How it's calculated
Monthly rate i = (1 + r)^(1/12) − 1. Balance = Initial × (1 + i)^m + Contribution × ((1 + i)^m − 1) / i, with contributions at the end of each month. Real balance = Balance / (1 + inflation)^years.
The real gain is what's left after subtracting what you put in and the loss of purchasing power. If it comes out negative, your money earns less than inflation.
