The spreadsheet works. Until it doesn’t.
Most people plan their big expenses in a spreadsheet, and honestly, it can do the job. But the sheet only knows what you last typed into it: timelines go stale, the inflation formula lives in your head, and nothing reminds you the furnace is due. Budget Forecast is the same arithmetic, kept current for you, on every device.

The same job, without the maintenance
Nothing here is magic. It’s the arithmetic you’d build in a sheet, already built, and kept current so you never open it to a stale plan.
The control you built the sheet for, kept
The reason you built a spreadsheet is that you wanted to see the math and own every number. That stays true here: nothing is a black box, and anything you disagree with, you can type over.
- ✓Every item shows its cost, timeline, and share of the monthly number
- ✓Override any price, quantity, or date, just like editing a cell
- ✓Export the whole plan to CSV or JSON anytime. No lock-in.

When a spreadsheet is still the right tool
We’re not here to tell you spreadsheets are bad. For some jobs they’re unbeatable, and pretending otherwise would be the first dishonest thing on this page.
Math you invent yourself
Modelling investment returns, comparing mortgage scenarios, or building a forecast nobody has built before. When the formula is the point, a spreadsheet is the right canvas.
One-off quick math
Splitting a bill, comparing two quotes, a calculation you’ll never open again. Opening a planner for that is overkill. So is opening a spreadsheet, honestly, but it’s closer.
Tracking every transaction
Budget Forecast deliberately doesn’t track your coffees. It plans the big, datable expenses. If you want transaction-level budgeting, pair it with a tracker; they answer different questions.
Switching from a spreadsheet
The three things people ask before they retire the sheet.
