How much is enough?

A simple way to think about the capital that may support the life you want — worked out in plain English, privately, in your browser.

What does “enough” look like for you?

Use today’s money, for one person or one household. The figures shown are examples — replace them with your own. You can type amounts like 60,000 or 800k.

1 · When the money is needed
When do you want this money to start supporting your lifestyle?
2 · The life you want

3 · What you already have

4 · Income that starts later optional

For example, a State Pension or final salary pension that starts after your money is first needed.

Later-life support and care reserve
An optional amount set aside for additional support or care in later life. Use today’s money. This is not an estimate of what care will cost. Exclude costs already included in your annual spending or other reserves.
6 · Your assumptions
%

This is an illustrative target, not a forecast. It divides your long-term yearly gap by the withdrawal rate, then adds a bridge reserve for any extra gap before later income starts, and any amounts you set aside. It does not test whether withdrawals will last, and it does not model investment growth, future saving, inflation, charges, market falls or how long you will live. It treats your income as keeping pace with prices; some pensions and annuities do not. Tax is not calculated: income is entered before tax, so your spending figure should include an allowance for tax. Withdrawals from savings, investments and pension pots are not guaranteed. Its purpose is to start a conversation, not to finish one.

How this was worked out

What if your money needs to last until 90, 95 or 100?

This calculator does not test how long your withdrawals will last. Average life expectancy is only an average — many people live well beyond it, so it is not a safe end date for a plan.

If you are planning as a couple, think about what the surviving partner will need. Household income may fall when one person dies, while many costs stay much the same.

For a sense of the ages you might reach, the Office for National Statistics has a life expectancy calculator (opens in a new tab).

Enough is more than a number

The number is a starting point. The harder question is what you want your money to do for you.

  • What would a good year look like, if money were not the worry?
  • Who and what matters most — and does your spending reflect that?
  • If you already have enough, what are you still working towards?

We will explore what is happening across your financial life, what feels disconnected, and whether Sustain Momentum could help you bring the whole picture together.
