A sinking fund is money you set aside little by little to cover a known future expense, like a car replacement, a holiday, property taxes, or an annual insurance bill. This calculator tells you exactly how much to save each month to hit your target by a chosen deadline. Enter the total you need, the number of months until you need it, any amount you have already saved, and an optional interest rate if the money sits in a savings account earning a return. It uses the future value of an annuity formula so the interest is credited correctly, then solves for the required monthly deposit. Planning contributions this way turns a scary lump sum into a manageable habit and prevents the expense from ever becoming an emergency. Everything is calculated privately in your browser.
It is money you set aside regularly to reach a specific savings target by a deadline, spreading a future cost over time.
It divides your target across the months until the deadline, and if you add an interest rate, it accounts for growth to lower the deposit.
Yes. Leave interest at zero and it simply divides the goal by the number of months for a flat monthly deposit.
