For car builders
Project car build budget calculator
List your parts, add labor and a cushion for surprises, and see what the build really costs, what's left to buy and when you'll finish.
Your build
Starts with a sample list. Edit, delete or add your own parts. Tick "Bought" for parts you already have.
How to budget a project car build
1. Write down every part before you buy any
The fastest way to blow a budget is buying parts as you see them. List the whole build first, with a real price for each part, so you know the finish line before you start.
2. Do it in the right order
Maintenance and safety first (fluids, belts, brakes, tires), then handling (suspension, alignment, seats), then power and looks. Parts from later stages often need the earlier ones done anyway.
3. Track labor separately
Even if you wrench yourself, some jobs need a shop: alignments, tire mounting, tuning, welding. Labor is easy to forget and can rival the cost of the parts.
4. Add a contingency
Broken bolts, extra fluids, hardware you didn't know you needed and parts that don't fit the first time add up. A 15–25% cushion keeps the build moving instead of stalling for a month.
5. Turn the total into a monthly number
Divide what's left by what you can set aside each month. A finish date makes it easier to say no to parts that aren't on the list.
