The Underwriting Decoder
Running the Numbers Like a Bank — discover the exact formulas underwriters use behind closed doors.
Inside the Underwriter's Brain
Banks don't make gut-feeling decisions. They run 5–7 standardized ratios and score your file against those benchmarks. Run these numbers before you apply, and you'll know your outcome before they do.
"Most applicants walk in blind. You're about to become the rare borrower who already knows their score — and who prepared accordingly."
The 5 Ratios That Determine Your Fate
Ratio 1: DSCR (Debt Service Coverage Ratio)
The single most important number in your file
This tells the bank: "For every $1 of debt payment, does this business generate $1.25 or more in cash?" If yes, you pass. If not, you need to either increase revenue, cut expenses, or reduce the loan amount.
Ratio: Current Ratio
Category: Liquidity
Measures your ability to pay short-term bills. Stays above 2.0 and lenders feel very comfortable.
Ratio: Debt-to-Equity Ratio
Category: Leverage
How much debt you carry vs. ownership equity. Below 3:1 is excellent. Above 5:1 raises serious concerns.
Ratio: Gross Profit Margin
Category: Profitability
Must exceed your industry average. If competitors margin at 40% and you're at 20%, the bank asks why.
Ratio: Trend Analysis
Category: Growth
Two years of revenue growth is powerful. A single down year needs an explanation letter. Two consecutive down years require a turnaround narrative.

"Knowing my DSCR was 2.46 before I walked in — instead of 1.25 — gave me actual negotiating power. I got a rate that was 0.5% lower because I presented like a professional."
