Any shortfall in day-to-day spending is covered automatically — from the ISA at any age, and from the Pension from retirement age onward (reflecting real UK pension access rules) — there's no need to work out withdrawal amounts by hand. Each pot (General, ISA, Pension) can be given its own growth rate, reflecting how differently they might be invested.
Growth and withdrawals are always tax-free. Contributions and withdrawals move to and from the opening balance above, in today's money. Leave this section blank if the client doesn't have an ISA.
Money going into the ISA — e.g. £5,000/year while working. Each period can optionally step up year on year — e.g. contributions rising with a growing salary — using the annual growth rate and cap fields; leave both blank for a flat amount, as before.
Only for money the client knows in advance they'll take out — a one-off need such as a wedding, at any age. Day-to-day spending is covered automatically, on top of this, so there's no need to enter it here.
Contributions are entered as what's actually paid in (net) — basic-rate tax relief is added automatically. Withdrawals aren't entered directly: once retirement spending begins, the amount needed is worked out automatically, using up the tax-free cash allowance (up to £268,275 over a lifetime) before anything becomes taxable — and any taxable withdrawal is taxed together with the client's other income that year, not on its own. Leave this section blank if the client doesn't have a pension.
What's actually paid in — e.g. £8,000/year while working. Basic-rate tax relief is added automatically; higher and additional-rate relief aren't included, since that depends on a separate claim. Each period can optionally step up year on year — e.g. contributions rising with a growing salary — using the annual growth rate and cap fields; leave both blank for a flat amount, as before.
This defaults to the current full new State Pension — edit it if the client's situation differs. It's taxed like other income, though National Insurance never applies to it. The full amount happens to sit just under the tax-free Personal Allowance, so a client relying on State Pension alone would pay no tax on it.
Leave a stage blank if it doesn't apply to this client. Enter gross amounts, before tax — income tax is worked out automatically each year across all ongoing income, and National Insurance is added on top of the Current Lifestyle stage specifically, since that represents earnings from work. One-off items below aren't taxed. Each stage can optionally grow year on year — e.g. a salary that's still climbing — using the annual growth rate and cap fields; leave both blank for a flat amount, as before.
Employment income and other earnings before retirement.
Pension income, part-time work, or other income while still active.
Income during the later, less active retirement years.
Lump sums received — an inheritance, a redundancy payout, proceeds from a sale. These aren't taxed.
Leave a stage blank if it doesn't apply to this client. Each stage can optionally grow year on year — e.g. the cost of living rising alongside a growing income — using the annual growth rate and cap fields; leave both blank for a flat amount, as before.
Everyday living costs before retirement, while still working.
The years you're fit and active enough to make the most of retirement — often the highest-spending phase.
Once you've slowed down and become less active — spending typically eases here.
Individual lump sums — a wedding, a car, a home renovation, a gift.
Optional tools for testing how a plan holds up under different conditions — gradually de-risking a portfolio over time, an unexpected spell of inflation, or a market downturn.
Gradually shifts a pot from its growth rate above to a more defensive rate as retirement approaches, rather than assuming one flat rate for the whole plan. Off by default. Each pot can be de-risked on its own schedule — a client might reduce risk in their Pension years before touching their ISA.
Defaults to the Bank of England's 2% inflation target. Income, expenditure, and State Pension amounts rise with inflation each year; investment growth is shown before adjusting for it.
Optional — add a temporary period of higher or lower inflation on top of the rate above, e.g. "8% from age 66 to 68". If periods overlap, the earliest one entered takes priority.
Model a market crash or financial crisis — a period where investment growth turns negative, overriding the usual rate for that time. A downturn early in retirement can do lasting damage, since money is being drawn from a pot that's shrunk rather than left to recover. Optional — leave this empty if there's no crash to test.
e.g. "−20% from age 68 to 69" to model a downturn like 2008. Applies equally to General, ISA, and Pension. If periods overlap, the earliest one entered takes priority.
