Most lease break calculators give just one number: months remaining × monthly rent. That number is almost always wrong. In most US states, landlords must actively re-rent after a tenant leaves — you only owe rent until they find someone new. This calculator applies your state's actual law — mitigation requirements, notice thresholds, statutory caps, and ETF enforceability — and outputs best case, most likely, and worst case estimates. All 50 states + DC. Free. No signup. No upsell.

Hey Product Hunt 👋 I built this after a close friend had to break a lease and got completely wrong information from two different online calculators — both just multiplied her remaining months by rent and ignored the fact that her state required the landlord to re-rent. The real number was about 40% lower than what she'd been told. Most people in this situation are stressed and time-pressured. I wanted to build something that gave them an honest range — not a scary worst-case number presented as inevitable fact — and explained exactly which levers they can pull to reduce it. Happy to answer any questions about how the state rules dataset works or the calculation logic. And if you're in a lease break situation yourself, try it out — would love to know if the estimate matches your expectations.
