> The net effective rent calculator works out the true average rent of a lease after concessions such as free months and a tenant cash allowance – per month, per year and per square foot.

## Inputs

- Lease term (months)
- Monthly rent
- Rent-free months
- Tenant cash allowance
- Area (optional) (ft²)

## Results

- Total rent paid
- Net effective rent (monthly)
- Net effective rent (annual)
- Discount from the asking rent
- Net effective rent per ft² per year

## Formula

```
Total rent paid = monthly rent × (lease months − free months) − cash allowance
Net effective rent (monthly) = total rent paid ÷ lease months
```

## Explanation

Landlords often advertise the "gross" rent but offer one or two months free. Net effective rent spreads those concessions over the lease so you can compare listings fairly.

### How to use the Net Effective Rent Calculator

- **Lease term**
- **Monthly rent**
- **Rent-free months**
- **Tenant cash allowance**
- **Area (optional)**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter the lease term, monthly rent, number of free months, any cash allowance and the area.

### Tips

- Get a written loan estimate and compare the APR, not just the interest rate.
- Include property tax, insurance, HOA fees and maintenance in your monthly budget.
- A larger down payment lowers the payment and can remove mortgage insurance.
- Rates change daily – use a current quote for the most accurate result.

### Common mistakes to avoid

- Looking only at the monthly payment instead of the total cost of the loan.
- Forgetting closing costs and fees.
- Assuming home prices always rise.

### What each result means

- **Total rent paid** = [Monthly rent]×([Lease term] - [Rent-free months]) - [Tenant cash allowance]
- **Net effective rent (monthly)** = [Total rent paid]÷[Lease term]
- **Net effective rent (annual)** = [Total rent paid]÷[Lease term]×12
- **Discount from the asking rent** = (1 - [Net effective rent (monthly)]÷[Monthly rent])×100

### Example values
