A first house at 26, two children in the thirties, and stopping work somewhere between 60 and 65. Every figure here is in today's money, so inflation is already stripped out.
On two years averaging £80,000 to £100,000 net profit, filed after August 2027, borrowing capacity clears what the house needs with room to spare. Contributing to the pension does not change that.
| Scenario | Assessed income | At 4.5x | At 5x |
|---|---|---|---|
| No pension contribution | £102,570 | £461,565 | £512,850 |
| After £20,000 into the pension | £82,570 | £371,565 | £412,850 |
| What a £350,000 house needs at 10% down | — | £315,000 | £315,000 |
Order matters. Each phase has one thing it is uniquely good at, and one thing that stops being possible once it ends.
Everything points at the house. The Vanguard ISA de-risks in tranches into a money market fund, the LISA collects its second £1,000 bonus in April 2027, and the pension stays untouched so FY27 profit reads clean for a lender.
Mortgage settled, no children, business at full margin. This is the highest surplus you will ever have relative to your commitments, and it lasts about four years. Money invested here compounds for thirty more. Every pound you skip now costs roughly four pounds at 60.
A child costs about £250,000 to eighteen for a couple, including housing. Two overlapping means a peak of roughly £25,000 a year through the mid thirties. Contributions dip and that is fine, because phase two did the heavy lifting.
Two things become non-optional the moment a child exists. Life insurance and a will, and income protection, because Hunt Visuals stops earning the day you do.
School years, business mature, costs plateauing. On every track modelled, the £1,020,000 target is passed in this decade or before it. From here you are working because you want to, not because the sum requires it.
Children independent, mortgage most likely cleared around age 51. Pension access opens at 57 or 58. The last decade is about de-risking, moving out of pure equities as the date approaches, not accumulating more.
Both wrappers grow tax free. The difference is not what happens inside them, it is what the money goes through to get in.
The taxman takes his cut before an ISA and after a pension. Taking it after means the whole amount compounds for 36 years first.
| Route for £15,000 | Company profit needed | Value at 60 | After withdrawal tax |
|---|---|---|---|
| ISA, higher rate dividend | £31,764 | £144,770 | £144,770 |
| Pension, same £31,764 | £31,764 | £306,561 | £260,577 |
| ISA, basic rate dividend | £22,866 | £144,770 | £144,770 |
| Pension, same £22,866 | £22,866 | £220,689 | £187,586 |
| Growth assumption | £60,000 a year at | Pot at 50 | Pot at 60 | Pot at 65 |
|---|---|---|---|---|
| 6.5 percent real | age 50 | £1.46m | £2.97m | £4.15m |
| 5 percent real | age 55 | £1.11m | £2.00m | £2.64m |
The S&P 500 returned 10.0 percent nominal and 6.9 percent real annualised from 1928 to 2025 with dividends reinvested. Take off Vanguard's platform and fund charges and 6.5 percent is the honest planning figure. It is also a dollar figure and the best century any equity market has ever had, which is why the five percent line is on the chart.
A forty percent fall at 58 does far more damage than the same fall at 28, because there is no time and no new money buying the recovery. That is what phase five de-risking is for.
Two state pensions, shared housing, shared child costs. Published couple figures are materially less than double the single ones, so this plan is deliberately the pessimistic version.
Only the rise to 57 in April 2028 is law. Beyond that, policy intent is roughly ten years below state pension age. Worst realistic case costs one or two years, which the ISA half of the split covers.
From 6 April 2027, interest on cash held inside a stocks and shares ISA is charged at 22 percent. Whether a money market fund counts as cash for this is not clear and it affects both the deposit de-risking and the LISA. The exposure is small, roughly £100 to £175 a year, but it needs confirming.
Buy a home for a penny over £450,000 and the whole Lifetime ISA withdrawal takes a twenty five percent charge, destroying roughly £3,300. With capacity possibly at £560,000 this is reachable for the first time.
A sale is the most likely route to finishing far earlier than any track here. It is also illiquid, depends on Lloyd personally, and may be worth nothing. Upside, never the plan.
