Frequently Asked Questions

What is the difference between Fixed Rate and Fixed Pay modes?

Fixed Pay Mode: Use this when you know the monthly payment and want to calculate the effective interest rate.

What is residual value in a lease?

Residual value is the estimated value of the asset at the end of the lease period. This value is used to calculate the depreciable base of the lease.

Formula:

Depreciable Base = Asset Value − Residual Value
How is the monthly payment calculated?

The monthly lease payment is calculated using the following formula:

M = [PV × r(1+r)^n] / [(1+r)^n - 1] + RV × r

Where:

  • M = Monthly Payment
  • PV = Present Value (Asset Value − Residual Value)
  • r = Monthly Interest Rate (Annual Rate / 12 / 100)
  • n = Total Number of Months
  • RV = Residual Value
What does the Principal vs Interest chart show?

The donut chart displays the proportion of your total lease payments allocated to:

  • Principal (Blue): The depreciation of the asset value
  • Interest (Green): The cost of financing (interest charges)
Can I use this calculator for auto leases?

Yes, this calculator works for any type of lease. However, for U.S. auto leases specifically, you may want to use the specialized Auto Lease Calculator which accounts for additional factors like acquisition fees, disposition fees, and sales tax.

What is the effective interest rate?

The effective interest rate is the actual annual percentage rate (APR) you're paying over the life of the lease. It takes into account the monthly payment, lease term, and asset values to determine the true cost of borrowing.
