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\n= $50,000 / 1.806\n= $27,683\n\nLost: $22,317 (44.6%)\n\nYou 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\nInflation-adjusted $60,000: $80,635\n\nReal income declined by $7,477\n\n2% 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\n= $30,000 × 2.079\n= $62,367/year\n\nFor 4 years: ~$270,000\n\nPlan 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.
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.
