Worked example
Overall, £200k could fund £15k a year — but split as a pension plus a smaller ISA, too much of it is locked away at 51: the accessible savings run dry around age 53, before the pension can be drawn at 55. A bigger ISA or cash bridge, or a slightly later date, closes the gap.

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.
At 51 you’re 4 years short of 55, the earliest you can normally draw a private or workplace pension (rising to 57 in April 2028). Those years have to come from the £40,000 ISA-and-savings slice, not the pension.
In this scenario the accessible savings run dry around age 53, before the pension unlocks — the bridge, not the pension, is what limits retiring this early. A larger ISA slice, a later date, or part-time income for the first few years is what closes it.
Until 67 every pound of the £15k-a-year lifestyle comes from your own savings. Once the full State Pension (£12,548) starts, it covers a chunk of that.
The amount you draw from savings drops from about £15,608 in the year before to £3,060 after — roughly £12,548 a year less pressure on the pot for the rest of retirement.
Even at £15k a year — the lowest level we tested — £200k runs short around age 53 on these assumptions.
Because you're retiring before 55, the squeeze comes early. Realistically this needs a bigger pot, a later start, or part-time income to bridge the first stretch.
The same pot, retiring at 51, tested from £15k to £60k of annual spending.
| Annual spending | Verdict | Money lasts | Left at 95 |
|---|---|---|---|
| £15,000 | Bridge gap | Bridge gap at 53 | £41,166 |
| £20,000 | Runs short | Runs out at 65 | £0 |
| £30,000 | Runs short | Runs out at 61 | £0 |
| £40,000 | Runs short | Runs out at 59 | £0 |
| £50,000 | Runs short | Runs out at 58 | £0 |
| £60,000 | Runs short | 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 | £193,000 |
| 56 | £15,000 | £0 | £15,608 | £170,612 |
| 61 | £15,000 | £0 | £15,608 | £123,040 |
| 66 | £15,000 | £0 | £15,608 | £65,162 |
| 71 | £15,000 | £12,548 | £3,060 | £62,708 |
| 76 | £15,000 | £12,548 | £3,060 | £59,723 |
| 81 | £15,000 | £12,548 | £3,060 | £56,090 |
| 86 | £15,000 | £12,548 | £3,060 | £51,671 |

Every year is funded, but the savings carrying you to pension access get down to £5,570 at age 54 — less than a year's withdrawals
Overall, £200k could fund £15k a year — but split as a pension plus a smaller ISA, too much of it is locked away at 51: the accessible savings run dry around age 53, before the pension can be drawn at 55. A bigger ISA or cash bridge, or a slightly later date, closes the gap. These figures assume £200k split as £160k in a pension and £40k in an ISA, £12,548 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.
