What is the formula for calculating future inflation value?

The future value adjusted for inflation is: `FV = PV × (1 + i)^t`, where `PV` is present value, `i` is annual inflation rate, and `t` is number of years.

What is purchasing power?

Purchasing power is the quantity of goods or services that can be bought with one unit of currency. As inflation rises, purchasing power decreases.

What is the Consumer Price Index (CPI)?

The CPI is an economic indicator published by the US Bureau of Labor Statistics that measures average price changes over time for a standard basket of consumer goods and services.

How can investors protect their wealth against inflation?

Investors protect against inflation by holding inflation-resistant assets such as equities, real estate, Treasury Inflation-Protected Securities (TIPS), and commodities.

What is the difference between nominal returns and real returns?

Nominal return is the raw percentage gain of an investment, while real return subtracts the inflation rate to show actual purchasing power growth (`Real Return ≈ Nominal Return - Inflation`).

How Does Inflation Erode Purchasing Power Over Time?

Inflation is the general rise in prices of goods and services over time, which reduces the purchasing power of money. For example, at an average 3% annual inflation rate, $100 today will only buy about $41 worth of goods in 30 years ($100 / (1.03)^30 = $41.20).

Mathematical Formula & Equations

Calculates the future or historical value of money over time using the Consumer Price Index (CPI) and annual inflation rates.

\[ V_t = V_0 \times (1 + r)^t = V_0 \times \frac{\text{CPI}_t}{\text{CPI}_0} \]

Calculation Example

$100 in 2000 adjusted for average 2.5% annual inflation over 26 years: $$V_{2026} = 100 \times (1.025)^{26} = \$190.03$$
