Formula and method

For a 12-month lease at 2,000 per month, one free month, monthly operating costs of 200 and a one-time allowance of 1,200, net effective rent is about 1,533.33 per month.

Monthly net = [rent × (term − free months) − monthly costs × term − allowance] / term

Assumptions and limitations

  • This is the landlord net-receipts view: operating costs and the tenant allowance reduce rent received. It is not simply the tenant monthly payment after a free-rent offer.
  • The lease term and rent-free duration use months internally. Rent-free duration may not exceed the lease term. Operating costs continue during all modeled months.
  • The allowance is paid once across the whole lease; operating costs recur each month. No discount rate, escalation, vacancy after the lease or tax effects are included.
  • Zero or negative net effective rent is retained when concessions and costs equal or exceed receipts. Use one consistent currency for every amount.
  • Area mode divides the same cash flows by property area. The base rent per area is monthly and the allowance per area is a one-time amount.

Common questions

Why can this be lower than advertised effective rent?

This model also subtracts the landlord operating costs and tenant allowance. A tenant-facing effective-rent quote may subtract only rent-free months.

References

Bookify allows zero and negative net rental receipts and limits rent-free duration to the lease term.
