Inflation-Adjusted Rate of Return Calculator

Understanding the true performance of your investments requires looking beyond the nominal return and considering the impact of inflation. The inflation-adjusted rate of return, also known as the real rate of return, tells you how much your purchasing power has actually increased after accounting for the erosion of value caused by rising prices.

Inflation reduces the value of money over time. For example, if your investment earns a nominal return of 5% in a year, but inflation during that same year was 3%, your real rate of return is only 2%. This means your investment grew enough to buy only 2% more goods and services than you could have at the beginning of the year.

This calculator will help you determine your inflation-adjusted rate of return. Simply input your investment's nominal return and the rate of inflation, and the calculator will provide the real rate of return.





function calculateRealReturn() { var nominalReturnInput = document.getElementById("nominalReturn"); var inflationRateInput = document.getElementById("inflationRate"); var resultDiv = document.getElementById("result"); var nominalReturn = parseFloat(nominalReturnInput.value); var inflationRate = parseFloat(inflationRateInput.value); if (isNaN(nominalReturn) || isNaN(inflationRate)) { resultDiv.innerHTML = "Please enter valid numbers for both inputs."; return; } // Formula for real rate of return: ((1 + nominal return) / (1 + inflation rate)) – 1 var realReturn = ((1 + (nominalReturn / 100)) / (1 + (inflationRate / 100))) – 1; // Convert to percentage var realReturnPercentage = realReturn * 100; resultDiv.innerHTML = "

Real Rate of Return:

" + realReturnPercentage.toFixed(2) + "%"; }
