This is an estimate, not legal advice. Laws vary by jurisdiction and individual circumstances. Consult a qualified attorney before making any legal decisions.

Estimate the financial cost of ending a lease before it expires. Your actual liability depends on your lease terms and local landlord-tenant law — many jurisdictions require landlords to mitigate damages by re-renting the unit.

Formula

Remaining rent liability ($) = monthly rent × months remaining

Estimated total cost ($) = remaining rent liability + early-termination penalty

How it works

This calculator estimates the worst-case financial exposure of breaking a lease by summing the full remaining rent obligation with any contractual early-termination penalty. In practice, many jurisdictions require landlords to mitigate damages by actively seeking a replacement tenant, which can reduce actual liability; this tool does not model mitigation. The figure produced is a planning maximum, not a guaranteed legal obligation.

Worked example

Worked example

  1. Inputs: monthly rent = $1 500, months remaining = 6, early-termination penalty = $3 000.
  2. Remaining rent liability: $1 500 × 6 = $9 000.
  3. Estimated total cost: $9 000 + $3 000 = $12 000.

Remaining rent liability: $9 000; estimated total cost to break lease: $12 000.

Key terms

Early-termination penalty
A fee specified in the lease that a tenant must pay to the landlord in exchange for being released from the remaining lease term.
Duty to mitigate
The landlord's legal obligation in many jurisdictions to make reasonable efforts to re-let the property after a tenant vacates, reducing the tenant's rent liability.
Lease buyout
An agreed lump-sum payment from tenant to landlord to mutually end the lease before the expiry date.
Subletting
An arrangement where the original tenant rents the property to a third party, potentially avoiding lease-break costs if the lease permits it.

Frequently asked questions

Can I be charged for all remaining months if I break a lease?
In many jurisdictions, landlords have a duty to mitigate damages by making reasonable efforts to re-rent the unit. You may only owe rent for the period the unit sat vacant, not the full term.
What is a lease break fee vs. remaining rent?
Some leases specify a flat early-termination fee (e.g. 2 months' rent) as liquidated damages. Others hold you liable for all remaining rent until a replacement tenant is found. Read your lease carefully.
Does giving proper notice reduce my liability?
Yes. Most leases require advance written notice (often 30–60 days) to minimize penalties. Check your lease for the required notice period.
