Net Effective Rent vs Gross Rent
Short answer
Gross rent is the face rent stated in the lease. Net effective rent is the average monthly cost after concessions are spread over the lease. Formula: (total face rent − concessions) ÷ lease months = net effective rent. Example: ($24,000 − $2,000) ÷ 12 = $1,833.33. Budget on face rent; compare deals on effective rent.

Gross rent: the face figure
If you ask what gross rent is, the answer is simple: gross rent — often called face rent — is the monthly rent stated in the lease before any concession. It is the amount due in an ordinary month, the figure a rent increase is normally calculated from, and the figure your monthly budget must handle. If the lease says $2,000 per month, your gross rent is $2,000, whatever the advertising says.
Net effective rent: the average after concessions
Net effective rent means the average monthly cost once concessions are spread across the whole lease. Net effective rent spreads concessions across the whole lease: (total face rent − total concessions) ÷ lease term. Concessions include free months, waived fees, and cash credits stated in the lease or offer. In the example above — $2,000 × 12 = $24,000 gross, minus one free month of $2,000, = $22,000 net, ÷ 12 = $1,833.33 effective. The Net Effective Rent Calculator runs this for any combination of free months and other concessions.
Why the distinction matters
In a net rent vs gross rent comparison, the effective figure helps you compare total value, while the face figure is what you actually pay each month.
- Comparing deals: a $2,000 lease with a free month and a $1,850 lease with no concession are closer than their face rents suggest — $1,833.33 effective vs $1,850. Compare effective rents for value, face rents for cash flow.
- Budgeting: the effective figure is an average, not a bill. In non-free months you pay the face rent, so a budget built on $1,833.33 will be short by $166.67 in those months.
- Renewals and increases: a renewal increase is normally applied to the face rent, not the effective rent, so the effective discount does not carry forward automatically — check the renewal terms.
- Early exit: a concession may be repayable or forfeited if the lease ends early. The lease, not the advertisement, decides.
Net effective rent is not a bill and not a second rent; it is an average that takes the total actually paid for rent over the lease, after concessions, and spreads it evenly, so two leases with different concession structures can be compared on total value. Gross rent, meanwhile, is normally the base from which a renewal rent is calculated, subject to the lease terms.
Common traps
Advertisements lead with the effective rent because it looks lower. Always ask for the face rent, the number and timing of free months, and whether any concession must be repaid on early termination. A deal with a lower effective rent but a higher face rent can strain monthly cash flow even while winning on total cost — and a deal with a lower face rent but no concession can be the safer monthly choice. Run both figures before signing.

