Free calculators that help rental property investors and landlords analyze any deal in seconds: cash flow, cap rate, cash-on-cash return, NOI, BRRRR, DSCR, 1031, depreciation, and more. What's different: no sign-up, no paywall, and everything runs in your browser so your numbers never leave your device. Every calculator shows its formula and a worked example, so you're never trusting a black box. Fast, mobile-friendly, one clean page per tool.

Hi everyone, I'm Dan, the maker of CashflowCalcs. I built it because every time I wanted to quickly check whether a rental property actually cash flows, I hit a login wall or a "start your free trial" button just to work out a cap rate. So I made the tool I wanted: free calculators that let you run the numbers on any rental deal in seconds, right in your browser, with no account and no downloads. It covers the whole workflow: deal analysis (cash flow, cap rate, cash-on-cash, NOI), strategies (BRRRR, fix and flip, short-term rental), financing (DSCR loans, cash-out refinance), and taxes (1031, capital gains, depreciation). Every one shows the formula and a worked example, so you're never trusting a black box. It's completely free and ad-supported, and it will stay that way. I'd love your feedback on which calculators are most useful and what I should build next. Thanks for taking a look.

Love that the formulas are visible, that's a huge trust builder. One thing I'd love to see is a side-by-side comparison mode where you can run two properties against each other and see all the metrics on one screen. Would make evaluating competing deals way faster when you're driving around at open houses.
