The formula
Spendable is the larger of zero and budget minus reserve. Divide it by the equal price and round down for whole purchases. The remainder stays after those purchases. The target comparison shows whether your chosen count fits.
Mechanic Legends Budget Calculator
Plan equal-priced purchases from a budget, price and reserve you enter. This tool supplies arithmetic rather than current car prices, workshop costs, auction odds or a prediction of job income.

Protect money for the next task
Enter an offer you can see in your current game. Keep the budget, cost and reserve in the same unit; Robux and in-game money are separate balances.

Equal-price purchases within your limit
Enter a non-negative budget and reserve and a cost greater than zero.
Your entered values are calculated in this browser. No Roblox account is needed.
Count is separate from value
A possible purchase count does not establish that a part fits, a car is useful or an auction yields the vehicle you want. Choose the project first, then use the arithmetic to keep its spending inside your own limit.
Recalculate different prices
The formula assumes each purchase costs the same amount. When a later offer changes price, calculate that offer separately. No game price, reward chance, earnings rate or special multiplier is prefilled.
Budget calculator questions
Does the calculator know current car or part prices?
No. Enter the price shown in your own live game. A blank default avoids presenting an old or unverified offer as current.
Does the result predict an auction reward?
No. It calculates an equal-priced purchase count. It does not know the auction pool, reward odds or the car inside the next mystery garage.
What happens when my reserve exceeds my budget?
The spendable amount becomes zero. The reserve is your chosen limit, not a game-imposed requirement.
