Investment Inflation Calculator

How it's calculated

Nominal FV = S × (1 + i)^m + C × ((1 + i)^m − 1) ÷ i, i = (1 + r)^(1/12) − 1
Real value = nominal ÷ (1 + inflation)^years
Real return = (1 + r) ÷ (1 + inflation) − 1

A balance that grows in money terms can buy less if inflation outruns the return. The real value shows the future balance in today's buying power, and the real return is the growth that is left after inflation (the Fisher relation, not simply return minus inflation).
