What changes your rate and overall affordability

• Down Payment: A larger upfront capital investment lowers the principal amount, which reduces your monthly interest obligation and improves your loan-to-value ratio, often unlocking better tier pricing.
• Equipment Age: Financing a new vehicle often secures lower rates compared to used fleet inventory due to lower maintenance risks and longer warranty coverage periods, which lenders view as lower risk.
• Loan Term: Stretching the repayment period reduces the cash outlay per month, but usually results in a higher total interest cost over the life of the loan. Balance this against the vehicle's projected revenue lifespan.
• Business History: The length of time your business has been operational often serves as a proxy for risk; established fleets with multi-year filings typically see better terms than startups or owner-operators entering the market.

How to use this calculator

• Principal: Enter the total amount you intend to finance after subtracting your planned down payment. Ensure this figure includes relevant taxes and registration fees, not just the sticker price.
• Interest Rate: Input a realistic annual percentage rate based on current market averages for your credit tier. If you are unsure, run the calculation at 9% and again at 12% to see the payment swing.
• Term Length: Choose a repayment timeline that aligns with the projected revenue generated by the additional equipment to ensure it pays for itself.
