What is a sinking fund?
A sinking fund is money you set aside a little at a time for a known future cost. Unlike an emergency fund, which covers the unexpected, a sinking fund covers things you can see coming even if you don’t know the exact date.
List the costs that don’t come monthly
- Insurance renewals: health, vehicle, home.
- Festivals, weddings and gifts.
- School or college fees and supplies.
- Annual subscriptions, memberships and taxes.
- Car or bike servicing, repairs and replacing a phone or laptop.
- Travel and trips home.
Work out the monthly amount
Divide the expected cost by the number of months until it’s due. If your health insurance renewal is ₹24,000 in twelve months, set aside ₹2,000 a month. If a ₹15,000 festival budget is five months away, set aside ₹3,000 a month. Add up all your sinking funds to see what they need from each salary.
Let the envelope carry over
A sinking fund only works if unspent money stays put. Turn on rollover for these envelopes so this month’s leftover carries into next month and the balance grows until the bill arrives. Then pay the bill from that envelope, and it’s covered without touching groceries or rent.
Keep them out of everyday spending
Money in a sinking fund isn’t spare. In Panda Budget, savings envelopes are kept out of your Safe to Spend number, so your everyday figure stays honest while the fund grows in the background.
