Collision Repair & Auto Body Paint Shop SBA 7(a) buy-vs-build cash-flow calculator
Stress-test building a collision repair & auto body paint shop from scratch against acquiring an existing cash-flowing resale using SBA 7(a) financing. Adjust startup CapEx, revenue, owner SDE margin, acquisition multiple, and loan terms to compare Year-1 ramp-up cash flow, Debt Service Coverage Ratio (DSCR), and 3-year cumulative owner take-home.
SBA 7(a) underwriting & payback takeaway:
At $2,450,000 revenue and 20% SDE margin ($490,000/yr pre-debt cash flow), buying an existing collision repair & auto body paint shop at 3.6× SDE ($1,764,000) generates $247,214/yr from Day 1 (2.02× DSCR), giving an immediate $316,031 Year-1 cash-flow advantage over building from scratch during a 14-month ramp-up. Once ramped in Year 2+, building from scratch ($500,000 CapEx) nets $421,183/yr (7.12× DSCR). By comparison, a 6% gross-sales franchise royalty on $2,450,000 revenue deducts $147,000/yr directly from owner cash flow.
