See your real monthly payment, the total interest you will pay, and what a longer term really costs — before you sign anything.
How truck and trailer financing works
Buying a semi truck, hotshot rig, box truck or trailer is usually the biggest single purchase an owner-operator makes, and most buyers finance it rather than paying cash. A commercial truck loan works like other equipment loans: a lender pays the seller, you repay the lender in monthly installments over a fixed term, and the truck itself is the collateral. If payments stop, the lender can repossess the truck, which is why lenders look closely at your credit, your business history and the age of the equipment before they quote a rate. The calculator above gives you the payment, total interest and total cost for any combination of price, down payment, APR, term and balloon, so you can see the real cost before you talk to a lender.
Down payments: what lenders expect
Most lenders ask for a down payment of 10% to 20% of the purchase price when the buyer is an established carrier with a track record. New authorities, businesses that have just received their MC or DOT authority, are commonly asked for more, often 20% or more, because the business has no track record for the lender to judge. A larger down payment lowers the loan amount, the monthly payment and the total interest, and it can also improve the rate a lender is willing to offer.
What drives the APR
Three things matter most: your credit, the age of your authority and the age of the equipment. Strong credit and an established authority with steady revenue earn lower rates, while a new authority or a lower credit score usually means a higher APR, often in the 9% to 15% range. Older trucks cost more to finance too, because lenders charge more for equipment near the end of its useful life, and some will not finance trucks over a certain age at all. Because every lender weighs these factors a little differently, the cleanest way to compare offers is to line them up on the same loan amount, APR and term, which is exactly what this calculator does.
Shorter term or longer term?
The term comparison table above shows the same $65,000 loan, a $75,000 truck with $10,000 down at 9.5% APR, at 36, 48, 60 and 72 months. A longer term lowers the monthly payment, $2,082.14 a month at 36 months versus $1,187.85 at 72 months, but it adds thousands in total interest, $9,957.10 at 36 months compared with $20,525.55 at 72 months. The payment that fits your cash flow is the one you can afford every month, but a shorter term leaves far more money in your pocket over the life of the loan. Before you stretch a term to make the payment fit, check whether the truck still earns money at the higher monthly payment with the Per-Mile Profit Calculator and price the insurance side of the monthly cost with the Texas Trucking Insurance Cost Estimator.
How balloon loans work
A balloon loan keeps the monthly payments lower by leaving a large single payment, the balloon, due at the end of the loan. For example, a $20,000 balloon on this $65,000 loan cuts the 60-month payment from $1,365.12 to $1,103.42, but you still owe that $20,000 on the last day. The risk is what happens then: if the truck has lost value, or your credit has weakened, you may not be able to refinance the balloon or sell the truck for enough to cover it. A balloon loan can make sense when you expect to trade the truck in or sell it before the balloon comes due, but plan that exit in advance and never assume it will work out.
Results are estimates, not a lending offer. The numbers from this calculator are estimates only, not a lending offer, quote or credit approval. Your actual APR, terms and monthly payment depend on your credit, the lender, the equipment and the market at the time you apply. Treat the figures as a planning tool, then get quotes from two or three lenders and compare the same loan amount, APR and term side by side. You can browse more free tools on the Trucking Tools hub.
Frequently asked questions
How much is a $65,000 truck loan per month?
At 9.5% APR over 60 months, a $65,000 loan costs $1,365.12 a month, with $16,907.26 in total interest. Your payment changes with the down payment, APR and term, so try the calculator above with your own numbers.
Does a longer loan term save money?
No. A longer term lowers the monthly payment but costs more overall. On that same $65,000 loan at 9.5% APR, stretching from 60 to 72 months drops the payment from $1,365.12 to $1,187.85, but total interest rises from $16,907.26 to $20,525.55.
What is a balloon payment?
A balloon payment is a large single payment due at the end of the loan, which keeps the monthly payments lower until then. For example, a $20,000 balloon on a $65,000 loan at 9.5% APR over 60 months cuts the monthly payment from $1,365.12 to $1,103.42, but the $20,000 is still due on the final day.
How much down payment does a new authority need?
There is no fixed rule. Lenders commonly ask new authorities for a larger down payment, often 20% or more, because the business has no track record to judge. A bigger down payment also lowers your loan amount, monthly payment and total interest.
