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.
