An Excel underwriting model for a business acquisition: recast the seller’s earnings, test your offer against the SBA 7(a) lender rules and find your walk-away price.

The model grades every add-back by the evidence behind it and applies each lender test: debt service coverage, the 10% equity injection, total debt against the valuation, and the valuation gap.

Inside the model

• Earnings Recast: three fiscal years and the trailing 12 months, with add-backs graded A, B or C
• Sources & Uses and Debt Schedule: the SBA loan, the guaranty fee, seller notes and your equity
• Price Grid: every price from 50% to 150% of asking, in 1% steps. The walk-away price is the highest that passes every test
• Sensitivity: coverage at nine prices as earnings fall or rise, and what a rise in Prime does to your payment
• Returns: cash-on-cash, IRR and the multiple on your cash
• Offer Memo: the deal on one page, for your lender

Two files: the blank model, and a worked example of a fictional HVAC business that shows every sheet in use. No macros and no circular references.

Includes The Deal Screen. One-time purchase.

Founding offer: code FOUNDING takes 20% off any paid tool until 30 November 2026, for the first 50 orders.
