Worked example
Can I retire at 35 with £100k?
On its own, £100k split as a pension plus a smaller ISA doesn't stretch far enough to retire at 35: even on £15k a year the accessible savings run dry around age 36, before the pension can be drawn at 55. You'd need a bigger bridging pot, a later date, or more guaranteed income.

The example we modelled
A single person retiring at 35 today with a £100k pot, split so the pension is the bulk of the money. All figures are in today’s money (real terms).
The result at £15k a year
Even the lowest spending level we tested runs short — here is what that looks like.
How far £100k stretches at different spending levels
The same pot, retiring at 35, tested from £15k to £60k of annual spending.
| Annual spending | Verdict | Money lasts | Left at 95 |
|---|---|---|---|
| £15,000 | Run-out | Runs out at 36 | £290,628 |
| £20,000 | Run-out | Runs out at 70 | £0 |
| £30,000 | Run-out | Runs out at 62 | £0 |
| £40,000 | Run-out | Runs out at 60 | £0 |
| £50,000 | Run-out | Runs out at 58 | £0 |
| £60,000 | Run-out | Runs out at 57 | £0 |
Year-by-year projection at £15k a year
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 |
|---|---|---|---|---|
| 35 | £15,000 | £0 | £15,000 | £90,000 |
| 40 | £15,000 | £0 | £0 | £107,208 |
| 45 | £15,000 | £0 | £0 | £136,827 |
| 50 | £15,000 | £0 | £0 | £174,630 |
| 55 | £15,000 | £0 | £15,608 | £207,270 |
| 60 | £15,000 | £0 | £15,608 | £178,293 |
| 65 | £15,000 | £0 | £15,608 | £141,311 |
| 70 | £15,000 | £11,502 | £4,106 | £143,686 |

Frequently asked questions
Can I retire at 35 with £100k?
On its own, £100k split as a pension plus a smaller ISA doesn't stretch far enough to retire at 35: even on £15k a year the accessible savings run dry around age 36, 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 £100k split as £80k in a pension and £20k in an ISA, £11,502 of State Pension from age 67, and around 5% investment growth a year above inflation.
How much can I spend a year if I retire at 35 with £100k?
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.
Can I access my pension at 35?
Not yet. The earliest you can normally take a private or workplace pension is age 55 (rising to 57 in April 2028). Retiring at 35 means bridging the 20 years until then from ISAs and other savings — which is why the ISA slice of the pot matters so much at this age.
Are these numbers financial advice?
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.
