Calculate your true monthly cost after rent specials
Net Effective Rent (NER) is the average monthly rent you pay over the course of a lease after applying specials or concessions, such as:
Free months
Flat-rate discounts
Percentage discounts
It’s the best way to compare different apartment deals, especially when landlords offer promotions that make rents look better than they are.
Just fill in the following:
| Field | Description |
|---|---|
| Lease Term (months) | Total number of months in your lease (e.g., 12, 24). |
| Monthly Rent ($) | Base rent amount before discounts. |
| How many free months? | Months with no rent at all (e.g., first month free). |
| Flat Amount Off ($) | One-time discount applied during the lease (e.g., $500 move-in special). |
Then click Calculate to get:

| Term | Definition |
|---|---|
| Gross Rent | The rent amount listed in the lease (before discounts). |
| Net Effective Rent | The rent averaged over the lease term, factoring in any discounts or rent-free periods. |
Let’s say you sign a 6-month lease at $2,000/month, and you get 1 month free.
Gross Rent: $2,000 × 6 = $12,000
Actual Paid Rent: $2,000 × 5 = $10,000
Net Effective Rent: $10,000 / 6 = $1,666.67/month
Insight: A short-term lease with one free month drastically reduces your average monthly cost!
Lease: 12 months at $2,200/month, $3,000 flat discount.
Total base rent: $26,400
Adjusted rent: $26,400 − $3,000 = $23,400
NER: $23,400 / 12 = $1,950/month
Net Effective Rent (NER) is the average monthly rent you’ll pay over your lease term after factoring in discounts, free months, or other concessions.
It takes your base monthly rent, lease term, any free months, and flat discounts to compute the actual cost per month spread across the entire lease.
It helps you compare different rental deals fairly by revealing the true monthly cost, not just promotional pricing.
You need:
Lease term (months)
Monthly rent
Number of free months
