Use the compound interest formula to find the compound amount on a $12,000 investment at 5% compounded quarterly for 4 years.

Total = Principal * [1 + (rate/n) ]^n*years

Where "n" is the compounding periods per year

Total = 12,000 * (1 + (.05/4)) ^ (4*4)

Total = 12,000 * (1.0125) ^ (16)

Total = 12,000 * 1.2198895477

Total = 14,638.67
