Free Project Budget Planner

Plan one-off costs for events, trips, home projects, large purchases, and other fixed-scope spending.

Estimate each cost before you start, then record the actual amount as invoices, receipts, and bookings come in. The planner compares estimated and actual spending so you can see what remains and where the project is drifting over budget.

When to use a project budget

Use a project budget when the spending has a clear end point but too many moving parts to keep in your head. It is useful for weddings, holidays, renovations, moving house, car repairs, school costs, business purchases, and seasonal events.

Start with estimated costs, add a contingency line for unexpected expenses, and update actual costs as soon as they are confirmed. That gives you a current view of the project instead of a rough guess.

Planning tips

  • Break large costs into smaller line items so overspend is easier to spot.
  • Track deposits and final payments separately where timing matters.
  • Keep a contingency category visible until the project is finished.
