Business Loan Calculator Guide: What to Calculate Before You Sign

The four numbers every borrower should run before signing — DSCR, total cost of capital, monthly burden, and cents-on-the-dollar.

Last reviewed: April 2026

TL;DR

Before signing any business loan, calculate four numbers: monthly debt service vs monthly revenue (target under 12–15%), debt service coverage ratio (target 1.25+), total cost of capital (total payback minus principal), and cents-on-the-dollar cost (cost divided by principal).

Disclosure: Rates, fees, government statistics, and program terms shown reflect publicly available data from the cited sources as of April 2026. This content is for educational purposes only and is not an offer of credit or financial advice. Verify current terms with the lender or program administrator before relying on them. Live data points are pulled from U.S. government APIs (Federal Reserve / FRED, BLS, U.S. Census Bureau, U.S. Treasury, SBA) and may be delayed.

1. Monthly debt service ratio

Monthly loan payment ÷ monthly revenue. Target under 12–15%. Above 20% means you're likely over-leveraged.

2. Debt service coverage ratio (DSCR)

Annual net operating income ÷ annual debt service. SBA wants 1.25+. Banks want 1.35+.

3. Total cost of capital

Total payback minus principal. A $100K loan with $130K payback has $30K total cost — regardless of how it's structured (factor or APR).

4. Cents-on-the-dollar (CoD)

Total cost ÷ principal. The single best apples-to-apples comparison across product types. $30K cost on $100K = 30 cents on the dollar.

Pros of running the math first

  • Avoids over-leverage that triggers default
  • Identifies the cheapest option across product types
  • Strengthens your negotiating position

Common mistakes

  • Comparing APR to factor rate without converting
  • Ignoring origination fees in cost calculations
  • Calculating DSCR off gross revenue instead of NOI
  • Missing the impact of daily debit on cash flow

MCA / Factor Rate Calculator

Convert a factor rate offer to total cost, daily remit, and approximate APR. Useful for comparing MCA offers against term loan APRs.

Methodology

Total payback = principal × factor. APR-equivalent ≈ (factor − 1) × (365 / term days). This is an approximation — true APR is slightly higher because daily remittances reduce balance over time. APR is defined per the federal Truth in Lending Act (12 CFR § 1026, Regulation Z). MCAs are typically structured as a purchase of receivables and not subject to TILA APR disclosure, but several states (CA SB 1235, NY S5470) require commercial financing disclosures with an APR-equivalent.

Business Term Loan Calculator

Standard amortization: fixed APR, fixed weekly payment. Same formula banks and SBA lenders use.

Methodology

Standard amortization formula: P × r / (1 − (1 + r)−n), where r is the monthly rate (APR / 12) and n is the term in months. APR is the annual percentage rate as defined in the federal Truth in Lending Act (12 CFR § 1026.22). Actual lender quotes may include origination fees that increase APR.

Compare Two Offers (APR-equivalent)

Paste any two offers — MCA, term loan, line of credit — and normalize them to the same yardstick.

Offer B

Lowest APR-equivalent wins on cost. Cents-on-the-dollar (CoD) shows total cost per dollar borrowed regardless of term length.
