Line of Credit Affordability Calculator – 2026

If the monthly payment shown fits comfortably within 8–12% of your gross revenue, you’re in the sweet spot for most 2026 lenders — the next step is a soft‑pull rate check that won’t dent your score. The exact APR still hinges on your credit profile, collateral and how you structure the draw period.

What changes your rate / answer (best business lines of credit 2026)

• Credit score – FICO 740+ unlocks the lowest‑tier APR; fair‑credit (620‑679) adds roughly 3–5 percentage points.
• Term length – Shorter draw periods (12‑24 months) keep the rate nearer the 8‑10 % range, while extending to 36 months pushes total interest up 20‑30 %.
• Secured vs. unsecured – Pledging assets can shave 1‑3 percentage points off the APR.
• Usage pattern – Higher utilization (above 80 % of the limit) may trigger a higher rate tier.
• Collateral type – New equipment or inventory collateral is cheaper than used assets, which add 1‑2 % to the APR.

How to use this (how to get a line of credit)

1. Enter the desired credit limit (typical small‑business revolving credit runs $10 k–$250 k).
2. Select an estimated APR based on your credit band; the default of 12 % reflects a mid‑range unsecured line.
3. Pick a repayment horizon – most revolving lines require minimum monthly payments calculated over a 12‑ to 36‑month pay‑down period.
4. Review the monthly payment – compare it to the 8‑12 % of gross monthly revenue guideline.
5. Adjust any input (lower limit, shorter term, better rate) until the payment sits inside your cash‑flow comfort zone.

The result shows a concrete payment figure and the implied annual percentage rate. If the payment is too high, lower the limit or improve your credit score before applying.
