Truck Mortgage Calculator
Despite the name on the slug, this is not a property mortgage. A truck purchase is financed by a commercial vehicle loan, sometimes called a chattel loan, secured by the truck itself: there is no escrow account, no private mortgage insurance, and no property tax line in the math below. What this tool does is two jobs at once: it works out the monthly loan payment and total interest, then it checks whether the truck’s monthly revenue covers its operating costs plus that payment.
Estimate only. Confirm the APR in writing from the lender; dealer-quoted rates and fees can differ from the numbers used here. The cash-flow verdict bands are rules of thumb built into this tool, not lending criteria, and no lender approves or declines a loan on a $1,000-a-month line. This tool does not model taxes, depreciation, balloon or residual payments, or fees.
Quick Answer
A $79,500 tractor with $15,900 down (20%) and no trade-in finances $63,600. At 11.9% APR over 60 months the monthly payment is $1,411.54, total interest is $21,092.10, and the total cost is $100,592.10. With $12,000 monthly revenue and $5,800 operating costs, net before payment is $6,200, net after payment is $4,788.46 a month, the payment-to-income ratio is 11.76%, break-even revenue is $7,211.54 a month, and annual net is $57,461.58. At 8,500 miles a month the payment costs $0.166 per mile and operating costs run $0.682 per mile. Leave revenue blank and the tool still gives you the payment, without inventing a cash-flow verdict.

How to use the truck mortgage calculator
Enter the loan first, then decide whether you want the cash-flow half. Results stay hidden until you calculate.
- Enter price, down payment, and trade-in: the financed amount is price minus both. Down payment plus trade-in must stay below the price.
- Enter the APR and the term in months: use the lender’s APR in writing, not a dealer quote, and whole months. Typical terms run 36 to 84 months.
- For a payment only, leave monthly revenue blank and click Calculate: you get the payment, total interest, and total cost, plus per-mile lines if you entered miles. No revenue is invented for you.
- For the cash-flow check, enter revenue and operating costs: fuel, insurance, maintenance, and other, with miles if you want per-mile figures. The tool then shows net before and after payment, annual net, the payment-to-income ratio, break-even revenue, and a verdict.
- Copy or share with the buttons in the results box.
Invalid entries are rejected with a plain message: a missing or non-positive price or term, a negative down payment, trade-in, rate, expense, or miles figure, down payment plus trade-in at or above the price, and a revenue figure of 0 or below when revenue is entered. A blank revenue field is the one deliberate exception: it is a payment-only run, not an error. Blank expense and miles fields count as 0.
The monthly payment formula
The payment is the standard amortizing formula. P is the financed amount (price minus down payment minus trade-in), r is the monthly rate (APR divided by 12 and by 100), and n is the number of payments. With a 0% rate the payment is simply the financed amount divided by the term, which the tool handles as a special case rather than dividing by zero.
Financed amount = Price − down payment − trade-in
Total interest = Monthly payment × n − financed amount
Total cost of truck = Down payment + trade-in + (monthly payment × n)
Get the APR in writing from the lender, not the dealer’s stated rate. The same $65,000 financed over 60 months costs $1,349.29 a month and $15,957.59 in total interest at 9.0%, against $1,397.10 a month and $18,826.21 in total interest at 10.5%. The payment gap looks small, $47.81 a month, while the interest gap is $2,868.63. Compare offers on total interest, never on the monthly payment alone. For the same reason, check the mortgage payment calculator only for a property loan: its payment math is the same formula, but a house loan carries escrow, insurance, and tax treatment that this truck-loan tool deliberately leaves out.
Worked example, checked against this exact tool
The pre-filled figures are the worked example, and every number below is a real run of the calculator above.
| Line | Figure |
|---|---|
| Truck price / down / trade-in | $79,500 / $15,900 / $0 |
| Financed amount | $63,600.00 |
| Monthly payment, 11.9% over 60 months | $1,411.54 |
| Total interest / total of payments | $21,092.10 / $84,692.10 |
| Total cost of truck | $100,592.10 |
| Revenue / operating costs | $12,000 / $5,800 |
| Net before / after payment | $6,200.00 / $4,788.46 |
| Annual net / payment-to-income ratio | $57,461.58 / 11.76% |
| Break-even revenue | $7,211.54 a month |
| Payment / operating cost per mile, 8,500 miles | $0.166 / $0.682 |
A second check at 0% interest shows the special case working: $100,000 financed over 60 months at 0% is $1,666.67 a month with $0.00 total interest. And a payment-only run of the worked example, with revenue left blank, returns the same $1,411.54 payment and $21,092.10 total interest, with the cash-flow lines replaced by a note that revenue was not entered.
Can the truck pay for itself?
That is the cash-flow half, and it is where most payment-only tools stop short. Net after payment equals revenue minus operating expenses minus the truck payment. Break-even revenue equals operating expenses plus the payment: the monthly gross you must clear to stand still. In the example, anything under $7,211.54 a month loses money once the payment is counted, even if revenue still covers fuel and insurance on their own.
The verdict bands are the tool’s own rules of thumb, not lending criteria, and they read as follows: above $1,000 a month net after payment is labelled strong positive, above $0 is positive, above negative $500 is break-even, and anything worse is negative. A strong label here does not mean a lender will approve the loan, and a negative label does not mean one will decline it. Lenders weigh credit, reserves, equipment age, and the contract behind the revenue, none of which this tool sees. Treat the verdict as a first-pass sanity check, then run the numbers with your actual contract rates and a reserve for idle weeks, because idle weeks are what sink operators, not the note itself in a good month.
