An annual rate of inflation can have a significant impact over time.
Parameters:
(1) annual inflation rate in percent
(2) number of years at that inflation rate
monthly inflation rate =
= 100% * ((((100 + (inflation))/100)^(1/12))-1)
Hyperinflation is defined as a monthly inflation rate >= 50%. This requires an annual inflation rate of 12,900 percent.
price doubling time =
= LN(2) / LN((100+ (inflation))/100)
inflation rate required to double price in x years =
= 100 * (EXP(LN(2) / (x years)) - 1)
price in x years =
= (current price) * (((100 + (inflation)) / 100)^x)
