Full Maintenance Lease Calculator
A full maintenance lease bundles the vehicle payment with servicing, repairs, insurance and registration into one predictable monthly figure, which is why business fleets run on it: lumpy repair bills become a fixed cost you can budget. This calculator prices that bundle openly. Enter the vehicle price, term, APR and residual, then the maintenance package figures, and it returns the monthly payment with and without the bundle side by side, the cost over the term, and the true cost per mile.
Money-factor math: monthly interest = (adjusted cap cost + residual) x (APR / 2400). Maintenance, insurance, and registration are bundled into the monthly total. Note that Total lease cost (term) counts the lease payments and the down payment only; the fleet total and the cost per mile are the figures that include the bundle. Both totals are explained in the article below.
Quick Answer
For a $60,000 work truck on a 36-month full maintenance lease with $5,000 down, 6% APR, a 55% residual, $150 a month of maintenance, $100 of insurance, $400 a year of registration and 7% tax, the total monthly payment is $1,172.62. The lease alone, taxed, is $889.29, so the bundle premium is $283.33 a month. The all-in cost over the term is $47,214.40, which works out to $1.3115 per mile at 12,000 miles a year.
Key takeaways
- The bundle premium is the whole decision. Here it is $283.33 a month, $10,200.00 over the term: if your own servicing, insurance and registration would cost less than that, the bundle is buying convenience, not savings.
- Two different totals appear in the results, and they are not a mistake: Total lease cost counts lease payments plus the down payment only, while the fleet total and cost per mile include the bundle. Budget from the all-in figure.
- Tax is charged on the base lease payment only. The maintenance, insurance and registration lines are added after tax, which is how most monthly-tax states treat them, but not all.
- The APR you enter is converted to a money factor (APR divided by 2400) inside the finance charge. A dealer quoting a money factor of 0.0025 is quoting 6% on the terms used here.

How to use the full maintenance lease calculator
Fill in the vehicle and term first, then the bundle, then calculate. Every figure in the results traces back to those eleven inputs, and the worked example below is pre-filled so you can check the arithmetic before changing anything.
- Vehicle and lease terms: price, down payment, term in months, APR, and the residual as a percentage of the vehicle price. Add expected annual mileage; it affects only the cost per mile, never the payment.
- Maintenance bundle: monthly maintenance and insurance, the annual registration fee, and your sales tax rate. Maintenance is quoted monthly by lessors; divide an annual service contract by 12 to enter it here.
- Fleet size: set this above 1 to price several identical vehicles at once. Only the fleet total line changes; every other figure stays per vehicle.
- Read the comparison rows first: Total monthly payment against “Same lease without maintenance bundle” is the bundle decision in two numbers, and the premium row between them is what the package has to beat.
Three inputs are genuinely required: vehicle price, lease term and APR. Everything else defaults to zero when left blank, so a bare-bones lease with no bundle and no tax still calculates. Nothing stops you entering a residual above 100% or a down payment larger than the price, and both produce negative depreciation and strange payments rather than an error. Treat output like that as a sign an input is wrong, not as a quote.
The lease formula: depreciation plus a money-factor finance charge
A lease payment pays for two things: the value the vehicle loses while you use it, and a finance charge on the capital tied up in it. The full maintenance version then bolts the running-cost bundle onto that base payment.
Monthly depreciation = (Adjusted cap cost − Residual $) ÷ Lease term
Monthly interest = (Adjusted cap cost + Residual $) × (APR ÷ 2400)
Total monthly = Base monthly + Tax on base + Maintenance + Insurance + (Registration ÷ 12)
The finance charge formula surprises people the first time: the cap cost and the residual are added, not netted. You are renting money on the whole value in the vehicle, and the lessor’s capital is exposed to the full amount until the residual is realized at the end. Dividing APR by 2400 to get the money factor is the industry-standard conversion, the same one behind the payment progression that Regulation M requires lessors to disclose for consumer leases: gross and adjusted capitalized cost, residual value, depreciation and rent charge as separate line items. One caution from the Federal Reserve’s Regulation M summary is worth repeating: a lease rate is not an APR, and lessors are not permitted to call it one, because the components vary. This tool takes the rate in APR form purely so you can type a number you recognize; the math underneath is money-factor math.
For a business reader there is a tax layer the calculator deliberately leaves out. Under the IRS rules in Publication 463, the business-use share of lease payments on a vehicle used for work is generally deductible, and leases of higher-value cars attract an “inclusion amount” that trims the deduction. Fleets running five or more cars at the same time also cannot use the standard mileage rate and must track actual expenses, which is one reason a bundled, fixed monthly figure is administratively attractive in the first place. None of that changes the payment; it changes what the payment costs you after tax, and it belongs in a conversation with your accountant rather than in this tool.
Worked example: a $60,000 work truck over 36 months
The pre-filled example is a $60,000 truck: $5,000 down, 36 months, 6% APR, 55% residual, 12,000 miles a year, and a bundle of $150 maintenance, $100 insurance and $400 a year registration, with 7% sales tax. The adjusted cap cost is $55,000 and the residual is $33,000.
| Check run | Monthly total | Cost per mile | What it shows |
|---|---|---|---|
| Worked example, fleet of 1 | $1172.62 | $1.3115 | All-in term cost $47214.40 |
| Same lease, fleet of 5 | $1172.62 | $1.3115 | Fleet total $236072.00 over the term |
| Same lease, no bundle at all | $889.29 | $1.0282 | Premium $0.00; the bundle decision in one row |
| Same lease at 0% APR | $937.22 | $1.0761 | Total interest falls from $7920.00 to $0.00 |
One formatting note so the checks table and the results agree in your head: the tool prints money with a plain toFixed, so the fleet-of-5 total appears as $236072.00 rather than $236,072.00. The figures are identical; only the thousands separators are missing.
