Try this site where you can compare quotes from different companies: WWW.ANNUITY-HELP.US URGENT - Annuity with 2 different interest rates for different years? A 15-year annuity pays $1,500 per month, and payments are made at the end of each month. The interest rate is 11 percent compounded monthly for the first seven years, and 7 percent compounded monthly thereafter. What is the present value of the annuity? I got PV at 0 years = $87,604.36 and PV at 7 years = $110,021.35. I'm not sure if I just add these numbers together or how I get the final answer please explain