The formula, with every concession type
The general formula is: net effective rent = (face monthly rent × lease months − total concessions) ÷ lease months. Total concessions is the sum of everything that reduces rent over the lease: free months, waived fees that would otherwise be rent, and cash credits applied to rent. Fees that are not rent — such as a parking fee you still pay — should not be deducted as a concession unless the offer states that they are waived as part of the rent deal; otherwise the effective figure understates what you pay. Keep a separate list of concessions and their values, so the calculation can be checked line by line.
Example with mixed concessions: face rent $2,200, lease 12 months, one free month worth $2,200, plus a $600 rent credit. Total face rent: $2,200 × 12 = $26,400. Total concessions: $2,200 + $600 = $2,800. Net total: $26,400 − $2,800 = $23,600. Net effective rent: $23,600 ÷ 12 = $1,966.67. The monthly saving against face rent is $233.33, and the total saving over the lease is $2,800. If the free month falls in month one, the cash pattern is $0 in month one and $2,200 in each other month except for the credit month; if the credit is spread, the pattern differs again. The average is the same, but the cash-flow pattern is not, which is why the lease should state when each concession applies.
Worked comparisons across lease lengths
| Offer | Face rent | Term and concession | Net effective rent |
|---|---|---|---|
| A | $2,000 | 12 months, 1 free month | $1,833.33 |
| B | $1,850 | 12 months, no concession | $1,850.00 |
| C | $2,100 | 12 months, 2 free months | $1,750.00 |
| D | $1,950 | 24 months, 1 free month | $1,868.75 |
| E | $2,400 | 6 months, half a month free ($1,200) | $2,200.00 |
Check Offer D: total face rent $1,950 × 24 = $46,800, minus one free month of $1,950, gives $44,850, divided by 24 gives $1,868.75. Check Offer E: $2,400 × 6 = $14,400, minus $1,200, gives $13,200, divided by 6 gives $2,200. The ranking on effective rent is C first at $1,750, then A at $1,833.33, then B at $1,850, then D at $1,868.75, then E at $2,200. The ranking on face rent is almost the reverse for the top offers: B is cheapest by face rent at $1,850, yet C, with the highest face rent among the 12-month offers at $2,100, wins on effective rent because of two free months. A renter with tight monthly cash flow might still prefer B, because $1,850 is due every month, while C requires $2,100 in ten months and $0 in two months. Value and cash flow point in different directions, and both must be weighed.
Cash-flow pattern: why the average is not a bill
Take Offer A again: $2,000 face rent, 12 months, one free month. Suppose the free month is month six. The payment pattern is $2,000 in months one to five, $0 in month six, and $2,000 in months seven to twelve. A budget built on the effective rent of $1,833.33 would be short by $166.67 in each of the eleven paying months, and would hold $1,833.33 unspent in the free month. Over the year the totals match — $22,000 either way — but month by month they do not. The safe budgeting method is to budget $2,000 every month, treat the free month as a windfall that goes to savings or to the next month's buffer, and never let the average set the monthly automatic payment or payment amount.
Renewals, increases, and early exit
At renewal, the starting point is normally the face rent, not the effective rent, unless the renewal terms state otherwise. Example: a lease at $2,000 face rent with one free month has an effective rent of $1,833.33 in year one. If the renewal rent is set at the face rent plus an increase — say the lease provides for a renewal at $2,100 — then year two has no free month unless a new concession is offered, and the effective rent in year two is $2,100, not $1,833.33 plus a small rise. The year-one discount does not carry forward by itself. Before signing, ask what the renewal rent will be based on, whether any concession repeats, and get the answer in the renewal clause or in writing.
Early exit is the second place where concessions bite. Some leases require repayment of a concession, in whole or in part, if the tenant leaves before the lease term ends; others simply forfeit the remaining concession. Example: a tenant on Offer C, with two free months worth $4,200, leaves after six months. If the lease requires repayment of the concessions already taken, the tenant may owe back the free months already enjoyed, which can erase the apparent saving. If the lease instead forfeits only the unused concession, the tenant keeps the saving on the months already lived. The lease decides, and the difference can be thousands of dollars, so read the early-termination and concession-repayment clauses before relying on an effective rent. For any state rent rule that may affect a renewal or an increase, check the official source for your city and state, and see the Rent Rules Explained pillar guide for the rules scoped on this site.
What net effective rent does not tell you
Judged on effective rent alone, you learn nothing about the quality of the home, the total cost including utilities and parking, or whether the face rent is affordable against income. A home with a low effective rent but a high face rent can still breach an affordability ceiling in paying months, and a home with a higher effective rent but a lower face rent can be easier to live with month to month. Pair the effective comparison with a face-rent affordability check — the Rent Affordability Calculator runs that test — and with a full total-cost comparison using the Rent Compare Calculator. Effective rent also says nothing about what happens after the lease ends, about deposit return, or about whether a concession is genuinely free or is recovered through a higher face rent. A face rent set $150 above comparable homes, with a concession worth $150 a month on average, is not a discount at all; it is a higher rent presented as a deal. Compare face rents with comparable homes first, then concessions second.

Frequently asked questions
What is net effective rent?
Total face rent minus concessions, divided by the lease term — the average monthly cost across the lease.
What is gross rent?
The face monthly rent stated in the lease, before concessions — the amount due in an ordinary month.
Which figure should I budget on?
The face rent, because that is what you pay in non-free months. Use the effective rent only to compare the total value of competing deals.
How do I calculate net effective rent with two free months?
Subtract both free months from total face rent, then divide by the lease term. For $2,100 over 12 months with two free months: ($25,200 − $4,200) ÷ 12 = $1,750. The Net Effective Rent Calculator runs this for any number of free months.
Does a free month reduce my deposit or my renewal rent?
Not automatically. A deposit, where one applies, and a renewal rent are normally based on the lease terms and the face rent, not on the effective average. Check the lease for each figure separately, and check the official source for any deposit or renewal rule in your area.
Is net effective rent the same as discounted rent?
Not exactly. A discounted rent is a lower monthly bill each month; net effective rent is an average that may reflect a free month in only one month. A $100 monthly discount and a $1,200 single credit give the same effective rent over 12 months but very different monthly bills.
Why do landlords advertise effective rent instead of face rent?
Because the effective figure looks lower and makes the total deal easier to compare at a glance. That is a legitimate comparison tool, but it should never replace the face rent in a budget, because the face rent is what is due in paying months.
What if a concession is spread over the lease instead of given as a free month?
Then each month's bill genuinely falls by the spread amount. A $1,200 credit spread over 12 months reduces a $2,000 face rent to a $1,900 monthly payment, which is easier to budget than a single free month, even though the effective rent is $1,900 in both structures only if the credit is the sole concession — check the arithmetic for your own combination.
Can effective rent be lower than I can actually afford month to month?
Yes, in the sense that matters: if the face rent exceeds your monthly capacity, the average will not save you in paying months. Always test the face rent against income and cash flow first, and use effective rent only to rank deals that already pass the face-rent test.
