About RentCalc

RentCalc is a free, privacy-first suite of rental property calculators built for investors, landlords, and house hackers. Every calculation runs locally in your browser — no data is uploaded, no account is required, and no cookies track your inputs.

Our Mission

We believe rental property analysis should be fast, free, and private. Too many tools require sign-ups, collect your financial data, or charge subscription fees for basic calculators. RentCalc gives you the same formulas professionals use, instantly and without barriers.

What We Offer

RentCalc includes nine specialized calculators covering the most important metrics for rental investors: cash flow, cap rate, cash-on-cash return, rental income, gross rent multiplier, Airbnb income, BRRRR strategy, house hacking costs, and rent-vs-buy comparison. Each calculator includes state-level market data, worked examples, and answers to common questions.

Privacy First

Your financial data stays on your device. We use no analytics that track individual inputs, no cookies that follow you across the web, and no server-side processing of your numbers. The calculations happen entirely in JavaScript running in your browser.
