Quick Answer

An inflation calculator shows how prices grow at a steady annual inflation rate using future cost = amount × (1 + inflation)^years, and what that amount will be worth in today's terms by dividing by the same factor. For example, at 3.5% a year something costing $1,000 today costs about $1,734 in 16 years (a 73.4% rise), and $1,000 received in 16 years buys only what $577 buys now. Use it for long-term goals, salary comparisons and real-return checks; it applies one constant rate you choose, whereas actual CPI inflation varies from year to year.

How This Calculation Works

Values calculate dynamically in real-time as you enter figures or adjust sliders.
The equation on the right is exactly what the calculator runs — check any result by hand.

Core Equation

Future Cost (Inflation-Adjusted):
  FV = PV × (1 + i)ⁿ
  Where i = annual inflation rate, n = years

Purchasing Power of Today's Amount:
  PP = PV / (1 + i)ⁿ

Cumulative Price Rise:
  Rise% = (FV − PV) / PV × 100

Real Return (Investment after Inflation):
  Real Return = ((1 + Nominal Rate) / (1 + Inflation Rate)) − 1

How to Use the Inflation Calculator

Quick 3-step guide for accurate and fast calculations

STEP 01

Enter your current money / expense amount

In the Inflation Calculator, fill in Current Money / Expense Amount, Annual Inflation Rate and Number of Years in the Future.

STEP 02

Read your future cost of same lifestyle

The Inflation Calculator instantly shows Future Cost of Same Lifestyle, Future Purchasing Power of Current Amount, Cumulative Price Rise (%) and Average Yearly Depreciation, updating as you type.

STEP 03

Compare scenarios

Change Annual Inflation Rate to see how it affects Future Cost of Same Lifestyle, then check the formula below to verify the math.

Specific Instructions:

Enter today's amount (a price, expense or savings balance), the annual inflation rate you expect and the number of years ahead. The calculator shows the future cost of the same purchase, the future purchasing power of today's amount, the cumulative price rise in percent and the average increase per year.

Inflation Calculator Formula

The Inflation Calculator uses the following formula, calculated in your browser as you change the inputs:

Future Cost (Inflation-Adjusted): FV = PV × (1 + i)ⁿ Where i = annual inflation rate, n = years Purchasing Power of Today's Amount: PP = PV / (1 + i)ⁿ Cumulative Price Rise: Rise% = (FV − PV) / PV × 100 Real Return (Investment after Inflation): Real Return = ((1 + Nominal Rate) / (1 + Inflation Rate)) − 1

Worked Example: Inflation Calculator

Amount: $1,000 in 2010 | Annual inflation: 3.5% | To year 2026 n = 16 years Inflation-adjusted value = $1,000 × (1.035)¹⁶ = $1,734 Meaning: $1,000 in 2010 = $1,734 today; or today's $1,000 has the same buying power as $577 in 2010

SIP vs Lump Sum Investing: How They Compare

A lump sum puts all your money to work at once, so it tends to earn more when markets rise steadily, while a SIP (systematic investment plan) invests a fixed amount every month, which spreads your entry price and suits people investing from a monthly income. Neither is always better: lump sum wins on time in the market, and SIP wins on discipline and lower timing risk.

Frequently Asked Questions — Inflation Calculator

What does inflation mean for my savings?

Inflation reduces the real value of cash savings. If inflation runs at 4% per year and your savings account earns 2%, your real purchasing power is shrinking by approximately 2% per year. Over 10 years, money that earned 2% while inflation was 4% would have only 82% of its original buying power.

What is a normal inflation rate?

Most central banks (including the US Federal Reserve and European Central Bank) target a 2% annual inflation rate as optimal for economic stability. In practice, US inflation has averaged about 3.3% per year since 1914. Periods like 2021-2022 saw inflation surge above 8-9% — unusually high by modern standards.

How do I protect my money from inflation?

To protect purchasing power against inflation, invest in assets that historically outpace it: equities (stock market) have averaged ~10% annually vs ~3.3% inflation; real estate tends to appreciate with inflation; inflation-protected bonds (TIPS in the US, IIBs in India) are specifically designed to maintain purchasing power; gold is a traditional inflation hedge though it underperforms equities over the long term.
