Pension Calculator UK (2026/27)

This UK pension calculator helps you model how your retirement savings could grow over time. You can project your future pot, test the impact of higher contributions, estimate the fund needed for a target retirement income and explore a simple drawdown illustration.

It is designed for UK savers who want a practical planning tool that combines private pension growth, employer contributions, inflation assumptions and retirement income estimates in one place.

What this calculator includes

  • Current pension pot and future contribution projections
  • Employee and employer contributions
  • Salary growth, investment growth and annual charges
  • Inflation-adjusted planning
  • Optional State Pension and DB pension inputs
  • Target income and drawdown illustrations

How it works

The calculator starts with your current pension balance, then adds future contributions and applies growth assumptions over time. It also adjusts for charges and can show inflation-aware results so you can compare nominal and real-world purchasing power more clearly.

Depending on the mode you use, it can also estimate the effect of raising contributions, the pension pot needed for a chosen retirement income, or what a simple drawdown path might look like once you stop working.

Why your results may be different

Pension outcomes can vary significantly in real life. Actual results depend on investment returns, fees, salary changes, contribution gaps, retirement timing, inflation and how your chosen pension scheme works.

  • Investment growth is uncertain and will not be smooth year to year
  • Charges, fund selection and employer rules can change outcomes materially
  • State Pension entitlement may differ from a simple full-rate assumption
  • Drawdown sustainability depends on returns, withdrawals and longevity

Who it’s for

  • Workers checking whether current pension contributions are enough
  • People comparing different retirement ages or contribution rates
  • Savers estimating the pot needed for a target income
  • Anyone building a rough retirement plan before taking advice

Pension examples

  • A 30-year-old increasing contributions from 5% to 8% can materially improve their projected retirement pot over the long term.
  • A saver with a £50,000 pension pot and regular employer contributions may see strong compounding over 25 to 30 years.
  • Someone planning to retire earlier may need either a larger pot or a lower target income to keep drawdown sustainable.

Important note

This calculator provides estimates only and does not constitute financial, tax or legal advice. Pension planning decisions can be significant, and regulated financial advice may be appropriate for retirement, transfer or drawdown decisions.

Pension calculator FAQs

There is no single right number. It depends on your target retirement income, when you want to retire, whether you have other assets, and how much State Pension or DB pension income you expect.

Yes. You can include both employee and employer contributions, which is important because employer payments can make a major difference over time.

It can. The calculator allows you to include a State Pension assumption, but your actual entitlement depends on your National Insurance record and the rules that apply when you retire.

It is a planning estimate, not a guaranteed forecast. Long-term returns, inflation, charges and contribution changes can all shift the final outcome.

A lower withdrawal rate is generally more cautious, but there is no universally safe figure. Sustainability depends on investment returns, inflation, taxes, life expectancy and how flexible your spending is.

Often yes. Even relatively small increases can compound over many years, especially when combined with employer contributions and tax relief.

It includes some DB inputs for planning, but DB schemes can be more complex. Scheme-specific rules, accrual terms and revaluation methods can differ, so the output should be treated as a broad estimate.
