Give the Extra Debt Payment Its Own Payday
An extra debt payment often begins as whatever is left at the end of the month. That sounds cautious. In practice, the money sits in checking beside groceries, fuel, birthday gifts, and three weeks of small decisions. By the time the month ends, there may be nothing left to send.
Give the payment a date. Treat it like a bill you chose, place it after income arrives, and leave enough room around it for the household to keep functioning. The exact amount can be modest. A payment that happens twelve times is more useful than an ambitious number that survives two months.
Start with a calendar. A payoff calculator can show how interest and time change under different payments. It cannot see that the electric bill, preschool tuition, and car insurance all leave during the same five days. The calendar can.
Write down each payday, each debt minimum, and every bill that must be paid before the next payday. Add a reasonable amount for groceries, transportation, medicine, and the other basics that happen between those dates. Use recent bank and card statements instead of memory. Memory tends to remember the mortgage and forget the $74 annual charge that arrives on Thursday.
