Understanding the Amortization Schedule for Lessees under ASC 842
This article provides a detailed breakdown of the Amortization Schedule setup for FASB lessee leases
The article is separated into key sections to help break down the calculations.
Date & Month
The first two columns will show the period for which the lease activity is recorded by Date in (YYYY-MM) format, and the Month count.

Amortization/Operating Lease Expense & ROU Asset

P&L Amortization Expense -Finance/ Operating Lease Expense- Operating (Column C):
Under ASC 842, operating lease expenses are recognized on a straight-line basis, while finance leases amortize the ROU Asset.
- Operating Lease: Calculated by dividing the Total Lease Payments by the lease term.
- Finance Lease: Determined as the ROU Asset Beginning Balance divided by the ROU Asset Life.
In the final month, the remaining amount ensures the ROU Asset value is reduced to $0.
ROU Asset Beginning (Column D):
Includes:
- Initial measurement of the Lease Liability (PV of future payments)
- Base lease payments made on or before the 15th of the lease start month
- Any Initial Direct Costs (if any)

ROU Asset (Column E):
The reduction in the ROU asset.
- Operating: Operating Lease Expense principal portion
- Finance: Amortization Expense principal portion
ROU Asset EOM (Column F):
Total of the ROU Asset at the end of the month, incorporating Amortization.

- Payments from the 1st-15th of the month are excluded from PV calculations for base leases but included in ROU Asset. For more information, see our FAQ article: Why is the first payment missing from the Lease Liability?
- Transition leases include all payments in liability calculations but exclude pre-start date payments. For more information, visit What is a Transition Lease?
