Rental Property Calculator – Analyze cash flow & Returns in seconds

Investing in real estate can feel like a lot to figure out, but it really doesn’t have to be. This Rental Property Calculator keeps things simple by showing you the numbers that actually matter. Just drag the sliders and you’ll instantly see how your cash flow, mortgage payment, and returns change.

Try different prices, down payments, rents, or expenses and watch everything update on the spot. It’s a quick way to see if a deal makes sense before you spend time digging deeper. You can test all kinds of “what if” scenarios and compare properties without doing the math yourself.

Whether you’re looking at your very first rental or already have a few under your belt, this tool lays everything out in plain language. No guessing, no spreadsheets. Just clear numbers that help you make decisions with a lot more confidence. And honestly, seeing the numbers jump around as you adjust things is pretty satisfying.

How to use the Calculator

The calculator is built to be straightforward, so you can get answers fast without digging through complicated forms. Each slider controls one part of your rental property scenario:

• Purchase price - Set the amount you expect to pay for the property. This is the starting point for all the numbers that follow;
• Down payment (%) - Choose how much money you want to put down upfront. A bigger down payment usually means a smaller mortgage and lower monthly payments;
• Interest rate - Enter the mortgage rate you expect to get. This helps calculate your monthly payment realistically;
• Loan term - Pick how long you want to finance the loan. A longer term lowers your payment but increases the total interest you’ll end up paying;
• Monthly rent - Estimate what you’ll collect from tenants each month. This is your main source of income from the property;
• Monthly operating expenses - Add up real-life costs like taxes, insurance, repairs, utilities, and management fees. These are the expenses that directly affect your profit.

As you slide each number up or down, the results update instantly. You can immediately see how small changes impact your cash flow, mortgage payment, and overall return, making it much easier to judge whether the property is a solid investment.

What the Rental Property Calculator shows you

Once you adjust the sliders, the calculator breaks everything down into simple, useful numbers:

• Loan amount - This is the total amount you’ll need to borrow after your down payment is taken out. It’s the base for your mortgage calculations;
• Monthly mortgage payment - The amount you’ll pay toward your loan every month. This helps you understand whether the property fits your budget;
• Monthly cash flow - This shows how much money you actually keep after covering all expenses and the mortgage;

Positive cash flow means the property is paying you—not the other way around.

• Annual cash flow - Your expected profit over a full year. This gives you a bigger-picture view of how the property performs;
• Annual NOI (Net operating income) - Your income before mortgage payments. NOI is a key metric investors use to compare properties, estimate value, and judge the long-term strength of a rental.

These results help you quickly understand whether a property is financially strong, risky, or somewhere in between.
