Owning rental property can be a lucrative investment—when managed properly. However, knowing whether a rental property is generating a real profit isn’t always straightforward. From operating expenses to mortgage payments and taxes, many variables affect your bottom line. That’s where a Rental Profit Calculator comes in.

What Is a Rental Profit Calculator?
A Rental Profit Calculator is a tool designed to assess the net profit (or loss) from a rental property after accounting for all income and expenses. It considers factors such as rental income, mortgage payments, maintenance costs, property management fees, insurance, taxes, and more.
The goal is to determine how much money you are left with after all operational and fixed costs are deducted from the gross rental income.
How to Use the Rental Profit Calculator
Using the calculator is simple. Here’s a step-by-step guide:
- Input Monthly Rental Income – Enter the total rent collected per month.
- Enter Monthly Expenses – Include items such as:
- Property taxes
- Mortgage payments
- Insurance
- Repairs and maintenance
- Property management fees
- Vacancy losses
- HOA dues (if applicable)
- Click Calculate – The tool will subtract all your expenses from the income to display your net monthly profit.
- Review Annual Profit – The calculator may also show your estimated annual profit for long-term projections.
Formula Used in the Rental Profit Calculator
The basic formula is:
Net Profit = Total Rental Income − Total Operating Expenses
Where:
- Total Rental Income = Monthly Rent x 12
- Operating Expenses = Sum of all recurring costs (monthly mortgage, property taxes, insurance, repairs, etc.)
Example:
Suppose:
- Monthly rent: $2,500
- Monthly mortgage: $1,200
- Taxes: $200
- Insurance: $100
- Maintenance: $150
- Property management: $250
Total Expenses = $1,200 + $200 + $100 + $150 + $250 = $1,900
Monthly Profit = $2,500 − $1,900 = $600
Annual Profit = $600 x 12 = $7,200
