Direct answer
A sinking fund divides a known future expense into smaller regular contributions. It is for expected costs, while an emergency fund is for urgent and unexpected events.
At a glance
- Name the exact future purpose.
- Set a target and due date.
- Keep each fund’s balance visible.
Step-by-step method
- List predictable non-monthly costs. Examples include car repairs, annual insurance, school fees, Eid, travel, home maintenance, and device replacement.
- Estimate amount and timing. Use recent invoices and add a reasonable buffer.
- Calculate the contribution. Subtract current savings from the target and divide by the months remaining.
- Store the money separately. Use separate accounts, envelopes, or clearly tracked balances.
- Spend only for the named purpose. Update the next target after the expense occurs.
Practical example
A PKR 120,000 annual insurance payment due in twelve months requires PKR 10,000 per month. Starting six months before the due date would require PKR 20,000 per month.
Put this into practice
Treat the method as a draft that improves with evidence. Compare planned amounts with actual records at least weekly, explain large differences, and adjust future limits without hiding essential costs. A workable budget should be clear enough to follow and flexible enough to reflect a real household month.
