Net effective rent
Rent after accounting for inducements like free rent and allowances, spread over the term.
For example: Hypothetical: two offers with the same face rent have different net effective rents because of different free rent. (Illustration only, not a real deal.)
This is a general industry term with no single official definition. Your lease or contract wording controls.
Example only, not a real client. Say you are choosing between two offices for a five-year lease. One quotes a lower face rent with no extras. The other quotes more per square foot but includes four months free and a larger improvement allowance. When we spread those incentives across the five years, the second office costs less overall, and you also get a better fit-out.
What I’d tell a friend
Compare lease offers on net effective rent and total cost, not the rent number on the first page. A few hours with a simple spreadsheet can change which offer looks best.
Why it matters to you
Free months and allowances make the headline rent look the same across very different offers. Net effective rent spreads those over the term, so it shows which deal actually costs less and which landlord is giving more.
How to use it in your deal
Landlords and buyers should calculate net effective rent for each lease, especially in markets with big inducements. Tenants can use it to compare offers, alongside total occupancy cost. Agree on the method: some people use a simple average, while others discount cash flows. Check whether allowances are paid upfront or over time, and whether any are still owed.
Remember that net effective rent doesn't include operating costs, so add them for budgeting. When renewing, landlords usually start from face rent, so tenants should negotiate inducements again. Write each offer out month by month, including when allowances are paid, and compare the totals.
A deal with free rent at the start is worth more to a cash-tight tenant than the same value spread later. Lenders and appraisers may also look at it, since high inducements can mean face rents overstate income.
Mistakes I see
Mixing gross and net figures. Ignoring unpaid inducements. Using inconsistent methods.
In BC and Vancouver
Lease terms govern; inducements may have tax effects under the Income Tax Act.

How the calculation works
Net effective rent takes the total rent you will pay over the term, subtracts the value of incentives such as free rent and allowances, then spreads the result evenly across the term. That gives you one comparable figure for each offer.
A longer term spreads the incentives across more months, which makes the effective rent look lower. So when you compare offers, make sure the terms are similar, or compare them on total cost as well.
What to include, and what landlords watch
Include the costs you will pay yourself, such as fit-out beyond the allowance, moving, furniture and any period of paying rent at two locations. Those can change the answer.
Landlords watch net effective rent too, because it shows what a deal is really worth to them. Some leases ask you to repay part of the incentives if you leave early, so read that clause before you sign.
