PV, FV and IRR
Future and present value, savings with regular deposits, NPV and internal rate of return.
What to find:
Numbers separated by spaces, semicolons or new lines; fractions as 1/6, decimals as 2.5.
Money today is worth more than money next year, because it can be invested. This is the time value of money.
FV = PV · (1 + r)t
NPV = Σ CFk / (1 + r)k
IRR is the rate that makes NPV zero. If flows change sign several times, IRR may not be unique; the calculator shows the lowest one found.
