Calculation Assumptions
Gross rental income is monthly rent multiplied by 12.
Vacancy loss reduces gross rent before operating expenses are applied.
Maintenance and management are percentages of gross monthly rent, annualised.
Mortgage payment is the standard fully-amortising principal and interest payment.
Cap rate = annual net operating income divided by purchase price.
Cash-on-cash return = annual pre-tax cash flow divided by total cash invested (down payment + closing costs).
Break-even occupancy is the occupancy level at which cash flow equals zero, assuming the current rent, expenses and financing.
Capital expenditures, income taxes, appreciation and loan paydown are not included. Actual results will differ.
Rental property projections are estimates based on the inputs provided. Actual income, expenses, financing terms and returns may vary because of market conditions, vacancies, tenant turnover, repairs and other factors. This calculator is for informational purposes only and is not financial advice.

Rental Property Calculator
Estimate the potential income and profitability of a rental property before you invest. Understand rental yield, recurring expenses, net rental income and cash flow so you can make a more informed property investment decision.
Understand Your Rental Property Returns
Buying a property to rent out can generate recurring income, but monthly rent alone does not tell you whether the investment is worthwhile. Maintenance, property taxes, vacancy periods, insurance and other costs can reduce the amount you actually keep.
Estimate Rental Income
Calculate the potential monthly and annual rent from a property. Use realistic rent estimates based on similar properties in the same area rather than relying only on advertised rental prices.
Account for Property Costs
Include the expenses you expect to pay as an owner, such as maintenance, property tax, insurance, society charges, management fees and periods when the property may remain vacant.
Evaluate Potential Profitability
Compare the rental income with the property's value and expected costs. This helps you understand gross yield, net yield and potential cash flow before making an investment decision.
How to Use a Rental Property Calculator
Start with the purchase price or current market value of the property. Enter a realistic rent estimate and include the costs that apply to your situation. More complete inputs generally produce a more useful estimate than calculations based on rent alone.
Enter the Property Value
Enter the purchase price or current market value, depending on what you want to evaluate. For a purchase decision, also consider transaction costs, registration, furnishing and initial repairs when estimating your total investment.
Add Expected Rental Income
Enter the rent you reasonably expect to receive each month. Multiply monthly rent by 12 to estimate a full year's rent before accounting for vacancy or missed payments.
Estimate Annual Expenses
Consider property taxes, maintenance, insurance, society or association fees, management costs, owner-paid utilities and an allowance for empty periods or unexpected repairs.
Review the Results
Compare income with expenses and review the estimated yield or cash flow shown by your calculator. Change individual assumptions to see how higher expenses, lower rent or vacancy can affect your expected return.
Important Rental Property Calculations
Different property calculators can report different metrics. These are the main concepts to understand when evaluating the financial performance of a rental property.
Gross Rental Yield
Gross rental yield measures annual rental income in relation to the property's value before deducting running expenses.
It provides a quick way to compare properties, but it does not show how much income remains after expenses.
Net Rental Yield
Net rental yield considers eligible estimated running costs. The precise result depends on which expenses your calculation includes.
For an operating-cost estimate, use annual costs consistently and exclude mortgage payments unless your chosen metric specifically accounts for financing.
Net Operating Income (NOI)
Net operating income estimates the income remaining after rental income adjustments and operating expenses, before property financing costs and income taxes.
Depending on the analysis, effective rental income may account for vacancy and other property income. Mortgage principal and interest are normally kept outside NOI.
Cash Flow
Cash flow shows how much money remains after the income and the expenses included in your calculation are accounted for.
A positive estimate means income exceeds the costs included in the calculation. A negative estimate means you may need to contribute money to cover the shortfall.
Cash-on-Cash Return
This metric compares annual pre-tax cash flow with the cash you invested in the property. It is especially useful when a purchase is financed partly with a loan.
Total cash invested may include the down payment, closing costs and initial work paid from your own funds.
Break-Even Rental Income
Break-even analysis estimates how much rental income is required to cover the costs included in a property budget.
The required rent depends on vacancy, operating expenses, loan payments and other assumptions. This is a planning concept, not a universal measure of investment performance.
Rental Property Calculator Example
Consider a property with an estimated market value of ₹60 lakh and expected monthly rent of ₹25,000. The example below shows how annual expenses can affect its rental yield.
Illustrative Rental Return
These figures are examples for learning, not a prediction of actual income. Assume annual property running costs of ₹40,000. This simplified example does not include loan repayments, income tax or capital appreciation.
| Calculation | Amount or Result |
|---|---|
| Property Value | ₹60,00,000 |
| Expected Monthly Rent | ₹25,000 |
| Annual Gross Rental Income | ₹3,00,000 |
| Assumed Annual Running Costs | ₹40,000 |
| Estimated Income After These Costs | ₹2,60,000 |
| Gross Rental Yield | 5.00% |
| Net Rental Yield on Property Value | 4.33% |
Gross yield = ₹3,00,000 ÷ ₹60,00,000 × 100 = 5.00%. Net yield = (₹3,00,000 − ₹40,000) ÷ ₹60,00,000 × 100 = 4.33%. The net figure here reflects only the assumed costs in this example.
Rental Property Expenses You Should Consider
A realistic rental property analysis includes more than the mortgage payment or the usual monthly maintenance bill. Some costs occur regularly, while others appear only when a tenant moves out or a part of the property needs replacing.
Vacancy and Lost Rent
Allow for periods when the property is empty between tenants, during repairs or while you search for a suitable renter. Do not automatically assume all 12 months will be occupied.
