35 sinking fund categories people always forget

The point of a sinking fund

A sinking fund turns a scary annual bill into a boring monthly transfer. Divide the cost by the months until it is due, and set that aside.

Car and transport

Service, MOT or inspection, tyres, insurance, road tax, breakdown cover, parking permits, unexpected repairs.

Home

Insurance, boiler service, appliance replacement, decorating, garden, tools, service charges, moving costs.

Health and wellbeing

Dentist, optician and glasses, prescriptions, physio, therapy, gym annual renewal.

Family, gifts and events

Christmas, birthdays, weddings, school trips, uniforms, childcare gaps in holidays.

Pets

Vaccinations, insurance, food in bulk, boarding, emergency vet.

Admin and professional

Passport and visas, driving licence, memberships, software renewals, accountant, courses and certifications.

Life and leisure

Holidays, flights, festivals, hobby equipment, tech replacement.

How much per month

For each item: annual cost / 12. Add them up — the total is the number most budgets are missing, and it explains why "unexpected" costs happen every single month. The sinking fund calculator does the totals for you.

Start with the next 90 days

Do not try to fund all 35 at once. Fund what is due in the next three months, then widen the net each month as cash frees up.

Keep them separate and named

Named pots get protected. A single "savings" balance gets raided. MoneyQuilt tracks each fund, its target and its due date, and tells you if a fund is behind.
