If you’re a homeowner considering renting out your property or evaluating how rent compares to your mortgage, a Mortgage to Rent Calculator can offer critical insights. Whether you’re downsizing, investing, or simply assessing affordability, this tool helps determine the equivalent rent value of your current mortgage payments—or how much mortgage a certain rent payment equates to.
🏠 What is a Mortgage to Rent Calculator?
A Mortgage to Rent Calculator converts your monthly mortgage payment into an equivalent rental cost (or vice versa). It’s ideal for:
- Landlords calculating a fair rent based on their mortgage
- Tenants estimating how much they could afford to borrow for a mortgage
- Homeowners downsizing or moving into rented accommodation
- Real estate investors comparing ROI on owned vs. rented properties
This tool bridges the gap between owning and renting, helping you make informed financial decisions about property.
💡 How Does the Mortgage to Rent Calculator Work?
The calculator requires some basic financial inputs. Based on your selection, it converts either your mortgage to an equivalent rent or vice versa. It typically accounts for:
- Monthly mortgage payment
- Interest rate
- Loan term (in years)
- Property value or purchase price (optional)
- Down payment (optional)
It provides an estimate of what the rental equivalent would be if the mortgage payments were redirected to rent—or what mortgage value a given rent could support.
🧮 Formula Used in Mortgage to Rent Calculations
Here are the basic formulas used depending on the calculation type:
1. Convert Mortgage to Rent:
If you have a mortgage, your rent equivalence can be estimated as:
Monthly Rent = Mortgage Payment + Additional Costs (Insurance, Taxes, Maintenance)
Where:
- Mortgage Payment is calculated using the formula:
M = P × (r(1 + r)^n) / ((1 + r)^n - 1)Where:M= Monthly mortgage paymentP= Principal loan amountr= Monthly interest raten= Total number of payments (months)
2. Convert Rent to Mortgage Capability:
If you are renting and want to know how much mortgage you can afford based on rent:
Affordable Mortgage = (Rent – Additional Costs) / Mortgage Factor
Mortgage Factor is derived from interest and term:
Mortgage Factor = (r(1 + r)^n) / ((1 + r)^n - 1)

📊 Example Calculations
Example 1: Mortgage to Rent
You have a mortgage with:
- Loan Amount: $200,000
- Interest Rate: 5% annually
- Loan Term: 30 years
Monthly mortgage =M = 200,000 × (0.004167(1 + 0.004167)^360) / ((1 + 0.004167)^360 - 1)M ≈ $1,073.64
Assuming $200 in additional monthly costs:
Equivalent Rent ≈ $1,073.64 + $200 = $1,273.64
Example 2: Rent to Mortgage
You currently pay rent of $1,500/month
Assuming $200 in taxes/insurance, available for mortgage = $1,300
Interest Rate = 4.5%, Loan Term = 25 years
Using reverse mortgage factor:
Mortgage = $1,300 / 0.00556 ≈ $233,812
