House Price Percentage Increase

A positive number is appreciation; a negative number means the current value is below the purchase price.
What is a house price percentage increase calculator?
A house price percentage increase calculator measures how much a home's value has risen between two figures, expressed as a percentage of the purchase price. It answers the question: by what percentage did this home appreciate? It is used for refinancing, sale decisions, and equity assessment.
The formula is ((current value − purchase price) / purchase price) × 100. The appreciation is divided by the purchase price, so the result is always relative to your entry point. The house price percentage increase calculator applies this automatically and returns both the percentage and the dollar appreciation.
Tracking the house price percentage increase matters because a flat dollar gain hides the real return. A 60,000-dollar appreciation means very different things on a 300,000-dollar home and a 3,000,000-dollar home. Expressing the change as a percentage lets you compare appreciation across properties, markets, and time horizons.
