What does paying a bill late really cost?

A $35 fee on a $120 bill you pay two weeks late is the same as borrowing that money at over 700% a year. This calculator shows the true cost — and helps you see which bill is cheaper to delay when you have to pick.

One bill

Which of two bills is cheaper to delay?

Sometimes you can pay one bill now and one later. If neither threatens a shutoff, eviction, repossession, coverage lapse, or court deadline, cost can decide.

Bill A
Bill B

What this calculator does and doesn't know

A planning tool, not financial or legal advice. Your billers' and your state's actual rules control.

Track the dates, not just the cost

The BillTriage app reads due dates, late-fee dates, and shutoff dates from a scan of the bill and ranks them for you. Private, on your phone, $2.99 once.
