How Fundology uses it
A fund’s real return is its return with CPIH inflation over the same months taken out. If a fund grew 50% while prices rose 25%, the gain in spending power is 20%, not 50%.
We use CPIH because it is the ONS’s lead measure of consumer inflation and, unlike CPI, includes the costs of owning a home. It is an average across the UK: anyone’s own costs can rise faster or slower.
