Calculators for Auto Repair Shops
Three numbers most shops never actually calculate, and each one is worth real money. No login, no email, no gate on the answer. Every tool shows its formula and works through a real example, so you can check the math rather than trust it.
Effective Labor Rate Calculator
Your posted rate is not what you collect. Find the real number, and what the gap costs you in a year.
No-Show Cost Calculator
Put an annual figure on missed appointments, and see what cutting them would actually be worth before you spend anything on it.
Parts Markup Calculator
Price a part, see the margin it really produces, and check it against the range normal for that cost band. Markup is not margin.
Free invoice and estimate templates
Fill in the job, print it or save it as a PDF. Both run entirely in your browser, so nothing you type is uploaded.
Mechanic Invoice Generator
Labor, parts at your markup, a travel or service-call fee and sales tax on a clean invoice you can print or save as a PDF.
Auto Repair Estimate Template
An itemized estimate or quote with a valid-until date and a customer signature line for authorization before the work starts.
Why these three
Effective labor rate tells you what you actually collect per billed hour, which is almost never the rate on your wall. No-show cost turns missed appointments from an annoyance into a number you can compare against the cost of fixing it. Parts markup separates markup from margin, which are different numbers that get treated as the same one constantly.