Two gaps in the inputs deserve stating plainly. Driver pay, tolls, permits, and plates have no fields of their own, so they must be folded into other monthly expenses or the net figure will flatter the truck. And the tool does not model taxes, depreciation, balloon or residual payments, or lender fees, so the total cost line is the loan cost, not the all-in cost of owning the truck. For running costs in detail, the dump truck operating cost calculator and the operating cost calculator help, and the trucking CPM calculator in this batch breaks costs down per mile in full.
Think in cost per mile
Trucking is priced per mile, so finance it per mile: payment per mile equals monthly payment divided by monthly miles, and operating cost per mile equals monthly operating expenses divided by monthly miles. In the example the payment is $0.166 a mile and operating costs are $0.682 a mile at 8,500 miles a month, for $0.848 a mile combined on the lines this tool models. That is well below the industry average total cost, because this tool’s expense lines exclude driver pay, benefits, tires, tolls, and permits.
For scale, the American Transportation Research Institute’s 2026 update puts the average total marginal cost at $2.336 per mile for 2025, with fuel at $0.482, truck and trailer payments at $0.404 combined, repair and maintenance at $0.215, and insurance at $0.106. Use that benchmark as a reality check on your own expense inputs: if your entered costs total far less than $2.336 a mile, something real is probably sitting in the other field, or missing from it entirely. The truck depreciation calculator covers the other side of the same decision, what the truck will be worth when the loan is paid off.
Down payment, term, and trade-in levers
A bigger down payment or trade-in cuts the financed amount directly. Every $10,000 less financed saves $221.94 a month at 11.9% over 60 months, which is the honest version of the old roughly $220 claim. Longer terms lower the payment but raise total interest sharply, and shorter terms do the reverse. Run the same $63,600 at 11.9% across terms before you sign:
| Term | Monthly payment | Total interest |
|---|---|---|
| 36 months | $2,109.39 | $12,338.17 |
| 60 months | $1,411.54 | $21,092.10 |
| 84 months | $1,119.32 | $30,422.50 |
Stretching from 60 to 84 months saves $292.22 a month but adds $9,330.40 in interest, and it keeps you paying on a truck that is two years older, with maintenance climbing as the warranty and the easy years fall behind you. The cheapest payment is rarely the cheapest loan.
What competing calculators miss
Truck-loan tools fall into a few camps, and each leaves something on the table.
- Payment-only specialists (the Drivewyze pattern): price, down payment, trade-in, rate, and term in, monthly payment out. Correct as far as it goes, but it never asks whether the truck earns enough to make the payment, so a buyer can leave with an affordable-looking payment on an unaffordable truck.
- Tractor-trailer payment tools with residual options: a useful extra, because a balloon or residual changes the payment, but this tool deliberately does not model residuals, and a reader comparing the two should know that the payments are not like for like.
- Rate tables without a tool (lender payment tables): a $100,000 truck across terms and rates is genuinely handy for a quick sense check, but a table cannot run your revenue against your costs, and it cannot show break-even revenue for your truck.
- Loan-plus-tax tools: payment plus a first-year tax shield from Section 179 is a real consideration for a buyer, but a tax shield is not cash flow in the month the payment is due, and mixing the two can make a tight loan look comfortable.
- The gap this page fills: payment and total interest together with revenue, operating costs, net before and after payment, break-even revenue, the payment-to-income ratio, and per-mile figures, plus a payment-only path for a reader who only wants the payment and refuses to invent revenue to get it.
Frequently asked questions
No. The name is kept because that is what people search for, but a truck purchase is financed by a commercial vehicle loan, sometimes called a chattel loan, secured by the truck itself. There is no escrow account, no private mortgage insurance, and no property tax in this calculation, and nothing here should be read as a property-mortgage quote.
With the amortizing formula M = P × r(1+r)^n ÷ ((1+r)^n − 1), where P is the financed amount, r is the monthly rate, and n is the number of payments. For $63,600 financed at 11.9% over 60 months, that gives $1,411.54 a month.
10 to 20% is typical; some lenders advertise 0% for strong credit. More down means less financed and less total interest. Every $10,000 less financed saves $221.94 a month at 11.9% over 60 months.
Yes. Leave monthly revenue blank and click Calculate. You get the payment, total interest, and total cost, plus per-mile lines if you entered miles. The cash-flow lines are replaced by a note, because the tool will not invent revenue to produce a verdict.
Compare monthly revenue to break-even revenue, which is operating expenses plus the payment. In the worked example, revenue must clear $7,211.54 a month to stand still after costs and the payment.
The monthly gross revenue at which the truck exactly covers its operating costs and loan payment, leaving net income of zero. Above it, the truck keeps money after the payment; below it, the truck loses money that month.
Monthly payment divided by monthly miles. In the worked example, $1,411.54 at 8,500 miles a month is $0.166 per mile for the payment alone, with operating costs adding $0.682 per mile on the lines this tool models.
Total interest. At 9.0% against 10.5% on $65,000 over 60 months, the payment gap is only $47.81 a month, while the interest gap is $2,868.63. A low payment on a long term can be the most expensive loan on the page.
Usually 3 to 7 years, or 36 to 84 months. Longer terms cut the payment but raise total interest: on $63,600 at 11.9%, 36 months costs $12,338.17 in interest, 60 months costs $21,092.10, and 84 months costs $30,422.50.
Some commercial lenders advertise 0% down and work with challenged credit, but rates run higher. Price the total interest before committing, and check whether the lender requires a personal guarantee or a larger reserve, since neither is modelled here.
