/impaired-life: higher rates if you smoke, have diabetes, heart condition, BMI 30+ — sometimes 20-40% higher income. Fixed-term: pays for set period (5-15 years), then lump sum back. Investment-linked: variable income based on fund performance — gamble for higher upside.

Annuity vs drawdown — which is better? Annuity: predictable, no investment risk, no decisions to make, dies with you (unless joint). Drawdown: keep pension invested, take income as needed, can pass to family on death. Crossover age (when drawdown becomes riskier than annuity): typically late 70s-80s — at that point annuity rates ~10%+ become hard to beat with safe investments. Best practice: drawdown in early retirement (active years), buy annuity in later years (less mental capacity for investment decisions).

How to shop for the best annuity rate. NEVER take the rate from your current pension provider without comparison — typically 10-30% worse than open-market rate. Use 'Open Market Option' (legal right since 1980s): take pension lump sum to ANY annuity provider. Top UK annuity providers 2026: Just, Canada Life, Legal & General, Aviva, Standard Life. Compare via: MoneyHelper (free, government-backed), annuity broker (commission paid by provider, often free to you), MoneySavingExpert. Disclose all health conditions and lifestyle factors — even minor ones increase rate.

Tax treatment of annuity income. Annuity income taxed as income tax (PAYE). Within personal allowance £12,570: 0% tax. Higher: 20%/40%/45% bands. Tax-free 25% lump sum: take BEFORE buying annuity (within £268,275 lump sum allowance). £100k pension: take £25k tax-free, £75k buys annuity. £75k × 6.5% = £4,875/year annuity income. State Pension + annuity together: must stay under personal allowance to avoid tax. Spouse benefit on death: continues to be taxable income for survivor. No inheritance tax on annuity itself (income stream, not asset).
