Sinking Fund Calculator
Enter a yearly or one-off bill and the months until it is due. You will see how much to set aside each month.
A sinking fund is money you put aside in small amounts for a cost you know is coming. The sum is simple: the bill amount divided by the number of months. Read more in our guide: Sinking Funds: Plan for Bills That Come Once a Year.
Worked example
Example with made-up numbers: a yearly bill of 600, due in 12 months.
600 ÷ 12 = 50.00 per month.
If the bill is due sooner, the monthly amount is higher. The same 600 due in 8 months is 75.00 a month. Bills can change in price, so check the amount when you can. See also: How to Start an Emergency Fund, Even a Small One.
