Built to show its work

Most rental calculators give you a number and ask you to trust it. These show the working: every assumption is visible, and operating performance is kept separate from financing so you can see which one is carrying the deal.

Nothing is stored. Your numbers stay in your browser, and you can copy a link to share any scenario with a partner, lender or agent. The tools are free and educational, so verify rent, costs and financing before you make an offer.
