Questions & Answers

As answered by people managing CashflowCalcs and Diffee.

What makes your product unique?

CashflowCalcs's answer

CashflowCalcs brings the whole rental-property analysis workflow into one free, no-sign-up place. Instead of a single cap-rate or mortgage calculator, it offers 18 connected tools spanning deal analysis, investing strategies, financing, and taxes, and every calculator shows its formula and a worked example rather than acting as a black box. It runs entirely in your browser, the numbers you enter never leave your device, and it stays free with no account and no paywall.

Why should a person choose your product over its competitors?

CashflowCalcs's answer

Most rental-analysis tools make you create an account, start a trial, or pay before you can run a single number. CashflowCalcs lets you analyze any deal in seconds with no sign-up, no downloads, and no paywall. It's fast, mobile-friendly, and transparent about the math, so it's ideal for quickly checking whether a deal actually cash flows before you commit time to it or pay for heavier software. It's also honest about its limits: results are clearly labeled as educational estimates, not financial advice.

How would you describe the primary audience of your product?

CashflowCalcs's answer

US-based rental property investors and landlords, especially beginner-to-intermediate investors who want a quick, reliable way to run the numbers on a potential deal. It also fits people weighing their first rental purchase, house hackers, and small-portfolio landlords who need cash flow, cap rate, and financing math without a subscription.

What's the story behind your product?

CashflowCalcs's answer

CashflowCalcs started from a simple frustration: every time its founder wanted to quickly check whether a rental property cash flows, he hit a login wall or a "start your free trial" button just to calculate a cap rate. So he built the tool he wanted, a set of free calculators that run the numbers on any rental deal in seconds, right in the browser, with no account and no downloads. It launched in 2026 and has grown into 18 connected calculators covering the full rental-analysis workflow, and it stays free, supported by ads.

Which are the primary technologies used for building your product?

CashflowCalcs's answer

It's a static site built with Astro and lightweight vanilla JavaScript for the calculators, so pages load fast and run entirely in the browser. It's hosted on Cloudflare Pages, with Cloudflare handling DNS and analytics. There's no backend or database, which is what keeps it fast and private, since the numbers you enter never leave your browser.
