Lease Break Cost Calculator
Estimate the total financial cost of breaking a lease early, including break fees, ongoing rent liability, advertising, and reletting costs.
Formulas Used
Weekly Rent = (Monthly Rent × 12) ÷ 52
Daily Rent = Monthly Rent ÷ 30.4375
Remaining Lease Days = Lease End Date − Break Date
Proportion Remaining = Remaining Days ÷ Total Lease Days
Fixed Break Fee = Break Fee Weeks × Weekly Rent
Rent Liability = min(Relet Weeks, Remaining Weeks) × Weekly Rent
Total Gross Break Cost = Fixed Break Fee + Rent Liability + Advertising Cost
Net Break Cost = Total Gross Break Cost − min(Bond, Total Gross Break Cost)
Assumptions & References
- A month is assumed to be 30.4375 days (365.25 ÷ 12) for daily rent calculations.
- The fixed break fee (in weeks of rent) reflects common lease clauses; check your specific lease agreement as this varies by jurisdiction and contract.
- Rent liability is capped at the lesser of the estimated vacancy period or the remaining lease term — you are not liable for rent beyond the original lease end date.
- The bond offset assumes the landlord applies the full bond toward outstanding costs; actual bond return depends on property condition and local tenancy law.
- Advertising and reletting fees vary by agent and market; obtain quotes from your property manager for accuracy.
- This calculator provides an estimate only. Actual costs depend on your lease agreement, local residential tenancy legislation, and negotiation with your landlord.
