How to budget for bills that arrive once a year

An annual bill for $600 looks like a $50-a-month expense when divided across a whole year. If the next payment is only four months away, the amount you need to find before the due date is different. A simple calendar catches the difference between the long-run cost and the money needed for the next payment.

Work back from the next due date

Write down the expected bill, the amount already set aside and the dates when you can add money. In a fictional example, the bill is $600 and you already have $120 ready. The gap is $480. If you have four monthly saving dates before the payment, putting away $120 on each date would cover it. Once the bill is paid, a full 12-month cycle at the same price calls for $50 a month.

If you get paid twice a month, use the actual pay dates. For example, eight deposits before the due date would require $60 each for the same $480 gap. Seven deposits would require a little under $69 each. Count the dates when the money will be available, including any transfer or payment lead time.

Put it beside the regular bills

The U.S. Consumer Financial Protection Bureau’s cash-flow worksheet starts with an opening balance, adds income and subtracts payments as they happen. That approach shows whether several expenses cluster before the next paycheck. Put the $600 due date beside rent and other regular commitments rather than leaving it as a monthly average.

Use the same worksheet for less predictable amounts. If last year’s bill was $600 and a new statement shows $660, a full-year target rises from $50 to $55 per month. Update the amount as soon as a confirmed figure arrives. If you use a rough estimate while waiting, label it and keep the expected date visible.

Make the calendar useful next year

• Record the bill amount and its next due date.
• Subtract what is already set aside and divide the gap by the remaining saving dates.
• Check the cash balance in the week of the payment.
• After paying, record the next expected date and start a fresh cycle.

A monthly average helps you see the recurring cost. The calendar helps you decide which paychecks need to cover it.