The two totals, the duplicate row, and other honest limits
Three quirks in the results are worth knowing before you quote from them, because each one has misled readers of lease calculators generally. None of them changes the monthly payment, which is the figure the tool exists to produce.
- “Total lease cost (term)” excludes the bundle. It is the taxed base payment times the term, plus the down payment: $37,014.40 on the worked example. The maintenance, insurance and registration totals listed right below it are not inside it. The genuinely all-in term figure, $47,214.40, appears only as the fleet total (at fleet size 1) and inside the cost per mile. If you are comparing a full maintenance quote against buying, compare $47,214.40, and for a mid-lease balance view the adjusted lease balance calculator covers the related payoff question.
- Two rows always match. “Base monthly lease (incl. tax)” and “Same lease without maintenance bundle” are the same number by construction, $889.29 on the example, because stripping the bundle off the total leaves exactly the taxed base. The second row is there as a comparison anchor, not as separate information; the premium row is the one carrying news.
- Tax and mileage have narrow jobs. Tax never touches the bundle lines, and annual mileage never touches the payment at all: it only spreads the all-in cost over miles. Exceeding a contractual mileage allowance is a separate charge the tool does not model; the excess mileage calculator prices that penalty directly.
What a full maintenance bundle buys, and when it loses
A real full maintenance (or fully maintained) lease typically folds scheduled servicing, covered repairs, and often tyres, roadside assistance and registration renewal into the single payment, with the lessor managing the work. This calculator prices the version of that idea you can put numbers on: the maintenance, insurance and registration lines you enter. Coverage breadth varies by lessor and is a contract question, not a calculation.
Where the bundle wins
- High-mileage commercial vehicles with expensive, predictable service intervals
- Fleets that value one invoice and managed downtime over squeezing each repair bill
- Budgeting certainty: the premium is fixed even when a gearbox is not
- Administration: no separate insurance, registration and servicing paperwork per vehicle
Where it usually loses
- Low-mileage vehicles that rarely need more than an annual service
- Operators with their own workshop, whose real maintenance cost sits well under the package price
- Terms where the premium exceeds your actual three-year repair history by a wide margin
- Contracts where exclusions leave the expensive failures outside the bundle anyway
The test is arithmetic, not instinct: total the premium over the term ($10,200.00 on the worked example) and set it against your own records for the same vehicle class. Fleets without records can approximate the maintenance side from the vehicle’s service schedule, and the ownership side of the comparison runs through the depreciation expense calculator if you are weighing a purchase instead. Property-style leases use a cousin of this structure, priced by the build to suit lease calculator, and a plain purchase loan for the same truck can be sanity-checked with the auto loan principal payment calculator.
What competing calculators miss
Lease calculators are plentiful; maintenance-bundled fleet lease calculators are not. The gaps break down by camp:
- Consumer lease calculators (TrueCar and its peers): careful money-factor walkthroughs with trade-ins and fees, aimed at one person leasing one car. No maintenance bundle, no insurance or registration lines, no fleet multiplier, no cost per mile. The exact questions a fleet buyer asks are the ones left out.
- Fully maintained lease providers (FleetPartners in Australia): the real product, servicing, tyres, roadside assistance and re-registration genuinely bundled, but the “calculator” is a vehicle shortlist that ends in an estimate and a sales conversation. No formula is published, no APR or residual can be entered, and the market is Australian novated and operating leases, not a U.S. fleet quote you can audit.
- Fleet cost calculators (Calculator City’s fleet tools): annual ownership economics across a fleet, fuel and maintenance included, but no lease structure at all: no cap cost, no residual, no money factor, so they cannot price the contract a lessor is actually offering.
- The gap this page fills: standard lease math with the bundle itemized on top, the with-and-without comparison in the same result set, a fleet multiplier, and a true cost per mile that uses the all-in total rather than the lease-only one. It also publishes its own limits, including the lease-only term total, instead of letting the label imply more than the number contains.
Frequently asked questions
It is a vehicle or equipment lease where scheduled maintenance and repairs are bundled into the monthly payment, often alongside insurance and registration. The lessor handles servicing, which is why fleets favor it: costs become fixed and downtime is managed.
Using money-factor math: add the adjusted capitalized cost to the residual value, then multiply by the money factor (APR divided by 2400). This is the same method dealers use, and it is why a higher residual lowers your payment.
Compare the bundle premium (shown in the results) against your actual repair history. For high-mileage commercial vehicles with expensive service intervals, the bundle often wins on predictability alone; for low-mileage passenger cars it frequently does not.
Total lease cost (term) counts only the taxed base lease payments plus the down payment, so $37014.40 on the worked example. The all-in figure, which adds total maintenance, insurance and registration, appears as the fleet total ($47214.40 at fleet size 1) and is the number inside the true cost per mile. Use the all-in figure when comparing the lease against buying.
Most leases charge 15 to 30 cents per excess mile at turn-in. The true cost per mile in the results helps you judge whether buying extra miles upfront is cheaper than paying penalties later.
Enter it as a monthly figure, since that is how lessors quote maintenance packages. Annual service contracts can simply be divided by 12.
Yes. The math is identical for construction or farm equipment on full-service leases; just enter the equipment price, residual, and the service package cost.
Sales tax is applied to the base monthly payment (depreciation plus interest), which matches how most US states tax leases. Some states tax the full price or the down payment differently, so confirm with your lessor.
