Everything you need to know about lease accounting standards—in plain English.
ASC 842 is an accounting standard from FASB (Financial Accounting Standards Board) that changed how companies report leases on their financial statements.
The big change: Before ASC 842, many leases (called "operating leases") were invisible on the balance sheet. You'd just show the monthly rent as an expense. The actual obligation—all those future payments you owed—didn't appear anywhere.
ASC 842 changed that. Now, virtually all leases longer than 12 months must appear on your balance sheet as both an asset (your right to use the leased item) and a liability (your obligation to make payments).
Why does this matter? Your balance sheet now shows a more complete picture of your company's obligations. Investors, lenders, and other stakeholders can see the true extent of your lease commitments.
If you're a small business that only prepares tax returns and doesn't issue formal financial statements, you may not need full ASC 842 compliance. But if you have lenders, investors, or other stakeholders who expect GAAP financials, you need to follow these rules.
This represents your right to use the leased property or equipment over the lease term. Think of it as the value of having access to that asset. It goes on your balance sheet as an asset.
How it's calculated: Generally, the present value of all your future lease payments (plus any upfront costs you paid, minus any incentives you received from the landlord).
What happens to it: You amortize (gradually expense) the ROU asset over the lease term, similar to depreciating a piece of equipment.
This is your obligation to make future lease payments. It's a liability on your balance sheet because you owe money in the future.
How it's calculated: The present value of your remaining lease payments.
What happens to it: Each time you make a payment, part goes toward the liability (reducing what you owe) and part goes toward interest expense. It works similar to a loan.
Since you're promising to pay money in the future, we need to calculate what that future money is worth today. A dollar you'll pay 5 years from now is worth less than a dollar you pay today—that's the time value of money.
Discount rate: You need an interest rate to calculate present value. Ideally, use the rate implicit in the lease (if your landlord disclosed it). More commonly, you'll use your "incremental borrowing rate"—essentially, the rate you'd pay if you borrowed that amount of money from a bank for a similar term.
You sign a 3-year office lease for $3,000/month with a 6% discount rate.
Both types now go on the balance sheet, but they're accounted for slightly differently:
Operating Lease: You're essentially renting. Expense is recognized evenly over the lease term (straight-line). Most office and retail space leases fall here.
Finance Lease: You're essentially buying the asset over time. Expense is front-loaded (higher in early years, lower later). A lease is a finance lease if any of these are true:
To properly account for a lease under ASC 842, you'll need:
You'll show new line items: Right-of-Use Assets and Lease Liabilities. This increases both your total assets and total liabilities.
Because you're adding assets and liabilities, ratios change:
If you have loan covenants based on these ratios, check with your lender—they may need to be adjusted.
Each period, you'll need to record:
Good news: if a lease is 12 months or less (including any renewal options you're likely to exercise), you can elect to keep it off the balance sheet. Just expense the payments as you go, like the old rules.
This election is made by asset class, not lease-by-lease. So if you elect it for vehicles, it applies to all your short-term vehicle leases.
In addition to the balance sheet presentation, ASC 842 requires detailed footnote disclosures including:
