How to use the equipment-loan calculator

This calculator estimates your monthly payment on a fixed-term equipment loan for a chiller project. Use it when you've gotten a quote on a specific chiller and want to sanity-check whether the cash flow works before you commit. For commercial chiller projects in the $25,000 to $500,000 range, equipment loans typically run 60 to 84 months at single-digit to low-double-digit APR depending on credit profile, business age, and lender bench depth in commercial HVAC.

Enter the total project cost in the loan amount field — not just the chiller. The equipment is typically only 50-to-60% of the all-in cost; if you finance only the equipment line item, you'll be scrambling for working capital to cover removal, mechanical, electrical, and commissioning. Lenders who specialize in chiller deals will finance the whole project. Then enter the annualized interest rate from the lender's term sheet (use the all-in APR if quoted, not the headline rate), and the loan term in months.

The monthly payment that comes back is your minimum obligation each month for the full term. Plug it into your operating budget alongside the operating savings the new chiller delivers — a high-efficiency or magnetic-bearing unit typically reduces the cooling portion of your utility bill by 20-to-40% versus a 20-year-old baseline. If the operating savings exceed the financing payment, the project is cash-flow accretive from month one. If the savings are smaller than the payment, the project is still defensible (you're amortizing a 15-to-20-year asset over 60 to 84 months) but the cash-flow case is operating-budget-dependent rather than self-financing.

For emergency replacements, the calculator's monthly payment is less important than the question of whether ANY financing can be in place within 24 to 48 hours. Run the numbers, but don't optimize for rate at the cost of speed when downtime is the bigger expense.
