Retirement Income Calculator UK

The Retirement Income Calculator estimates the income you could receive from pensions and other retirement resources. It can help you combine income from a defined contribution pension, State Pension, defined benefit schemes and any other amounts included in the calculator.

The result is an illustration rather than a guaranteed retirement income. Investment performance, withdrawal choices, annuity rates, inflation, tax, charges and the date each income begins can materially change the amount available.

How does the Retirement Income Calculator work?

The calculator combines the retirement income sources entered and, where applicable, estimates an income from a pension pot. Its result depends on the withdrawal, growth and timing assumptions shown by the tool.

Enter the information requested by the calculator. Depending on the available fields, this may include a defined contribution pension pot, intended retirement age, assumed withdrawal rate, State Pension, defined benefit pension and other regular retirement income.

The calculator may estimate income from a pension pot using a calculation such as:

Pension pot × assumed annual withdrawal rate = illustrative annual pension income

It then adds any other retirement income entered. Where monthly or weekly figures are displayed, these are normally conversions of the annual estimate rather than separate benefit calculations.

Check whether the tool treats income as gross or net, whether State Pension is entered manually and whether investment growth or charges are included. Do not assume that an income source is included unless it appears in the calculator’s inputs or results.

What do the retirement income results mean?

The total retirement income is the combined annual amount produced under the assumptions entered. It may be shown before tax and does not confirm that the income will continue for life.

Defined contribution income is an estimate based on the pension pot and withdrawal assumption. It is not guaranteed unless the fund is used to buy an annuity or another product providing contractual income.

Defined benefit income is usually based on scheme rules, pensionable service and earnings. Use an up-to-date scheme quotation because taking benefits early, exchanging pension for a lump sum or choosing dependant protection can alter the amount.

State Pension income should come from your personal forecast. The full new State Pension is £241.30 per week for 2026/27, but individual entitlement can be higher or lower depending on the National Insurance record and transitional rules.

The monthly result is usually the annual figure divided by 12. State Pension itself is commonly paid every four weeks, so actual cash-flow dates may differ from a monthly illustration.

Illustrative retirement income calculation

This illustrative example combines three retirement income sources using simplified assumptions. It does not guarantee that the pension pot can support the selected withdrawal for life.

Illustrative assumptions: a person retires at 67 with a £300,000 defined contribution pension, a defined benefit pension of £6,000 a year and the full 2026/27 new State Pension. They model withdrawals equal to 4% of the defined contribution pot in the first year.

Income source	Illustrative calculation	Annual gross income
Defined contribution pension	£300,000 × 4%	£12,000.00
Defined benefit pension	Scheme quotation	£6,000.00
New State Pension	£241.30 × 52 weeks	£12,547.60
Total estimated income	Combined gross income	£30,547.60

The estimated monthly equivalent is approximately £2,545.63 before tax. Actual payments may arrive on different dates, and the State Pension and private pension components may not increase at the same rate.

The 4% withdrawal is an illustrative assumption rather than a recommended or guaranteed sustainable rate. Poor investment performance, higher charges or increasing withdrawals could reduce the defined contribution fund more quickly.

Which income sources should be included?

Include only income that is reasonably expected and use the correct start date for each source. Income beginning later should not be treated as available from the first day of retirement.

State Pension: use the amount and eligibility date from your official forecast.
Defined contribution pensions: include only pots intended to provide retirement income.
Defined benefit pensions: use the scheme’s estimate for the age at which benefits will be taken.
Annuities: use a current quotation reflecting options such as inflation protection and dependant benefits.
Employment or self-employment: include part-time earnings only for the period they are expected to continue.
Property income: use net income after realistic expenses, tax and periods without rent.
Savings and investments: distinguish regular income from withdrawals that reduce capital.
Other benefits: check eligibility and whether pension income or capital affects entitlement.

A retirement beginning before State Pension age may have distinct phases. Private savings might provide most income initially, with State Pension and defined benefit payments beginning later.

How is retirement income taxed?

State Pension, defined benefit payments, annuity income and taxable private pension withdrawals generally count as taxable income. Eligible pension lump sums may be tax free within the applicable allowance.

The State Pension is taxable but normally paid without tax being deducted. HMRC may collect tax attributable to it through the PAYE code applied to another pension, or through a separate calculation where necessary.

Private pension and annuity providers normally deduct Income Tax through PAYE. Your final liability depends on total income, tax code, residence and other circumstances. Scottish Income Tax bands can apply to pension income where the individual is a Scottish taxpayer.

You can usually take up to 25% of qualifying pension benefits tax free, subject to your remaining lump sum allowance. The standard lump sum allowance is £268,275 for 2026/27, although previous withdrawals and protected allowances can change the amount. GOV.UK explains the current pension lump sum allowance.

Taking tax-free cash reduces the amount remaining to generate future income. For example, taking £75,000 from a £300,000 pension would leave £225,000 invested before any growth, losses, charges or further withdrawals.

