Inflation is the rate at which the general level of prices for goods and services is rising, causing purchasing power to fall. To calculate real value, use the formula: Real Value = Nominal Value / (1 + i)^t, where i is the inflation rate and t is time in years. At a 3% inflation rate, $100 today will have the purchasing power of roughly $74 in 10 years.

Measure your "Real" wealth vs. nominal price increases.

Formula

Real Value = Amount / (1 + Inflation Rate)^Years. Cumulative Inflation = ((1 + Rate)^Years - 1) * 100.

How It Works

Input the current amount of cash or savings you want to analyze.
Set the expected annual inflation rate (historical average is ~3%).
Adjust the time horizon to see the cumulative impact over decades.
Review the "Cost to Buy Same Item" to understand real-world price hikes.

Formula:

Real Value = Amount / (1 + i)^t where i is inflation rate and t is years.

Examples

$100,000 in cash at 3% inflation for 20 years.

Result: $55,368 real value. Nearly half of the purchasing power is lost.

$5,000 at 10% inflation for 5 years.

Result: $3,104 real value. Rapid erosion due to high inflation.

Frequently Asked Questions

What is CPI?

The Consumer Price Index (CPI) measures the average change over time in the prices paid by consumers for a market basket of consumer goods and services.

How can I protect against inflation?

Common hedges include investing in equities, real estate, commodities (like gold), or inflation-protected bonds (e.g., TIPS in the US).

Why does the government want 2% inflation?

Mild inflation encourages people to spend and invest rather than hoard cash, which stimulates economic growth and prevents deflationary spirals.

Is inflation higher for some than others?

Yes. Your personal inflation rate depends on what you buy. If you spend more on tuition or healthcare (which rise faster), your personal inflation is higher.

Key facts

Inflation erodes the purchasing power of cash-based savings over time. Central banks typically target a 2% annual inflation rate as a sign of a healthy economy. Hyperinflation occurs when price increases exceed 50% per month, often leading to currency collapse. Deflation, the opposite of inflation, occurs when prices fall, which can lead to reduced consumer spending.

Trend & Behavior Analysis

The purchasing power curve (Y-axis) follows an inverse exponential decay as years (X-axis) increase. Even at "low" inflation rates of 2%, money loses approximately 50% of its value every 35 years.
