Cost to own breakdown
| Item | Amount |
|---|---|
| Equipment cash price | $75,000.00 |
| Upfront payment | $7,500.00 |
| Upfront fees | $500.00 |
| Scheduled lease payments | $87,000.00 |
| End-of-lease buyout | $7,500.00 |
| Total cost to own | $102,500.00 |
Payments are treated as due at the end of each monthly period.
Taxes, insurance, maintenance, interim rent, late charges, and tax effects are excluded unless entered as upfront fees.
How to use this calculator
- Enter the equipment cash price before financing.
- Add the upfront payment, lease payment, number of payments, buyout amount, and upfront fees.
- Choose whether recurring lease payments are due at the beginning or end of each month.
- Use the implied rate and total cost to compare the lease with paying cash or using a business loan.
How the lease rate is calculated
This calculator treats the lease quote as a set of cash flows required to own the equipment. The total cost to own is straightforward:
T = U + F + (M × N) + B
- P is the equipment cash price.
- U is the upfront payment.
- F is upfront fees paid at signing.
- M is the monthly lease payment.
- N is the number of monthly payments.
- B is the buyout, residual, balloon, or purchase-option amount.
The cost above cash price is T − P. That number is useful because it shows the dollars paid above the stated cash price if every scheduled payment is made and the buyout is exercised.
The implied monthly rate is the discount rate that makes the present value of the required lease cash flows equal the cash price. For payments due at the end of each month, the equation is:
P = U + F + M × [1 − (1 + r)^−N] ÷ r + B ÷ (1 + r)^N
For payments due at the beginning of each month, the monthly payment stream is multiplied by (1 + r) because each payment arrives one month earlier:
P = U + F + M × (1 + r) × [1 − (1 + r)^−N] ÷ r + B ÷ (1 + r)^N
When the monthly rate is zero, the formula uses the direct sum of the payments instead of dividing by zero. The annual rate shown is an effective annual rate: A = (1 + r)^12 − 1.
What moves the result
The buyout amount matters because it is part of the cost to own and a future cash flow in the rate calculation. Upfront payments and fees also matter, but they affect the rate differently from later payments because they are paid immediately. Payment timing can change the implied rate: a payment-in-advance lease gives the lender cash sooner, so the same dollar payment can imply a different rate.
What this leaves out
The calculator does not estimate taxes, insurance, maintenance, interim rent, late charges, documentation charges paid later, variable end-of-lease costs, depreciation, tax deductions, accounting classification, or the equipment's future market value. A fair-market-value purchase option cannot be evaluated until you estimate the buyout amount. The implied annual rate is a cash-flow comparison, not a legally defined APR disclosure.
Worked example
Suppose equipment has a $75,000 cash price. The lease requires $7,500 down, $500 in upfront fees, 60 monthly payments of $1,450 due at month end, and a $7,500 buyout to own the equipment.
Total recurring payments are $87,000. Total cost to own is $102,500, so the cost above the cash price is $27,500. The buyout-inclusive monthly cost is $1,708.33 over 60 months. Solving the lease cash flows gives an implied monthly rate of about 1.12% and an effective annual rate of about 14.26%.
Common questions
How do I calculate the interest rate hidden in an equipment lease?
List every required cash flow: the upfront payment, upfront fees, each lease payment, and the buyout if you plan to own the equipment. The implied rate is the monthly discount rate that makes those cash flows equal the cash price, then it is converted to an effective annual rate.
Should the lease buyout be included in total financing cost?
Include the buyout when the goal is to compare the cost to own the equipment. Excluding it can make a lease with a large residual look cheaper than it is. If you expect to return the equipment instead, the buyout is not part of that scenario.
What is the difference between a $1 buyout and a fair-market-value lease?
A $1 buyout lease has a known nominal purchase option, so the ownership cost can be estimated from the contract. A fair-market-value lease usually sets the purchase price later, so you need an estimated buyout before calculating cost to own.
Why is an implied lease rate different from a quoted factor rate?
A factor rate or lease factor is a quoting shortcut, not the same thing as an effective annual financing rate. The implied rate in this calculator comes from the timing and amount of actual cash flows, including upfront fees and the buyout.
Are documentation and origination fees included in the implied rate?
Yes, include fees paid at signing in the upfront fees field. Fees paid later are not modeled separately, so add them only if treating them as upfront is a reasonable approximation for your comparison.
What does payment in advance mean on an equipment lease?
Payment in advance means the recurring payment is due at the beginning of the month or period. Because the lender receives each payment sooner, choosing beginning-of-month timing changes the present value and can change the implied rate.
