Rental Property Calculator for Beginners
If you're analyzing your first rental, the jargon can be overwhelming. It really comes down to five numbers. Master these and you can judge almost any deal.
1. Cash flow
What's left each month after rent pays the mortgage and all expenses. Positive cash flow means the property pays you; negative means you feed it.
2. Cap rate
Net operating income ÷ price. A quick way to compare properties regardless of how they're financed.
3. Cash-on-cash return
Annual cash flow ÷ the cash you actually invested. This is your real return on the money you put down.
4. DSCR
Net operating income ÷ loan payments. Lenders want 1.20x+; it tells you how much cushion the deal has.
5. The 1% rule
A fast screen: monthly rent should be near 1% of price. Use it to filter, then run the full numbers.

You don't need to compute these by hand. Start with the free Quick Calculator, and when you're comparing real deals, the full analyzer does all five (plus a 10-year projection) automatically.
