document.write( "Question 205252: Carolyn Ellis is setting up an annuity for her retirement. She can set aside $2000 at the end of each year for the next 20 years and it will earn 6% annual interest. What lump sum will she need to set aside today at 6% annual interest to have the same retirement fund available 20 years from now? How much more will Carolyn need to invest in periodic payments than she will if she makes a lump sum payment if she intends to accumulate the same retirement balance? \n" ); document.write( "

FV=Pmt((1+r)^n-1/r)
\n" ); document.write( "FV=2000((1+.06)^20-1/.06)
\n" ); document.write( "FV=$73566.67
\n" ); document.write( "--------------------
\n" ); document.write( "P=FV/(1+r)n
\n" ); document.write( "P=73566.67/(1+.06)^20
\n" ); document.write( "P=$22940.00
\n" ); document.write( "---------------------
\n" ); document.write( "40000-22940=$17060.00 more with payments.
