Historic returns for SS

This table complements the house price index chart above, presenting the data in a more detailed format. It breaks down the information into 20-year, 10-year, 5-year, and 1-year periods, further categorized by property type. For each period, we display both a per annum rate of change and a total rate of change.

The total rate of change represents the overall change over the entire period. The formula for total return is:

Total return = (Index at end of period ÷ Index at start of period) - 1

The per annum rate of change is the annualized rate of change over the period. This is equivalent to the annual bank savings rate you would need to achieve the same total return over the given period. This annualized return is also known as the Compound Annual Growth Rate (CAGR). The formula for CAGR is:

CAGR = (1 + Total return) ^ (1 ÷ Number of years) - 1

Some specific examples:

• Over the past 20 years, Houses have seen a 1.3% annual change when adjusted for inflation. This translates to a total change of 28.5% in real terms.
• Over the past 5 years, Flats have seen a -2.7% annual change when adjusted for inflation. This translates to a total change of -12.7% in real terms.
