Time Value Money Formula

The formula of time value of money considers as present value or future value, and it can be calculated as: 

PV = FV/(1+r)^n

FV = PV * (1+r)^n

Where,

PV = Present Value

FV = Future Value

r = annual rate of return

n = number of years 

Note-1: The value of PV or FV is affected by rate of return (r), type of rate, holding time period and compounding approach. The compounding approach could be annually, semi-annually, quarterly, monthly, weekly, daily and continuously.

Note-2: Do the following adjustment in annual rate of return and time period if anything mentions in compounding approach:

  • Compounding- Annually = r/1 and n*1
  • Compounding- Semi-annually = r/2 and n*2 
  • Compounding- Quarterly = r/4 and n*4 
  • Compounding- Monthly = r/12 and n*12 
  • Compounding- Weekly = r/52 and n*52 
  • Compounding- Daily = r/365 and n*365 
  • Compounding Continuously =  e^rn

Note-3:  No changes if compounding is annually and you can use 360 total number of days in a year. It depends on practices.

Note-4: The type of rate also affects the PV and FV. Basically there are two types of rate used in practice. One in Reducing Rate and another is Flat Rate. Under flat rate,interest is calculated on the initial principal amount throughout the loan tenure. While under reducing rate, interest is calculated on the remaining principal amount at any time.
