Terms of Use

By using this site, you agree to these terms.

Estimates, not advice

The calculator provides estimates for informational purposes only. It is not legal, financial, or tax advice, and it doesn't create any professional relationship. Your lease — and your local laws — always override any number shown here.

Acceptable use

• Use the tool for lawful, personal proration calculations.
• Don't attempt to disrupt the site or misrepresent its output as professional advice.
• Don't scrape the site aggressively; the math is free and the code is simple — just link to us.

Accuracy

We work hard to keep the math correct (it's covered by automated unit tests), but we can't guarantee every result fits every lease. Double-check important figures against your lease terms before paying.

Liability

To the maximum extent permitted by law, we aren't liable for decisions you make based on the calculator's output, including rent disputes or late fees.

Changes

We may update these terms at any time; continued use of the site means you accept the current version.
