Fixed Term Annuity Calculator (UK)
Estimate your regular income from a fixed term annuity and the amount left at maturity.
Assumption: level payments over the term. This is an educational estimate, not a personal recommendation.
What is a fixed term annuity in the UK?
A fixed term annuity is a retirement income product that pays you a guaranteed income for a set number of years (for example, 3, 5, or 10 years), instead of for life. At the end of the term, you usually receive a maturity value that can be used to buy another annuity, move into drawdown, or take pension benefits under the rules in force at the time.
Many people like fixed term annuities because they provide certainty for a period while keeping future options open. If rates improve later, you may benefit when the term ends and you shop around again.
How this UK fixed term annuity calculator works
This calculator uses a standard annuity formula to estimate regular income based on:
- the amount invested from your pension pot,
- the term length in years,
- an assumed annual rate,
- your selected payment frequency, and
- any guaranteed maturity value retained for the end of the term.
If you set a higher maturity value, regular income will usually be lower because more value is being preserved for the end date. If you reduce the maturity value, regular income can be higher.
Inputs explained
- Pension pot used: The amount allocated to purchase the fixed term annuity.
- Tax-free cash upfront: Up to 25% is commonly available from UK defined contribution pensions before buying income.
- Term length: The guaranteed payment period.
- Illustrative annual rate: Used to project payments; this is not a guaranteed market quote.
- Guaranteed maturity value: Amount expected at the end of term.
- Payment frequency: Monthly, quarterly, or annual income.
- Estimated tax rate: For a rough net income estimate (actual tax depends on your full income situation).
Example: quick interpretation
Suppose you invest £100,000 for 10 years with a 4.25% illustrative rate and keep a £20,000 maturity value. You’ll get an estimated regular income plus the final maturity amount. If you increase the maturity value to £30,000, your periodic income should fall. If you reduce it to £10,000, periodic income should rise.
This is a useful way to test trade-offs between spending now and preserving flexibility later.
Fixed term annuity vs lifetime annuity vs drawdown
Fixed term annuity
- Income guaranteed for a set period only.
- Maturity value can provide future flexibility.
- Useful when you expect your plans or rates to change.
Lifetime annuity
- Income generally guaranteed for life.
- No investment management required by you.
- Less flexibility once purchased.
Flexi-access drawdown
- Your pension remains invested, so value can rise or fall.
- High flexibility in withdrawals.
- Requires ongoing monitoring and withdrawal discipline.
Tax points UK retirees should remember
- Usually, up to 25% of pension benefits can be taken tax-free (subject to current legislation and personal limits).
- Most annuity income is taxable as earned income.
- Your Personal Allowance, other income, and tax bands affect net income.
- Emergency tax may apply initially to some pension payments and then be corrected.
How to use this calculator effectively
- Start with your realistic pension amount.
- Try multiple term lengths (e.g., 5, 7, 10 years).
- Compare low, medium, and high rate assumptions.
- Test different maturity values to see income trade-offs.
- Review gross and estimated net figures before deciding what is affordable.
Limitations of any online annuity calculator
No calculator can fully replace an insurer quote or personalised financial advice. Real pricing depends on provider terms, age, health, options selected, and market conditions at the time you apply.
Use this as a planning tool, then compare live quotes and seek regulated advice if needed.
