Reading time: 10 minutes

Many people now plan for their savings to last to age 95 or beyond. A 65-year-old in the UK has a roughly one-in-four chance of living that long, and running short late in life is hard to recover from. Enter your figures to see an illustrative projection of how long your savings might last. You can change the planning age to suit you. The results depend on assumptions set out in "How we got these figures." They aren't a prediction or financial advice.

Run it on your whole financial picture

Enter your figures once in My Money and every calculator uses them, from income tax to inheritance tax, alongside a year-by-year cashflow plan.

  • Saved onceYour pension pot, salary and spending carry across every tool.
  • Projected forwardSee how today's decision plays out year by year to retirement.
  • Checked for youInsights flag allowances and reliefs you haven't used.

Can I retire yet?

How long your pot could sustain your target lifestyle, including an estimate of the tax you'd pay along the way. We show the numbers, we don't give advice.

1. Your money

SIPPs, workplace pensions, and any other pension savings.

ISAs, GIAs, savings accounts. ISA withdrawals are tax-free.

What you'd like to spend each month after tax.

2. Other income

Paid every 4 weeks. Full new State Pension is approx. £965 every 4 weeks from State Pension age.

Rental income, part-time work, purchased annuities etc. (Defined Benefit pensions are handled separately below.)

Total guaranteed annual income across all your Defined Benefit pensions, once in payment.

If you have more than one Defined Benefit pension, the earliest start age across them.

3. Your situation

Annual return before inflation, converted to a real (inflation-adjusted) rate internally using the assumption below, so everything else (spending, State Pension, tax bands) can stay in today's money throughout.

Used to convert investment growth to a real rate. Spending, State Pension, Defined Benefit income, and tax thresholds are all modelled in today's money; none of them are separately uprated.

An estimate for guidance and education, not regulated financial advice. Open Retirement Runway in the app to keep your figures and use them across the other calculators.
