This property has negative cash flow. You'd pay $135/month out of pocket to own it. Some investors accept this when counting appreciation and principal paydown, but it's a risky bet. Consider a larger down payment, lower price, or a property with higher rent.

How to use this calculator

Enter the property price and expected monthly rent. The calculator immediately shows whether the rent meets the classic 1% rule — a quick sanity check that monthly rent is at least 1% of price.

Fill in the operating costs. Vacancy rate is the percent of the year the unit is unoccupied — 5-10% is typical. Maintenance at 1% of property value per year is a reasonable reserve; set it higher for older properties. Management fee is 8-12% of collected rent if you hire a manager; set to 0 if self-managing (but count your time honestly).

Check Financing to model a mortgage. Investment property loans typically require 20-25% down and run 0.5-1% higher rates than primary residences. Leave unchecked to see the all-cash cap rate.

The Monthly Cash Flow Breakdown at the bottom shows every line item. Review each one — this is where deal analysis happens.

How it works

Three key metrics drive rental property investment decisions. Each answers a different question.

Gross yield is annual rent ÷ property price. It's a quick screening metric but ignores every cost, so it overstates returns. Useful only for comparing properties in the same market.

Cap rate is NOI (net operating income — rent after vacancy and all operating expenses, but before mortgage) ÷ property price. This is the unleveraged return — what you'd earn on an all-cash purchase. Cap rate is how investors compare properties independently of how they're financed. Typical ranges: 3-5% in high-cost coastal cities, 6-10% in most Midwest and Sun Belt markets, 10%+ in high-risk or distressed markets.

Cash-on-cash return is annual cash flow (NOI minus mortgage payments) ÷ cash invested (down payment + closing costs + rehab). This is your actual yield on the money you put in. Leverage amplifies returns: a 6% cap rate can become a 12% cash-on-cash with 25% down financing. But leverage also amplifies losses — if rents fall or costs rise, cash flow can go negative fast.

The 1% rule is a quick filter: monthly rent should be at least 1% of the purchase price. On a $200,000 property that's $2,000 monthly rent. Properties meeting the 1% rule tend to cash flow; properties well below typically don't, even with favorable financing. The rule is harder to find in 2020s markets — many coastal cities have failed the 1% rule for years, while Midwest cities still offer 1.5%+ regularly.

Frequently Asked Questions

Cap rate (capitalization rate) is net operating income divided by property price, expressed as a percent. NOI is rent minus vacancy minus all operating expenses — but before mortgage payments. Cap rate is the unleveraged return on the property itself, useful for comparing properties regardless of how they're financed. A 7% cap rate means the property generates 7% of its value in NOI each year.
