NPER(rate, pmt, pv [,fv] [,type])

 
 Returns the number of compounding periods of an annuity.

 rateThe fixed interest rate per period.
 pmtThe payment made each period.
 pvThe present value.
 fv(Optional) The future value (or cash balance) after all the payments.
 type(Optional) The number indicating when the payments are due:
0 = the end of the period (default)
1 = the start of the period

 REMARKS
 
  • This function allows you to calculate the length of time it will take to arrive at a particular value in the future.
     
  • Any cash you pay out is represented by a negative number.
     
  • Any cash you receive (start with or end with) is represented by a positive number.
     
  • The "rate" can be entered with a percentage sign or as a decimal.
     
  • If "fv" is left blank, then 0 is used.
     
  • The "pv" is the present value of
     
  • If "type" = 0, then payments are made in arrears.
     
  • If "type" is left blank, then 0 is used.
     
  • Example 1 & 2 - How many years will it take an investment of £1,500 to grow to £2,000 if the average annual growth rate is 4.3%.
     
  • Example 3 - How many years will it take for me to save £60,000 if my bank account is currently £5,000 and I deposit £750 every month with monthly interest of 0.5%.
     
  • Example 4 - How many months will it take for me to save £60,000 if my bank account is currently £5,000 and I deposit £750 every month with monthly interest of 0.5%.
     
  • Example 5 - This is checking the answer in Example 3.

     EXAMPLES
     
     A
    1=NPER(4.3%,,-1500,2000) = 6.83 years
    2=NPER(4.3%,0,-1500,2000) = 6.83 years
    3=NPER(0.5%,-750,5000,60000) = 74.26 years
    4=NPER(0.5%,-750,5000,60000)*12 = 891.12 months
    5=RATE(74.26,-750,5000,60000) = 0.5%
