Plan the bills that don’t come every month

How to Budget for Irregular Expenses (Without the Annual Panic)
A simple, repeatable way to handle the bills that don't come monthly — insurance, property tax, registration, holidays — so the heavy months stop ambushing you.
Why we built this
Most people aren’t bad with money — they’re budgeting the wrong unit of time. A monthly budget looks fine right up until April, when a property-tax installment, an insurance renewal and a registration fee all land in the same four weeks. The bills were never secret; nobody had just added them up side by side. BillMapper does that one thing well: it lays a year of irregular bills on a calendar so the heavy months stop being a surprise.
How it works
- List your lumpy bills — amount, how often, which month. Your list saves in your browser, so you can come back and update it.
- See your year on a calendar, with the worst month flagged and the even monthly set-aside that pre-funds everything.
- Take it with you — print a one-page copy or export the due dates to your own calendar. Nothing you type is uploaded, ever.
