SBA 7(a) Stress-Test & DSCR Engine · v1.0

Updated 2026-05-09

Pressure-test the deal before the bank does.

Acquisitions fail when coverage is thin. Model DSCR at 1.20× and 1.25× hurdles, layer in revenue-drop and rate-shock scenarios, and surface the post-debt cash flow that survives a soft year.

2026 Underwriting Benchmarks

While SBA SOP 50 10 8 allows for a minimum 1.1:1 DSCR on smaller loans, most acquisition lenders in 2026 target a 1.25x to 1.35x baseline for larger transactions. Our sensitivity model accounts for operating leverage—where fixed overhead costs cause cash flow to fluctuate more than revenue.

§ 02 · Read

How to read your stress test.

READ 01

Healthy

1.35×+

Real buffer for rate moves and revenue dips. Lender will fund without restructuring asks.

READ 02

Workable

1.20–1.34×

Lender-preferred range with one structural lever — bigger seller note on standby, longer amortization, or 5% more equity.

READ 03

Reprice or pass

< 1.20×

Below SOP comfort. Always check the downside column — if base is thin, downside is structurally fragile.

READ 04

Post-debt fragile

< $25K

Buffer after debt service, owner pay, and capex. Below this and a soft year breaks the deal regardless of headline DSCR.
