Modification Budget Planner

Plan a build without the spreadsheet. Add each mod with a cost and where it's up to — planned, ordered or installed — and watch the running total against your budget, what you've actually spent so far, and where the money goes. Your list is saved in this browser.

A planning estimate, not a quote — real prices vary by part, brand, supplier and whether you fit it yourself. Remember to leave headroom for consumables (fluids, fasteners, alignment), shipping and the jobs you discover halfway through.

About Modification Budget Planner

Plan a car build and keep the spend honest. Add each modification with a cost, a category (engine, suspension, wheels, brakes, exterior and more) and a status — planned, ordered or installed. The planner tracks the running total against your budget, shows how much you have actually spent versus still have to buy, and breaks the whole build down by category in an interactive donut. Your list is saved in your browser for next time.
