To calculate the exit cap rate on a commercial property, divide the projected net operating income for the year after the sale by the expected sale price, then multiply by 100. Written as a formula: Exit Cap Rate = (Year N+1 NOI ÷ Projected Sale Price) × 100. If forward NOI is $600,000 and the projected sale price is $10,000,000, the exit cap rate is 6.0%. The math is easy. Getting the two inputs right is the entire job, because a half-point shift in this single assumption can move a property’s projected value by millions.
Projecting the Terminal NOI
The numerator follows the N+1 rule. If you plan to hold the property for seven years, you project income for year eight. A ten-year hold means projecting year eleven. A buyer at the end of your hold cares about what the asset will earn for them going forward, not what it earned for you in the final year of ownership.
Build Gross Income First
Start with gross potential rental income: base rents plus any ancillary revenue like parking, storage, or antenna leases.1J.P. Morgan. Calculating Net Operating Income in Multifamily Real Estate Subtract projected vacancy and credit losses to arrive at effective gross income. Vacancy assumptions deserve more thought than they usually get. The national office vacancy rate sat at 11.8% in early 2025, while industrial and multifamily properties ran far lower. A blanket rate applied without checking the specific asset class and submarket will distort everything downstream.
Subtract Operating Expenses
From effective gross income, deduct all recurring operating expenses: property taxes, insurance, utilities, repairs, maintenance, management fees, and professional services.1J.P. Morgan. Calculating Net Operating Income in Multifamily Real Estate What remains is net operating income. Debt service is not part of NOI. NOI reflects the property’s earning power independent of how a particular owner financed the purchase.
Decide Where Reserves Go
Replacement reserves (money set aside for roofs, HVAC, and similar large items) sit in a persistent gray area. Investment analysts typically keep reserves below the NOI line, treating them as a cash flow adjustment. Appraisers frequently deduct reserves above the line, reducing NOI itself. Neither approach is wrong. Consistency is non-negotiable. If you deduct reserves from NOI, the cap rate you compare against must come from reserve-adjusted NOIs too. Mixing the two methodologies produces a terminal value that is quietly wrong in a way nobody catches until the deal underperforms.
Estimating the Sale Price
The denominator is what a willing buyer would pay at the end of your holding period. Two approaches dominate, and they are circular by nature. Most investors move between them until the assumptions feel internally consistent.
Comparable Sales

Then apply a projected appreciation rate over the hold period to reflect market growth and any value-add work. The result is a forward-looking estimate of gross proceeds before transaction costs.
Cap-Rate-Derived Price
More commonly, the sale price is calculated by rearranging the formula: Sale Price = Forward NOI ÷ Exit Cap Rate. You assume an exit cap rate, then back into the terminal value. The circularity is obvious. You need to assume a cap rate to find the sale price, but the sale price is also an input to the cap rate formula. You break the loop by anchoring the exit cap rate to observable market data and stress-testing it through sensitivity analysis.
Where the Cycle Will Be
The phase of the real estate cycle at your projected exit date shapes what cap rate assumption is defensible. In expansionary periods with moderate rate increases, cap rates can hold steady because investors expect growing income. In periods of economic stress, cap rates tend to spike even if interest rates drop, because investors demand a higher return to compensate for uncertainty.3JPMorgan Chase. The Role of Cap Rates in Real Estate Projecting a sale seven or ten years out means taking a view on the cycle, which is inherently speculative. That is the reason sensitivity analysis exists.
Worked Example
Suppose you acquire a 50,000-square-foot office building for $8,000,000 at a going-in cap rate of 6.5%, and you plan to hold it for seven years.
Step 1. Project Year 8 NOI. You estimate gross potential income at $1,150,000 in year eight based on projected rent growth. You assume a 10% vacancy rate, bringing effective gross income to $1,035,000. Operating expenses total $415,000. Year 8 NOI equals $1,035,000 minus $415,000, or $620,000.
Step 2. Estimate the sale price. Based on comparable sales and projected market conditions, you estimate the building will sell for $8,850,000.
