Worked example
On its own, £200k split as a pension plus a smaller ISA doesn't stretch far enough to retire at 51: even on £15k a year the accessible savings run dry around age 53, before the pension can be drawn at 55. You'd need a bigger bridging pot, a later date, or more guaranteed income.

A single person retiring at 51 today with a £200k pot, split so the pension is the bulk of the money. All figures are in today’s money (real terms).
Even the lowest spending level we tested runs short — here is what that looks like.
The same pot, retiring at 51, tested from £15k to £60k of annual spending.
| Annual spending | Verdict | Money lasts | Left at 95 |
|---|---|---|---|
| £15,000 | Run-out | Runs out at 53 | £159,178 |
| £20,000 | Run-out | Runs out at 67 | £0 |
| £30,000 | Run-out | Runs out at 61 | £0 |
| £40,000 | Run-out | Runs out at 59 | £0 |
| £50,000 | Run-out | Runs out at 58 | £0 |
| £60,000 | Run-out | Runs out at 57 | £0 |
Projected balances every five years, in today’s money. Spending includes your State Pension once it starts at 67, so the amount drawn from your savings drops from then on.
| Age | Spending | State Pension | Drawn from savings | Pot value |
|---|---|---|---|---|
| 51 | £15,000 | £0 | £15,000 | £195,000 |
| 56 | £15,000 | £0 | £15,608 | £182,420 |
| 61 | £15,000 | £0 | £15,608 | £146,578 |
| 66 | £15,000 | £0 | £15,608 | £100,833 |
| 71 | £15,000 | £11,502 | £4,106 | £106,006 |
| 76 | £15,000 | £11,502 | £4,106 | £112,608 |
| 81 | £15,000 | £11,502 | £4,106 | £121,035 |
| 86 | £15,000 | £11,502 | £4,106 | £131,789 |

Your pot keeps growing right to the end
On its own, £200k split as a pension plus a smaller ISA doesn't stretch far enough to retire at 51: even on £15k a year the accessible savings run dry around age 53, before the pension can be drawn at 55. You'd need a bigger bridging pot, a later date, or more guaranteed income. These figures assume £200k split as £160k in a pension and £40k in an ISA, £11,502 of State Pension from age 67, and around 5% investment growth a year above inflation.
Even £15k a year runs short before age 95 on these assumptions. The table shows exactly when the money runs out at each spending level — you'd need lower spending, more income, or a later retirement date to close the gap.
Not yet. The earliest you can normally take a private or workplace pension is age 55 (rising to 57 in April 2028). Retiring at 51 means bridging the 4 years until then from ISAs and other savings — which is why the ISA slice of the pot matters so much at this age.
No. This is an illustrative worked example from a free planning tool, using fixed assumptions about growth, inflation, tax and the State Pension. Your own situation — other pensions, a partner, different returns — will change the answer. Open the planner to run it with your real figures.
