Investing in rental properties can be one of the best ways to build long-term wealth, but let’s be honest—it’s not always easy to figure out which properties will actually make you money. Running the numbers by hand can be time-consuming, and guessing isn’t a strategy. That’s why we’re excited to introduce the RBH Rental Property Calculator, a tool designed to help investors quickly and accurately analyze rental property deals.
Whether you’re new to real estate or an experienced investor looking to fine-tune your buying decisions, this tool can help you maximize cash flow and avoid bad investments. Let’s break down what it does, how it works, and why you should be using it for every rental property purchase.
1. Why Rental Property Analysis Matters
Buying a rental property isn’t just about finding a good deal—it’s about making sure the numbers actually work. You wouldn’t buy a business without knowing if it’s profitable, right? The same logic applies to rental property investing.
What Happens When You Skip the Numbers?
- You overestimate rental income and end up with negative cash flow.
- Hidden costs eat away at profits, leaving you with little to no return.
- Your financing terms don’t work in your favor, leading to higher-than-expected expenses.
What the RBH Rental Property Calculator Can Do
This tool takes the guesswork out of investing by breaking down key financial metrics like:
- Cash flow – How much money you’ll pocket each month after expenses.
- Cap rate – A percentage that shows the return on investment.
- Cash-on-cash return – How well your initial investment is working for you.
- Debt service coverage ratio (DSCR) – A number that helps lenders assess risk.
2. How the RBH Rental Property Calculator Works
The RBH Rental Property Calculator is designed to be user-friendly while still providing detailed financial insights. You don’t need an accounting degree to use it—all you need are a few key details about the property you’re analyzing.
Step-by-Step Breakdown
Step 1: Enter Basic Property Details
- Purchase price
- Down payment percentage

Step 2: Estimate Rental Income

This means you can quickly determine whether a property is worth your time or a potential money pit.
3. Key Metrics Every Investor Should Know
If you’re going to be a successful rental property investor, you need to understand the numbers behind the deal. Here’s what the RBH Rental Property Calculator helps you analyze:
Cash Flow – The Monthly Profit That Actually Hits Your Pocket
Cash flow is the amount of money left over after all expenses are paid. It’s the lifeline of any rental property investment.
Formula:
Cash Flow = Total Rental Income – Total Expenses
A property might look great on paper, but if the cash flow is negative, it’s not a smart buy.
Cap Rate – A Quick Way to Compare Investment Returns
Cap rate measures the return on an investment without considering financing. It’s useful when comparing properties side by side.
Formula:
Cap Rate = (NOI / Purchase Price) x 100
A higher cap rate generally means a better return, but it’s important to factor in risk and location.
Cash-on-Cash Return – How Hard Your Investment Dollars Are Working
This metric shows how much return you’re making on your actual cash investment (down payment and closing costs).
Formula:
Cash-on-Cash Return = (Annual Cash Flow / Total Cash Invested) x 100
If your cash-on-cash return is too low, you may want to rethink the deal or find better financing terms.
4. Who Can Benefit from the RBH Rental Property Calculator?

6. Common Mistakes Investors Make When Evaluating Rentals
Even experienced investors make mistakes when analyzing rental properties. Here are some of the most common pitfalls and how the RBH Rental Property Calculator helps you avoid them.
Underestimating Expenses
Many investors forget about things like:
- Major repairs
- Property management fees
- Rising property taxes
Our calculator ensures you account for all potential costs so you’re never caught off guard.
Ignoring Vacancy Rates
No rental is occupied 100% of the time. Failing to account for vacancy can throw off your cash flow projections.
Not Factoring in Loan Terms
The difference between a 5% interest rate and a 7% interest rate could mean hundreds of dollars in extra costs each month.
Our calculator automatically factors in financing terms so you see the real impact of loan costs.
