Sinking Funds: 12 Spending Pots Every UK Household Should Use (with Free Splitter)

Short version: give every £ a “job.” Put the big, irregular costs into named pots and fund them monthly so they stop blowing up your budget.

Rule of thumb to set each target

Monthly target = (Annual cost ÷ months left) + 10% buffer
Fund it automatically the day after payday using your Payday Flow (Bills → BufferPots → Fun).

1) Emergency Fund (starter buffer)

  • What it covers: 1–3 months of essentials (rent/mortgage, utilities, food, transport, minimum debt payments).
  • Target: starter £500–£1,000, then build toward 1–3 months.
  • Why: stops you reaching for credit when life happens (car repair, boiler fault, missed shifts).

Example: £1,200 target over 12 months → £100/mo.


2) Car Costs

  • What it covers: MOT, servicing, tyres, repairs, road tax; (optionally) insurance excess.
  • Target: Add your typical annual spend (MOT + service + tyres) + a small repair buffer.
  • Example: £500 MOT+service + £300 tyres + £200 buffer = £1,000 → £1,000 ÷ 12 = £84/mo.

3) Home Maintenance

  • What it covers: Boiler service, small repairs, DIY tools/materials, white goods breakdowns.
  • Target: 1–2% of property value per year (owners), or flat £50–£100/mo in a rental.
  • Example: £60/mo as a starting point.

4) Annual Bills & Insurance

  • What it covers: TV licence, contents/home insurance, car insurance (if you don’t keep it in “Car”), breakdown cover, Amazon/Costco, software subs paid annually.
  • Target: Sum your annual premiums + add 10% buffer.
  • Pro tip: Shop insurance 3–4 weeks before renewal.

5) Gifts & Christmas

  • What it covers: Birthdays, wedding gifts, Christmas (food + presents), Mother’s/Father’s Day.
  • Target: Decide total yearly gifting, divide by 12, add 10%.
  • Example: £720/yr → £60/mo; 10% buffer = £66/mo.

6) Travel / Holidays

  • What it covers: Flights, trains/fuel, hotels, spending money, passports, travel insurance.
  • Target: Pick the next trip budget, divide by months to go, add 10%.
  • Example: £1,200 summer trip in 8 months → £1,200 ÷ 8 = £150 + buffer ≈ £165/mo.

7) Kids / School

  • What it covers: Uniform, shoes, clubs, trips, birthdays, school photos, summer camps.
  • Target: Look back at last year; set a clear annual number + 10%.
  • Example: £600/yr → £55/mo with buffer.

8) Health / Dental / Glasses

  • What it covers: Prescriptions, dentist/hygienist, glasses/contacts, physio, small private fees.
  • Target: One check-up + hygienist + expected prescriptions + 10%.
  • Example: £360/yr → £33/mo.

9) Pets

  • What it covers: Insurance premiums/excess, vaccinations, flea/worming, food, boarding.
  • Target: Add insurance (or set a self-insure pot), routine care + 10%.
  • Example: £720/yr → £66/mo.

10) Tech & Appliances

  • What it covers: Phone, laptop, tablets, headphones, washing machine, fridge repairs/replacements.
  • Target: Plan for one major replacement every 3–5 years + small repairs.
  • Example: £600 phone every 3 years → £17/mo + £10/mo buffer = £27/mo.

11) Clothing & Shoes

  • What it covers: Seasonals, workwear, school shoes, coats, trainers.
  • Target: Set a realistic annual cap; divide by 12.
  • Example: £480/yr → £40/mo.

12) Fun & Experiences

  • What it covers: Meals out, gigs, mini-breaks, kids’ treats—guilt-free spending.
  • Target: Whatever you can afford after the essentials and other pots are funded.
  • Pro tip: Funding Fun last (after Bills → Buffer → Pots) keeps life balanced and sustainable.

FAQs

Q: I can’t afford all 12. Where do I start?
A: Emergency Fund, Car (if you drive), Annual Bills, and Gifts/Christmas. Add the rest as your budget loosens.

Q: Should debt come before sinking funds?
A: Minimum payments + a small starter Emergency Fund first. Then keep modest pots for predictable costs so you don’t put them back on credit. Throw the rest at your highest-priority debt.

Q: Can I use one big “Annual Costs” pot?
A: Yes—one pot is better than none. Named pots simply give more clarity.
