A cap rate turns one year of net operating income into a value. The division is simple. The work is in the inputs: rent the leases actually support, a fair allowance for vacancy, and expenses from the trailing twelve months rather than a pro forma.
How the math works
Gross rent less vacancy and credit loss is effective gross income. Subtract operating expenses for net operating income, then divide by the cap rate.
$120,000 of rent less 5% vacancy is $114,000. Less $30,000 of expenses, NOI is $84,000. At an 8.0% cap rate, $84,000 divided by 0.08 is $1,050,000.
Cap rate questions, answered
What is a good cap rate?
There is no single good cap rate; it depends on the property type, the tenants, the lease lengths and the market. A newer single-tenant net lease building usually trades at a lower rate than an older strip center with short leases. The right rate comes from recent sales of similar buildings nearby, adjusted for those differences.
Why does half a point matter so much?
Because the cap rate divides the income, small changes move the value a lot. On $84,000 of net operating income, 7.5% gives $1,120,000 and 8.5% gives $988,235, a spread of about $132,000. That is why every Clover State valuation shows a sensitivity table instead of a single rate.
Which expenses belong in NOI?
Operating costs only: property taxes, insurance, repairs and maintenance, owner-paid utilities, management fees and common area costs. Leave out loan payments, depreciation, income tax and one-time capital work such as a new roof. Tenant reimbursements for taxes, insurance and CAM count as income, so include them in gross rent.
What does the implied cap rate tell me?
It tells you what return a quoted price assumes on today’s income. The calculator divides your net operating income by the price you enter. If the quote implies 6.5% and similar sales point nearer 8.0%, the price leans on future rent growth, which an acquisition review tests before you close.
Is this result a valuation?
No. It is arithmetic on the numbers you type, only as good as those numbers. An opinion of value checks the rent against the leases, the expenses against the T-12 and the cap rate against comparable sales. A valuation snapshot does that for one property in five business days from complete documents, from $950.
