5 steps
- Rate per period i = 5% / (100 x 1) = 0.05.
- Number of periods N = 1 x 10 = 10.
- Growth factor (1 + i)^N = 1.6288946268; discount factor 1/(1+i)^N = 0.6139132535.
- No level payments, so the single-sum form FV = PV (1 + i)^N applies.
- Present value 10000 grows to future value 16288.95; interest = FV - PV - payments = 6288.95.