National Insurance is not normally charged on pension income. Earnings from employment or self-employment can still have separate National Insurance consequences before the individual reaches State Pension age.

How much State Pension should be entered?

Use your personal State Pension forecast rather than automatically entering the full rate. Qualifying years, contracting out and the pre-2016 transition can change entitlement.

The full new State Pension is £241.30 per week for 2026/27, equivalent to £12,547.60 over 52 weeks. This applies as the standard full rate for people reaching State Pension age under the new system, but it is not guaranteed to every claimant.

People with no National Insurance record before 6 April 2016 normally need 35 qualifying years for the full rate and at least 10 for any new State Pension. Records extending before April 2016 can require a transitional starting-amount calculation.

Check the official State Pension forecast for the amount you may receive and the date it can start. The forecast is more reliable than estimating entitlement solely from the number of qualifying years.

How can a pension pot produce retirement income?

A defined contribution pension can provide income through drawdown, an annuity, lump-sum withdrawals or a combination of methods. Each option has different guarantees, risks, tax treatment and charges.

Flexi-access drawdown

Drawdown keeps the remaining pension invested while allowing flexible withdrawals. Income can be adjusted, but investment losses and high withdrawals can cause the fund to fall or run out.

Lifetime annuity

An annuity uses pension money to purchase an income under agreed terms. The income may be guaranteed for life, but the amount depends on market rates, age, health and options such as inflation increases or payments to a surviving partner.

Cash withdrawals

Some or all of a pension can be taken as cash where provider and tax rules permit. Large taxable withdrawals can move income into higher tax bands and leave less money for later retirement.

Combination approach

Part of the pension can provide secure income while the remainder stays invested or available for flexible withdrawals. The appropriate balance depends on spending needs, risk tolerance and other guaranteed income.

GOV.UK outlines the available options for taking money from a personal pension.

Is the estimated retirement income sustainable?

A calculated first-year income is not necessarily sustainable for the remainder of retirement. Sustainability depends on withdrawals, investment returns, inflation, charges and how long income is required.

Withdrawal rate: higher withdrawals use the pension pot more quickly.
Sequence of returns: investment losses early in retirement can have a disproportionate effect.
Inflation: fixed income loses spending power, while increasing withdrawals places more pressure on the fund.
Charges: fund, platform, transaction and adviser fees reduce the return retained.
Longevity: retirement income may be needed for longer than expected.
Asset allocation: investment risk and return potential depend on the assets held.
Unexpected spending: repairs, family support and care costs can require additional withdrawals.
Income changes: State Pension, defined benefit pensions or employment income may begin or end later.

Compare more than one scenario. Testing lower investment returns, higher inflation, longer retirement and greater spending can show whether the plan has any margin for adverse outcomes.

How does inflation affect retirement income?

Inflation reduces what a fixed amount can buy over time. A useful calculation should distinguish between future cash amounts and values expressed in today’s money.

An income of £30,000 in a future year may not provide the lifestyle that £30,000 supports today. If inflation averaged 2.5%, maintaining the same purchasing power would require income to rise over time.

Some defined benefit pensions and annuities increase under their terms, but increases may be capped or apply differently to separate parts of the benefit. State Pension uprating follows government policy and legislation, which may change during a long retirement.

Increasing drawdown withdrawals with inflation can help maintain spending power but also raises the risk that the pension fund is depleted sooner.

Common retirement income mistakes

Common mistakes include treating gross income as spendable income, entering the full State Pension without checking entitlement and assuming a pension withdrawal rate is guaranteed. Start dates and inflation should also be handled consistently.

Adding income sources that begin at different ages as though they all start immediately.
Comparing gross pension income with a household budget based on net spending.
Using the full State Pension rate without obtaining a personal forecast.
Counting a tax-free lump sum as recurring annual income.
Ignoring charges or using an investment return before fees where a net rate is required.
Assuming a defined benefit pension will be unreduced when taken early.
Treating an illustrative drawdown rate as guaranteed for life.
Ignoring inflation, care costs or a surviving partner’s future income needs.
Double-counting income already included in another pension estimate.

Important limitations of the calculator

The calculator cannot predict investment returns, annuity rates, inflation, lifespan, tax-code changes or future pension law. Its results should be treated as planning illustrations based on the information entered.

The calculation may not include tax, provider charges, protected pension ages, existing use of lump sum allowances, inherited pensions or benefit interactions unless these are expressly included in the tool.

Defined benefit and State Pension amounts should be taken from official or provider forecasts. An estimate based solely on current rates may not reflect individual entitlement, early-retirement reductions or scheme-specific increases.

Use the Income Tax Calculator for broader tax context, the Compound Interest Calculator for long-term growth modelling and the Pension Annual Allowance Calculator when checking contribution limits.

This calculator provides estimates only. Actual pension income, investment returns, tax treatment, personal circumstances and available reliefs differ, and pension or tax rules may change; regulated financial advice or appropriate professional tax advice may be suitable before making retirement-income decisions.
