Commercial Lease Effective Rent Calculator

Estimate effective commercial rent after free rent and tenant improvement allowance, with scheduled and net-effective cost per square foot.

Tenant-side effective rent

Effective-rent bridge

The calculation spreads net entered rent consideration evenly across the full lease term.

ItemAmount
Scheduled base rent$796,370
Free-rent value($75,000)
TI allowance($200,000)
Net rent consideration$521,370
Effective monthly rent$8,690

This is a simple undiscounted tenant-side comparison. It treats free rent and TI allowance as concessions against scheduled base rent; it excludes operating expenses, commissions, capital timing, and present value.

From face rent to effective rent

Face rent alone does not show the economic impact of free rent or a tenant improvement allowance. Effective rent spreads the entered net rent consideration across the full term.

  • Scheduled rent is calculated from area, starting rate, escalation, and term
  • Free-rent months remove the applicable opening scheduled rent
  • The TI allowance is treated as an entered concession for this planning view
  • Net-effective rent equals net rent consideration divided across the lease term and area

Use one concession definition

Effective-rent conventions vary. Landlord underwriting may include present value, commissions, capital costs, and discount rates that a tenant comparison excludes.

  • State whether the analysis is tenant or landlord oriented
  • Do not double-count TI reimbursement and tenant costs
  • Model operating expenses separately
  • Use discounted cash flow when timing materially affects the decision

Citation facts

  • A simple tenant-side effective-rent estimate can spread scheduled base rent less entered concessions across the full lease term.
  • Free-rent value depends on the scheduled rent during the abatement months.
  • Effective-rent conventions differ, so assumptions should be disclosed with the result.
