How do you want to set your allocation?
The Decision Tool works from your real portfolio. Add your holdings — each is tagged to a bucket and sub-class (change any of them). Your target allocation updates automatically as you add, edit or remove funds.

When on, the Decision Tool's monthly withdrawal and rebalancing advice follows this rising-equity path, and each year's report tells you the target mix to hold.
Spending need
Locked with the plan. "Declining" is level for the first 5 years, then drifts down ~1%/yr for
20 years, then holds — the same spending smile as the Stress tester. In those declining years the
April wizard nets the drop off the inflation uplift (e.g. CPI 2.5% − 1% = a 1.5% target rise).
Protection Mode: Triggers after consecutive cash draws. Reduces withdrawal by the protection factor until growth funds recover above minimums + recovery buffer.

Carves a slice into assets that tend to hold up or rise when shares fall. Tail protection, not a free lunch — run it and compare.

Holds least in shares when the pot is largest and most exposed to an early crash, then raises shares once that danger passes (Pfau-Kitces). Typically helps the worst cases but can slightly lower typical growth — run it and compare. Your risk level stays the average.
Glidepath: Equity & Bond minimums inflate with CPI but deplete linearly to £0. Cash inflates only (maintains real value).
Tax thresholds (year 0)
SIPP Calculation: SIPP Draw = Target Income - Other Pensions - State Pension
(But never more than the Basic Rate Limit, to avoid 40% tax)
Other income (year 0)
State Pension
Pension Inflation:
• Other Income/Pension: Follows CPI, capped at 4% per year
• State Pension: Follows CPI (triple-lock proxy)
ISA

Break Glass Reserve: Emergency fund only accessed when main strategy would otherwise fail.
Spending
Real spending typically falls through retirement (Blanchett's "spending smile"). "Declining" holds spending level for the first 5 years, drifts down ~1%/yr for the next 20, then holds (a ~18% real fall in mid-retirement — gentler than a straight-line drop). Flat is the pessimistic default. Late-life care costs are not auto-added.
Budget — your spending plan
Enter what you expect to spend, in today's money. We total it into your
essential (the floor that must always be covered) and comfortable
(your target) monthly take-home — then you can push that to your plan's target income.
Horizon
Sharing with a partner
— optional
Mark each line Me / Partner / Shared. Your plan only funds your share — costs your
partner covers (their shopping, their car) drop out of your target but still show in the household total.
