1. What is the House Price Increase Calculator?

This calculator determines the percentage increase in house prices between two time periods using UK government methodology. It helps homeowners, buyers, and investors track property value changes.

2. How Does the Calculator Work?

The calculator uses the standard percentage increase formula:

Where:

• New Price — Current property value in GBP
• Old Price — Original purchase price or previous valuation in GBP

Explanation: The formula calculates the relative change in value compared to the original price, expressed as a percentage.

3. Importance of House Price Tracking

Details: Tracking house price changes helps homeowners understand equity growth, assists buyers in market analysis, and supports investment decisions. The UK government uses similar calculations for housing market reports.

4. Using the Calculator

Tips: Enter both prices in GBP (without commas). For accurate comparisons, ensure prices are from the same property and adjusted for any major renovations if necessary.

Q3: How often should I calculate price increases?
A: Annual calculations are typical, but quarterly may be useful in volatile markets.

Q4: Does this account for regional variations?
A: This basic calculator doesn't. For regional analysis, consult UK HPI regional breakdowns.
