How to Calculate the Lessor Implicit Rate on a Lease

by John Cromwell; Updated September 26, 2017

An important accounting issue for lessors recording a lease is how much of the overall value should be recorded as gross investment and how much as unearned income. Vital to the calculation of these balances is the lessor’s implicit rate on the lease, as that percentage allows the lessor to divide the value of the lease. The nature of the implicit rate calculation is very complex and requires either repeated trial and error or the use of computer spreadsheet.

Step 1

Determine the fair market value of the underlying rented property. The fair market value is what the leased property would sell for if placed on the open market, and the seller was not under pressure to sell the property to obtain the necessary cash.

Step 2

Read the lease and determine the minimum lease payment and number of payments that will occur during the lease. The minimum lease payment is the amount the lessee is expected to pay monthly per the terms of the agreement. The lease may explicitly state how many payments the lessee is expected to make, or you may have to figure it out separately. For example, if the lease just says the lessee will rent the property for four years and pay monthly, the total number of payments will be 48.

Step 3

Determine the implicit rate using the "RATE" function in Microsoft Excel, a Google Docs Spreadsheet, or Apple iWorks Numbers. To calculate the implicit rate, find the percentage that, when applied to the sum of the minimum lease payments, causes the present value of all the payments to equal the current fair market price of the rental property. On a computer spreadsheet, type =RATE( in a cell. After the parenthesis, record a series of numbers. For the first set of digits, record the number of payments and then follow that with a comma. Record the value of each rental payment and follow that with a comma. Record the negative value of the fair market price of the rental property and enter a closed parenthesis. Hit enter and that will give you the implicit rate per payment period. So for example, assume a lease of 1 year, with monthly payment of $1,000, on a rental property of $10,000. The equation for that would be =RATE(12,500,-10000). The result is a monthly implicit rate of 3 percent.

Tips

  • If you are about to enter into a lease as either a lessor or lessee, consider consulting a licensed attorney in your area to ensure that your rights are protected. Also, considering using a certified public accountant to ensure that the implicit rate is correctly calculated. Information provided is for educational purposes only.
