Startup Loan Readiness Calculator
Check your Debt Service Coverage Ratio against real SBA and conventional lender thresholds.
What this calculator does
Calculates your Debt Service Coverage Ratio (DSCR) — the single most important number in a small business loan decision — and checks it, along with credit score and time in business, against real SBA and conventional lender thresholds.
Who this is for
Small business owners and startup founders preparing to apply for an SBA or conventional business loan, wanting to gauge their approval odds before formally applying.
Methodology
DSCR (Debt Service Coverage Ratio) = Net Operating Income ÷ Total Annual Debt Service. This is the single most important number a lender calculates: it shows how many times over your business's cash flow could cover the proposed loan payment. Alongside DSCR, lenders assess personal credit score and time in business as the other core pillars of a startup/small-business loan decision.
Worked example
$120,000 annual net operating income, $80,000 proposed annual loan payment, 680 credit score, 18 months in business: DSCR = 120,000 ÷ 80,000 = 1.5x — comfortably above the 1.15-1.25x range most SBA lenders require. The 680 credit score also clears the 650+ threshold most SBA 7(a) lenders look for. However, at 18 months in business, this applicant falls short of the 2-year (24-month) history conventional lenders typically prefer — meaning despite a strong DSCR and credit score, an SBA microloan or alternative lender may be a more realistic near-term path than a standard SBA 7(a) loan.
Interpretation
A DSCR below 1.0 means the business's income doesn't fully cover the proposed debt payment — a near-automatic decline at most lenders. Most SBA lenders want at least 1.15x-1.25x as a safety margin against income volatility; conventional bank lenders often set the bar at 1.25x or higher. A credit score of 650+ generally opens the door to standard SBA 7(a) terms, while scores below 600 typically mean turning to SBA microloans or alternative lenders. Lenders also want to see at least 2 years of operating history for conventional loans — younger businesses usually need a microloan program or alternative financing instead.
How you compare to lender thresholds
Common mistakes
- Using gross revenue instead of net operating income. DSCR is based on income after operating expenses, not top-line revenue — using revenue dramatically overstates the ratio.
- Forgetting existing debt payments. Total debt service should include all business debt obligations, not just the new loan being requested.
- Assuming a strong DSCR alone guarantees approval. Credit score, time in business, collateral, and industry risk all factor in alongside DSCR — a strong ratio helps but doesn't override every other factor.
- Applying to conventional lenders before checking SBA microloan eligibility. Businesses under 2 years old with otherwise strong numbers often have better approval odds through SBA microloan programs than standard conventional channels.

Frequently Asked Questions
Can strong DSCR and credit score overcome a short business history?
Not always with conventional lenders, who typically want 2+ years of operating history regardless of how strong the other numbers look. Businesses under that threshold with strong DSCR and credit often have better odds through SBA microloan programs specifically designed for newer businesses.
What DSCR do lenders typically require?
Most SBA lenders require a minimum DSCR of 1.15x to 1.25x. Conventional bank lenders often want 1.25x or higher, and some require up to 1.5x for higher-risk industries.
What credit score do I need for a startup loan?
SBA 7(a) loans generally look for 650+ for the best terms, though some lenders and SBA microloans work with scores in the low 600s.
Can a true startup (under 2 years old) get an SBA loan?
Yes, but it's harder. Most conventional SBA 7(a) lenders prefer 2+ years of history. Newer businesses often turn to SBA microloans or alternative lenders.
