Formula

The calculator uses a basic yet powerful formula:

Price Change = Current Price - Original Price

Percentage Change = (Price Change ÷ Original Price) × 100

This gives you both the dollar amount change and the percentage increase or decrease.

How to Use the House Price Change Calculator

Using this calculator is simple and takes just a few seconds:

1. Enter the Original House Price – This is the amount the house was originally purchased for.
2. Input the Current House Price – This could be the market value, an appraisal value, or your expected selling price.

It’s that easy!

Example

Let’s say you bought your home five years ago for $250,000. Today, the market value is $310,000.

Using the formula:

• Price Change = $310,000 - $250,000 = $60,000
• Percentage Change = ($60,000 / $250,000) × 100 = 24%

So, your home has appreciated by $60,000 or 24% since you bought it.

This information can help you:

• Decide if it’s a good time to sell.
• Refinance your mortgage at a better rate.
• Evaluate the return on investment (ROI) for home improvements.
