Illustrative net exposure
~$8,900
The tool multiplies monthly rent by months remaining, then scales that obligation by (100% − mitigation%) to reflect expected re-renting or legal mitigation. It adds any early-termination and reletting fees from your lease or negotiation notes. If you choose to apply a security deposit, that amount offsets the subtotal up to the subtotal (it cannot go negative). The result is an illustrative cash exposure figure—not a court judgment.
Low/high bands scale the net estimate for quick sensitivity—actual disputes may include interest, attorney fees if allowed, and separate deposit claims.
