Inflation Calculator

What today's money will be worth after years of inflation.

Overview

Calculates the eroding purchasing power of money over time and projects future costs of living based on historical inflation rates.

Formula & Calculation Method

Future Value = Present Value × (1 + Inflation Rate)^Years

Determines how much future currency is needed to purchase a basket of goods costing a given amount today.

Worked Example: ₹1,00,000 Purchasing Power in 15 Years at 6% Inflation

Inputs: Current Amount = ₹1,00,000 | Inflation Rate = 6% p.a. | Duration = 15 Years

  • Inflation compounding factor = (1 + 0.06)^15 = (1.06)^15 = 2.3965
  • Equivalent future cost = ₹1,00,000 × 2.3965 = ₹2,39,655
  • Loss of purchasing power = Today's ₹1,00,000 will only buy ₹41,727 worth of goods in 15 years

Summary: Present Value = ₹1,00,000 | Equivalent Future Cost = ₹2,39,655 | Loss in Real Value = 58.27%

Common Use Cases

  • Long-Term Education Cost Planning: Estimate future college tuition fees for school-age children.
  • Salary Real Growth Analysis: Determine if annual salary appraisals beat consumer price index increases.
  • Real Return Calculation: Calculate true purchasing power growth after subtracting inflation from investment yields.
