Free Inflation Calculator — CPI & Purchasing Power | NovaCalculator
Calculate the impact of inflation on purchasing power over time using CPI data. Find today's equivalent of past dollar amounts or future value adjusted
Formula
Future Value = Amount / (1 + Inflation Rate)^Years
Inflation reduces purchasing power. What costs $100 today will cost $103 next year at 3% inflation.
Worked Examples
Example 1: Money Loses Value
Problem:$50,000 today with 3% annual inflation for 20 years.
Solution:Purchasing power = $50,000 / (1.03)^20 = $50,000 / 1.806 = $27,683 Lost: $22,317 (44.6%) You need $90,306 in 20 years to match today's $50,000.
Result:44.6% loss in purchasing power
Example 2: Salary vs Inflation
Problem:$60,000 salary, 2% raises, 3% inflation for 10 years.
Solution:Salary after 10 years: $60,000 × 1.02^10 = $73,158 Inflation-adjusted $60,000: $80,635 Real income declined by $7,477 2% raises don't keep pace with 3% inflation!
Result:Lost $7,477 purchasing power
Example 3: College Costs
Problem:$30,000/year tuition today, 5% inflation, child goes in 15 years.
Solution:Future cost = $30,000 × (1.05)^15 = $30,000 × 2.079 = $62,367/year For 4 years: ~$270,000 Plan for future costs, not today's!
Result:$62,367/year in 15 years
Frequently Asked Questions
What is inflation?
The rate at which prices increase over time, reducing purchasing power. 3% inflation means what costs $100 today will cost $103 next year, or that $100 next year only buys what ~$97 could today.
What causes inflation?
Increased money supply, strong demand vs limited supply, rising production costs, or expectations. Central banks target ~2% inflation for healthy economy.
How does inflation affect savings?
Cash loses purchasing power. $10,000 at 3% inflation becomes worth $7,440 in 10 years. Invest to outpace inflation.
What is the Rule of 72?
72 ÷ inflation rate = years to halve purchasing power. At 3% inflation, money loses half its value in 24 years.
How do I protect against inflation?
Invest in assets that grow faster than inflation: stocks (~10%), real estate, I-Bonds, TIPS. Avoid holding excess cash.
How is inflation measured?
Consumer Price Index (CPI) tracks basket of goods. Producer Price Index (PPI) measures wholesale. Personal Consumption Expenditures (PCE) is Fed's preferred measure.
What is real vs nominal return?
Nominal: stated return. Real: return after inflation. 7% return with 3% inflation = 4% real return. Real return determines actual wealth growth.
