HVAC Loan Debt‑to‑Income (DTI) Calculator

If the projected monthly payment fits comfortably in your cash flow, you likely meet the DTI threshold – the next step is a soft‑pull rate check. The exact rate you qualify for still depends on your full credit profile and loan terms.

What changes your rate / answer

• Credit score – higher scores pull the APR toward the low‑end of the 8‑25% equipment‑financing range and can raise the DTI ceiling you’re allowed.
• Loan term – extending months spreads the payment but adds total interest, which nudges the DTI upward.
• Down payment or collateral – a cash‑down or securing the loan with the HVAC equipment (or a home equity line) reduces the financed amount and improves the ratio.
• Existing debt load – paying down other loans or credit‑card balances directly lowers the denominator of the DTI.
• Financing product – switching from standard equipment financing to a HELOC (Prime + 0.5‑3%) or a business line of credit (Prime + 3‑mid‑20s) changes the monthly cost used in the calculation.

How to use this

• Enter total monthly gross income – include contract revenue, rent, salary, or other recurring earnings.
• Add all recurring debt payments – existing loan installments, credit‑card minimums, lease payments, etc.
• Specify the HVAC loan amount, APR and term – defaults reflect a typical $25K equipment loan at 12% over 5 years.
• Read the DTI result – a percentage at or below 43% generally qualifies for our partner’s HELOC and most equipment‑financing offers.
• Adjust inputs – try a larger down payment, a longer term, or a lower APR to see how the DTI improves.

Bottom line

A DTI at or under 43% usually unlocks low‑interest HVAC financing; tweak the variables here to shape a loan that fits your budget.
