How this is worked out

6 steps
  1. Payment on 100000 at 6% over 360 periods = 599.55
  2. Amount financed = 100000 - 0 = 100000 (12 CFR 1026.18(b))
  3. Finance charge = 360 x 599.55 - 100000 = 115838.19
  4. Unit-period rate solving 100000 = payment x annuity factor is 0.5% per period
  5. APR = 0.5% x 12 periods = 6%
  6. Finance charge per $100 financed = 100 x 115838.19 / 100000 = 115.8382
