Gross Income Calculator for Rentals | Tim Tepes, Lehigh Valley

Real Estate Calculators

How much gross income does this building produce, and does it fill the cap rate?

Gross income is the top of every deal analysis: what the building can bring in before a dollar of expenses. This calculator turns monthly rent per unit, the unit count, and your vacancy assumption into the scheduled and effective gross income, then checks the income against the asking price at a target cap rate, so you know whether the rent sheet even supports the price before you look at expenses.

Income and the price tag

The income yield you want on the full price, before debt.

Scheduled gross income
$57,600
Effective gross income (after vacancy)
$54,720
Monthly rent roll
$4,800
Net operating income needed to hit your target cap
$29,250

The instant smell test: a 4-unit at $1,200 a unit grossing near $57,600 against a $450,000 ask needs most of that income to survive expenses before it supports a 6.5% cap. If expenses typically run 40 to 50 percent of effective gross income, the gap shows up fast. That is the conversation Tim starts with on every small multifamily listing.
