🕰️ What Is Inflation?
Inflation is the rate at which the general price level of goods and services rises over time, leading to a decrease in the purchasing power of money. A loaf of bread that cost 10¢ in 1930 might cost $2.50 today due to inflation.

This calculator is ideal for:
- Comparing historical and modern values
- Understanding long-term cost trends
- Adjusting historical salaries for today
- Economic analysis and academic research
- Genealogy or estate research involving old records
If you’re wondering “What was $100 in 1930 worth today?” — this tool provides the answer instantly.
🔢 How Does the 1930 Inflation Calculator Work?
This tool uses Consumer Price Index (CPI) data published by official financial sources to compute the adjusted value of money from 1930 in today’s terms. CPI measures the average change over time in the prices of a basket of consumer goods and services.
✅ Inputs:
- Amount in 1930 (USD)
- Target Year (default is current year)
💻 Steps to Use:
- Enter the amount of money in 1930 (e.g., $50).
- Select the current year or another year for comparison.
- Click “Calculate”.
- The tool displays the equivalent value in the selected year.
🧠 Inflation Adjustment Formula
The calculator uses this formula:
Adjusted Value = Amount × (CPI in Target Year / CPI in 1930)
Where:
- Amount = original money value in 1930
- CPI in Target Year = consumer price index for the current/comparison year
- CPI in 1930 = consumer price index for 1930
📘 Example Calculations
💰 Example 1: What Is $100 from 1930 Worth in 2025?
- CPI in 1930 ≈ 16.7
- CPI in 2025 ≈ 310.0 (estimate)
Adjusted Value = $100 × (310.0 / 16.7) ≈ $1,856.29
So, $100 in 1930 is equivalent to about $1,856.29 in 2025.
📦 Example 2: Value of a $500 Purchase in 1930 Today
Adjusted Value = $500 × (310.0 / 16.7) = $9,281.45
🧾 Example 3: Salary Comparison
If someone earned $2,000 per year in 1930, that would be around $37,125.80 in 2025 dollars, based on inflation alone.
