Tip: turn your phone sideways for a bigger view.
The big idea
Fixed, Flex, and Lumpy.
- FixedYour bills, on a schedule, even once a year. Mortgage, phone, car insurance, property tax.
- FlexEveryday spending. Castworth learns it and predicts it. Groceries, gas, eating out.
- LumpyBig costs that don’t come on a regular schedule. Set-asides save for them ahead of time. A broken washer, a vacation.
