In a Massachusetts eviction, what you "owe" can shrink — or flip — once habitability abatement and security-deposit triple damages are counted. Enter your numbers and see your net exposure. Free, no sign-up.
Many late-fee and "use and occupancy" add-ons are limited by law or the lease. We include what you enter as the landlord's claim.
Breach of the warranty of habitability can reduce the rent you owe (rent abatement) when the landlord knew and didn't fix it. This estimate applies a rough abatement to the rent owed for illustration only.
Under c. 186 §15B, strict violations (no receipts, no separate MA account, no 5% interest, late return) can mean triple the deposit plus interest, fees, and costs — often more than the back rent. "Not sure" is common and worth checking.
This calculator is an educational illustration based on the figures you enter — not a legal opinion, a settlement value, or a prediction of any outcome. Habitability abatement and security-deposit damages depend on the specific facts, what the landlord knew, strict statutory compliance, and a judge's findings; the percentages used here are rough illustrations only. Actual results vary. Confirm everything with the statutes (M.G.L. c. 186, c. 239) and a licensed attorney before relying on it. Using this tool does not create an attorney-client relationship, which forms only on a signed limited-scope engagement.