Repairs and Maintenance
Budget for plumbing, electrical work, painting, appliances, cleaning and routine upkeep. Older properties may require a larger maintenance allowance.
Property Tax
Include the property tax or municipal charges paid by the owner. Use the latest available bill or a reliable local estimate rather than assuming the cost will never change.
Insurance
Include relevant building, landlord or other property insurance premiums that apply to your situation. Coverage and pricing vary by location and policy.
Management and Leasing
Consider property management charges, tenant-finding fees, advertising and brokerage costs where applicable. Even when managing the property yourself, occasional leasing costs can still arise.
Society Fees and Utilities
Add apartment association or society charges, common-area costs and utilities you are responsible for paying. Separate owner expenses from amounts paid directly by the tenant.
Major Replacements
Plan separately for infrequent but expensive work, such as replacing appliances, repairing waterproofing or renovating important parts of the property. These costs may not occur every year but can affect long-term returns.
Loan and Purchase Costs
If you are borrowing to buy the property, include principal and interest payments when calculating cash flow. Also consider registration, transaction costs, initial furnishing and repairs when estimating your total cash investment.
How to Evaluate Your Rental Property Results
No single percentage can determine whether a property is a good investment. Location, purchase price, the local rental market, financing terms, building condition and your financial goals all influence the decision.
Compare Properties Using the Same Assumptions
When comparing two rental properties, use the same calculation method and include equivalent expenses. A property with higher advertised rent may produce a lower net return if it costs more to maintain or is likely to remain vacant for longer.
Test Different Rental Scenarios
Calculate a conservative case as well as your expected case. Consider what happens if rent is lower than expected, expenses increase, or the property remains empty for part of the year. This helps you understand how sensitive the investment is to changing assumptions.
Check the Effect of Financing
A property may have positive operating income but negative cash flow after loan payments. Review the interest rate, repayment amount, down payment and other borrowing costs if you plan to use a home or investment-property loan.
Separate Rental Income from Property Appreciation
Rental yield measures income relative to property value. It does not measure how much the property price may rise or fall. Future appreciation can contribute to total investment return, but it is uncertain and should be evaluated separately from rental income.
Consider Taxes and Local Rules
Rental income reporting and allowable deductions depend on the laws that apply to your property and tax situation. A financial calculator generally provides an estimate from the inputs entered; it does not replace local tax rules or professional advice.
Gross Yield vs. Net Yield vs. Cash Flow
These terms are related, but they answer different questions. Understanding the difference helps you interpret rental property calculations correctly.
| Metric | What It Measures | Main Consideration |
|---|---|---|
| Gross Rental Yield | Annual rent compared with property value. | Does not subtract running costs. |
| Net Rental Yield | Rental income after the annual costs included in the formula. | Check which costs are included. |
| Net Operating Income | Operating income remaining after operating expenses. | Normally calculated before loan payments and income tax. |
| Cash Flow | Money remaining after the income and payments included in the calculation. | Loan payments can significantly change the result. |
| Cash-on-Cash Return | Annual pre-tax cash flow compared with total cash invested. | Depends on the investment amount and financing. |
Calculation conventions differ between calculators and financial professionals. Always review the definitions and assumptions used for each reported metric.
Frequently Asked Questions
Find answers to common questions about estimating rental income, rental yield, expenses and property investment returns.
What is a rental property calculator?
A rental property calculator is a financial planning tool that helps estimate income and returns from a property that is rented to tenants. Depending on its features, it can calculate annual rent, rental yield, operating income, expenses, cash flow and other investment measures.
How do I calculate rental yield?
Calculate annual rental income by multiplying monthly rent by 12. Divide annual rent by property value and multiply by 100 to obtain gross rental yield. For a net-yield estimate, subtract the annual expenses covered by your chosen formula before dividing by property value.
What is a good rental yield?
There is no universal yield percentage that makes every property a good investment. Rental yields depend on the city, neighbourhood, property type, purchase price, expected rent, expenses, financing and risk. Compare similar properties using consistent assumptions and consider other investment options before making a decision.
Does rental income mean rental profit?
No. Rental income is the money received from tenants, while rental profit or net income depends on the expenses included in the calculation. Maintenance, property taxes, vacancy, insurance, management charges, financing and tax can reduce the amount you ultimately keep.
Should I include my home loan EMI in the calculation?
Include loan repayments when evaluating cash flow on a financed property. However, net operating income is normally calculated before loan principal and interest payments. Keep these measures separate so the results are not accidentally double-counted or compared incorrectly.
Does the calculator include property appreciation?
Not necessarily. Rental yield focuses on rent relative to property value. Property appreciation is the change in market value over time and should be analysed separately unless the calculator specifically includes an appreciation assumption. Future property prices are uncertain.
Which expenses should I enter for my rental property?
Include the costs relevant to your property, such as maintenance, property tax, insurance, vacancy, management, society fees and utilities paid by the owner. If you want a cash-flow estimate, also account for loan repayments. Review major replacements, transaction costs and taxes separately where they are not included by the calculator.
Can I use this calculator before buying a property?
Yes. Use the expected purchase price, a reasonable estimate of market rent and realistic cost assumptions to compare potential investments. Treat the result as a planning estimate and verify local rents, property condition, ownership costs, financing terms and applicable rules before purchasing.
Does a rental property calculator calculate income tax?
Not every calculator includes tax calculations. Tax treatment depends on your jurisdiction and individual circumstances. For Indian property owners, the official Income Tax Department website is a starting point for checking applicable guidance. Confirm current rules before relying on a tax estimate.
