CoC ROI

A cash-on-cash return (CoC ROI) is a rate of return often used in real estate transactions that calculates the cash income earned on the cash invested in a property.

Cap rate

The capitalization rate is the rate of return an investor can expect from an investment in real estate, assuming they pay all cash. The cap rate is used to assess the potential of various investment opportunities, giving investors a quick way to analyze a real estate investment. However, it does have limited usefulness as it doesn’t take into account leverage or a mortgage.

NOI

Net operating income (NOI) is a calculation used to analyze the profitability of income-generating real estate investments. NOI equals all revenue from the property, minus all reasonably necessary operating expenses.

REsimpli includes capital expenditures ("CapEx") in our NOI and cap rate calculations for practical purposes helpful to landlords.

Rental Property Formula Example

For this example, we are going to use a property with monthly rent of $2,000, operating expenses of $600 per month, a mortgage payment of $600 per month, a purchase price of $250,000, and total cash invested of $50,000

Cash Flow = ($2,000 + $200) – $600 – $900 = $700 per month

Effective Gross Income z = ($2000 * 12 + $200 * 12) – ($2,200 * 5%) = $24,120 per year

Total Cash Needed = $50,000 + $5,000 + $5,000 + $5,000 + $0 = $65,000

Cap Rate = $16,120 = $250,000 * 100 = 6.45%

Cash-on-Cash Return = $700 * 12 = $65,000 × 100 = 12.9%

These formulas and metrics allow you to analyze both current period returns and project long-term income, experises, and property growth.
