Sinking funds: how to save for trips, birthdays and big bills
Most "surprise" expenses aren't surprises at all: birthdays, festivals, insurance renewals and holidays come round on dates you already know. A sinking fund turns them into small monthly amounts.
What a sinking fund is
A sinking fund is money you set aside a little at a time for a specific cost on a known future date. Unlike an emergency fund, which is for the unexpected, a sinking fund is for things you can see coming.
How to set one up
- List upcoming costs with dates: a trip in four months, a family birthday, a yearly insurance premium, festival spending, a car service.
- Estimate each amount.
- Divide by the months left. A ₹24,000 trip in four months needs ₹6,000 a month.
- Set the money aside each payday, in a separate account or clearly earmarked.
Common things to save for
- Trips and holidays
- Birthdays, anniversaries and festival gifts
- Annual subscriptions, memberships and card fees
- Insurance premiums and taxes
- Planned repairs, a new phone or laptop
Keep the dates in view
The hardest part is remembering what's coming. Keep one list of dated events with a countdown to each, and review it when you plan your monthly budget. Seeing "Goa trip in 120 days" makes it obvious how much to put aside this month.
Why it works
Spreading costs evens out your months, so a big bill doesn't wreck your budget or end up on a credit card. It also makes spending on planned treats guilt-free, because the money was set aside for exactly that.
