Formula & Calculation Methodology
Cash-on-cash return evaluates the annual cash dividend produced by actual cash invested (down payment plus closing expenses). Total ROI expands this metric to incorporate unleveraged property value appreciation.
Worked Example
$350,000 property with $70,000 down, $8,000 closing, $2,600 rent, $1,650 mortgage, $550 opex
Frequently Asked Questions
How does Cash-on-Cash Return differ from Cap Rate?↓
Cap Rate (Rental Yield) assumes the property was bought for 100% cash and ignores financing. Cash-on-Cash return measures the actual leveraged cash return on the specific cash dollars you put down at closing.
Why does leverage (mortgage debt) amplify rental ROI?↓
Financial leverage allows you to control a $350,000 asset with only $78,000 in cash. When the property appreciates 3.5% ($12,250), that entire gain accrues to your $78,000 investment, yielding an extra 15.7% return.
Should I reinvest net rental cash flow or hold an emergency reserve?↓
Experienced real estate investors maintain a dedicated reserve of 3 to 6 months of mortgage payments and operating costs per unit to absorb tenant vacancies or unexpected capital repairs.
What limitation should I know about federal income taxes and depreciation?↓
This calculator evaluates pre-tax cash flow. US real estate offers substantial tax advantages via paper depreciation (27.5-year schedule for residential rentals) which often shields rental income from immediate taxation.
