Standard formulas, shown openly
Each calculator states the exact formula it uses and links the source. Cap rate divides net operating income by price; cash-on-cash return divides cash flow by the cash you invested; DSCR divides NOI by annual debt service. Nothing is hidden behind a black box — you can see how every number is produced and reproduce it yourself.
How the calculators work together
Start with NOI to establish a property's earning power, then run cap rate and rental yield to judge the price, and cash-on-cash return and DSCR to test the financing. Screen listings fast with the gross rent multiplier and price-to-rent ratio, and model a renovation with the fix-and-flip profit calculator. Each page links to the related tools, so you can move from "what does it earn" to "does the loan work" in a couple of clicks.
Estimates, not financial advice
These tools apply standard real-estate formulas to the figures you enter. Real returns depend on accurate rent, expense and vacancy assumptions, financing terms, taxes and market conditions, so treat every result as a well-founded starting point rather than a guarantee. For investment, financing or tax decisions, run your own numbers and speak to a qualified professional.
