About Deal Comparison Calculator

Compare multiple real estate deals side by side. This calculator provides instant results with step-by-step explanations to help you understand the calculation process.

How to use this calculator

  1. Enter the key numbers for each deal you want to compare.
  2. Choose the comparison metric the tool should evaluate, such as cash flow, ROI, or total profit.
  3. Review the side by side results to see which deal performs better on the selected measure.

The formula explained

$$ \text{difference} = \text{deal 1 value} - \text{deal 2 value} $$

  • \(deal 1 value\) = the metric or score for the first real estate deal
  • \(deal 2 value\) = the metric or score for the second real estate deal
  • \(\text{difference}\) = how much one deal is better or worse than the other for the chosen metric

Step by step method

  1. List each property or investment you want to compare and make sure the inputs use the same time period and assumptions.
  2. Enter the figures for each deal into the calculator, including purchase price, income, expenses, and any other required values.
  3. Run the comparison and check the displayed results for each deal side by side.
  4. Use the differences to identify which option is stronger for your goal, such as higher return, lower cost, or better cash flow.

Worked example

Suppose you want to compare two rental properties to see which one produces stronger monthly cash flow.

  1. Deal 1 has monthly income of \(\$2,400\) and monthly expenses of \(\$1,700\), so its cash flow is \(\$2,400 - \$1,700 = \$700\).
  2. Deal 2 has monthly income of \(\$2,250\) and monthly expenses of \(\$1,650\), so its cash flow is \(\$2,250 - \$1,650 = \$600\).
  3. The difference is \(\$700 - \$600 = \$100\), so Deal 1 produces more monthly cash flow.

Answer. Deal 1 is better for monthly cash flow by $100 per month.

Tips and common mistakes

  • Compare deals using the same assumptions, such as loan terms, vacancy, and maintenance.
  • Do not mix monthly and annual numbers unless you convert them first.
  • If two deals look close, test how changes in rent or expenses affect the result.
  • Focus on the metric that matches your goal, not just the biggest purchase price discount.

Frequently asked questions

What kinds of real estate deals can I compare?+

You can compare rental properties, flips, or other investment deals as long as you enter the relevant numbers for each one. The tool is most useful when both deals use the same type of metric, so the comparison stays fair.

Do I need to use the same time period for both deals?+

Yes, the comparison is only meaningful when both deals use the same time period. For example, compare monthly numbers with monthly numbers or annual numbers with annual numbers.

Can this tool help me choose between cash flow and return on investment?+

Yes, but you should decide which metric matters most before comparing. A deal with stronger cash flow is not always the same deal with the highest return on investment.

What should I check if the results look unexpected?+

First, confirm that all values were entered with the correct units and time period. Then review assumptions like expenses, financing, and vacancy, because small input errors can change the comparison a lot.