Step 3. Calculate the exit cap rate. $620,000 ÷ $8,850,000 = 0.0700, or 7.0%.
That 7.0% exit cap rate sits 50 basis points above the 6.5% going-in rate, which reflects the added uncertainty of projecting conditions seven years out. If you assumed a $9,500,000 sale price instead, the exit cap rate drops to 6.5%. If the sale price falls to $8,000,000, the exit cap rate rises to 7.75%. Those swings show why this one assumption deserves more scrutiny than any other variable in the model.
Going-In Cap Rate vs. Exit Cap Rate
The going-in cap rate reflects current conditions at acquisition. The exit cap rate is a forecast of conditions years in the future. Because forecasts carry risk, institutional underwriters almost always assume the exit cap rate will be higher than the going-in rate. The standard convention adds 25 to 50 basis points for a shorter hold of three to five years, and 50 to 75 basis points for a longer hold of seven to ten years. That cushion accounts for the possibility of rising interest rates, physical aging of the asset, or a downturn coinciding with the sale.
A lower exit cap rate than the going-in rate implies the property will be worth more per dollar of income at sale than it was at purchase. That is an aggressive bet on cap rate compression. It happens, particularly with value-add strategies where a distressed asset gets stabilized. Underwriting to that assumption in a base case is a red flag most sophisticated lenders and equity partners will push back on.
Running a Sensitivity Analysis
No single exit cap rate assumption should drive an investment decision. Run the model across a range, typically spanning 100 to 200 basis points, and track how the IRR and equity multiple respond at each level. A two-variable sensitivity table with exit cap rate on one axis and rent growth on the other will show whether the deal works only under optimistic conditions or holds up in a downturn.
If a deal produces a 15% IRR at a 6.5% exit cap rate but drops below 8% at a 7.5% exit cap rate, the investment is highly sensitive to exit pricing. That does not automatically kill the deal. It does tell you the return is being manufactured by residual value rather than by cash flow during the hold. Cash-flow-driven returns are more durable because they do not depend on guessing what a buyer will pay a decade from now.
What Drives the Rate You Should Assume
Interest Rates
Rising interest rates increase the cost of capital, which pushes cap rates upward. When borrowing costs rise, buyers cannot pay as much for the same stream of income, so prices fall and cap rates expand. Falling rates tend to compress cap rates by making the same cash flows more affordable to finance.3JPMorgan Chase. The Role of Cap Rates in Real Estate The 10-year Treasury yield is the benchmark most investors watch, since commercial real estate returns are often measured against it as a spread.
Inflation
Inflation has an indirect but real effect. Cap rates are not directly correlated with inflation, but rising prices tend to push interest rates higher, which widens cap rates.4J.P. Morgan. The Impacts of Inflation on Commercial Real Estate Inflation can also erode NOI if expenses grow faster than rents. The net effect depends on lease structure. Long-term fixed leases suffer most because rental income cannot keep pace with rising costs. Short-term leases and CPI-linked escalations adjust more quickly.
Property-Specific Factors
A building’s age, deferred maintenance, remaining lease term, and tenant credit quality all affect the exit cap rate a buyer will demand. A newly renovated multifamily property with strong occupancy will trade at a tighter cap rate than a dated office building with near-term lease expirations and significant capital needs. In niche asset classes and smaller markets, these property-level factors can outweigh macroeconomic trends.
Why This Number Carries So Much Weight
In a discounted cash flow model, the exit cap rate sets the terminal value, meaning the projected sale proceeds at the end of the holding period. That terminal value, combined with the annual cash flows during the hold, forms the return stream that gets discounted back to present value. The discount rate that makes the net present value equal zero is the IRR.
In most commercial real estate DCF models, terminal value accounts for 50% to 70% of total present value. The exit cap rate assumption therefore has more influence on projected IRR than any single year’s rent growth or expense estimate. A small change can flip a deal from attractive to marginal. That outsized influence is exactly why lenders and equity partners zero in on this input before they look at anything else.2Altus Group.
