A sinking fund is money set aside every month for a large expense you can see coming. It stops yearly bills from landing on your credit card or eating into your emergency fund.

How to set one up#

  1. List the yearly or irregular expenses you expect in the next 12 months.
  2. Divide each amount by the number of months until it is due.
  3. Transfer the total of those monthly amounts to a separate account or recurring deposit on salary day.
  4. Pay the bill from that account when it arrives.
Example: three expenses due in 12 months
ExpenseAmountPer month
Health insurance renewal₹24,000₹2,000
School fees (second term)₹36,000₹3,000
Festival spending₹18,000₹1,500
Total₹78,000₹6,500

Keep sinking funds separate from your emergency fund, so you can see what each one is for.
