About Antique Appreciation Calculator

Nominal value compounds at the appreciation rate, and dividing by compounded inflation restates that value in the purchasing power of the year you bought it. An antique appreciating at 4.5% while inflation runs at 2.5% is really gaining under 2% a year, and that gap is what decides whether it was an investment.

Formulas

Nominal value

value = purchase price x (1 + appreciation rate) ^ years

Real value

real = nominal value / (1 + inflation) ^ years
