Lease Expiration Manager

Plan staggered lease renewals and estimate turnover costs from expiration clustering.

About this calculator

The Lease Expiration Manager estimates the annual cost of tenant turnover and gives a benchmark for how expirations should be spread across the year. Ideal Expirations/Month and Peak Month Expirations both come from Total Units divided evenly by 12 — a staggering target, not a read of your property's actual lease calendar, since the calculator has no visibility into individual lease anniversary dates or existing clustering. Annual Expirations is Total Units multiplied by 12 divided by Average Lease Term, which assumes every lease in the portfolio turns over on the same average cadence rather than tracking real dates; a portfolio with lease terms bunched at renewal time will expire far less evenly than this model implies.

Renewal Rate splits those annual expirations into Expected Renewals and Expected Non-Renewals, and only the non-renewals generate cost: Turnover Costs multiplies non-renewals by Turnover Cost per Unit, and Vacancy Loss multiplies non-renewals by the daily rent rate (Average Monthly Rent divided by 30) times Average Vacancy Days. Total Annual Impact is simply those two costs added together. The calculator does not model rent growth on renewed leases, does not vary renewal rate by lease term or season, and does not distinguish a planned vacancy for renovation from an unplanned one — every non-renewal is costed identically.

How to Use This Calculator
  1. Enter Total Units, Average Monthly Rent, and Average Lease Term in months.
  2. Set Renewal Rate % — the percentage of tenants expected to renew their lease.
  3. Enter Turnover Cost per Unit (cleaning, repairs, marketing) and Average Vacancy Days between tenants.
  4. Review Annual Expirations to understand staffing and budget needs.
  5. Check Expected Non-Renewals — the number of units requiring full turnover each year.
  6. Review Total Annual Impact (lost rent + turnover costs) to quantify the financial effect of lease expirations.

Frequently Asked Questions

Does raising rent change how many leases expire each year?

No. Average Monthly Rent has zero effect on Annual Expirations, Expected Renewals, Expected Non-Renewals, or Turnover Costs — those come from Total Units, Average Lease Term, Renewal Rate, and Turnover Cost per Unit. Rent only enters the picture through Vacancy Loss and the resulting Impact as % of Rent, both of which use it to price out lost rent during vacancy.

How is Total Annual Impact calculated?

Total Annual Impact adds two costs together: Turnover Costs, which is Expected Non-Renewals multiplied by Turnover Cost per Unit, and Vacancy Loss, which is Expected Non-Renewals multiplied by the daily rent (Average Monthly Rent divided by 30) times Average Vacancy Days. Renewed leases contribute nothing to either cost, since no turnover event or vacancy occurs for them.

What does "Ideal Expirations/Month" actually mean?

Ideal Expirations/Month is Total Units divided evenly by 12 — a staggering benchmark for how expirations should ideally be spread, not a prediction of your property's actual lease calendar. The calculator has no visibility into individual lease anniversary dates, so if your real leases cluster around a few renewal months, actual monthly expirations will look very different from this even split.

Does a longer Average Lease Term reduce turnover costs?

Yes, indirectly. Annual Expirations equals Total Units times 12 divided by Average Lease Term, so a longer average term produces fewer turnover events per year even though Renewal Rate, Turnover Cost per Unit, and Average Vacancy Days stay the same. Fewer annual turnovers means fewer units incurring Turnover Costs and Vacancy Loss, which lowers Total Annual Impact overall.

Why does increasing the Renewal Rate lower Total Annual Impact?

Raising Renewal Rate shrinks Expected Non-Renewals, and every dollar of Turnover Costs and Vacancy Loss in this calculator is driven entirely by non-renewals — a renewed lease generates no turnover cost and no vacancy days. So a higher renewal percentage directly lowers Total Annual Impact, holding Total Units, Average Lease Term, and the per-unit cost inputs constant.
