Auto Repair Shop Financial Model – Excel XLSX

BENEFITS OF THIS DOWNLOADABLE EXCEL DOCUMENT

1. Builds revenue bottom-up from bay capacity, staffed technicians, and billable-hours efficiency -- the real constraint.
2. Splits Labor Revenue and Parts Revenue into two real lines instead of one blended shop-revenue number.
3. Uses a real Master/Journeyman/Apprentice hiring timeline to determine staffed bays each month.

FINANCIAL MODELING EXCEL DESCRIPTION

Auto Repair Shop Financial Model is an Excel template (XLSX) available for immediate download upon purchase.

Most auto repair shop templates forecast revenue as a flat number per bay, or one blended "shop revenue" line. This model builds it the way a real shop actually earns money: a technician hiring timeline across Master, Journeyman, and Apprentice tiers determines how many bays are actually staffed each month, staffed bays multiplied by hours open and the standard 60%-75% billable-hours efficiency rate determines billable hours, and billable hours multiplied by the shop's labor rate becomes Labor Revenue – with Parts Revenue split out separately using a real parts-to-labor ratio, not blended into one number.

That bottom-up build is what makes the Debt Service Coverage Ratio meaningful: Year 1 DSCR clears the 1.25x SBA 7(a) minimum at 5.41x, backed by a full revenue-cushion stress test showing exactly how far billable-hours utilization could fall before the ratio breaks. Every wage and rate is sourced to 2026 data – BLS Automotive Service Technicians & Mechanics wage brackets for each staffing tier, national shop labor-rate and parts-to-labor benchmarks, and SBA 7(a) rates with the FY2026 tiered guarantee-fee schedule.

Change the bay count, shop labor rate, or hiring timeline on the Assumptions tab and it flows through Staffing & Payroll, Bay Capacity & Utilization, and Revenue Build into a full 3-statement model, DSCR & Lender Ratios, a 22-ratio Full Ratio Suite, a DuPont ROE Decomposition, and a Business Valuation & Exit tab with both a DCF (with and without terminal value) and a comparable-shop EV/EBITDA cross-check.

Twenty-four tabs cover Start Here, Disclaimer, Help & FAQ, Assumptions, Staffing & Payroll, Bay Capacity & Utilization, Revenue Build, Equipment & CapEx, Operating Expenses, Debt Schedule, the three financial statements, an Actual vs. Budget Tracker, Break-Even Analysis, DSCR & Lender Ratios, the Full Ratio Suite, DuPont ROE Decomposition, Scenario Analysis, Sensitivity Analysis (billable-hours utilization by labor rate), Business Valuation & Exit, an Executive Dashboard, Funding Requirement, and Settings.

Built as a native .xlsx with standard formulas only, verified across Excel, Google Sheets, LibreOffice, WPS, and ONLYOFFICE. A planning tool built from sourced 2026 data, not financial, legal, or tax advice.
