Worked out from Return on investment: ROI = (final value - cost) / cost and 3 other sources.
Single-period, undiscounted arithmetic on the figures you entered. Fees, taxes, inflation, risk, leverage and the timing of any intermediate cash flows are not modelled, and no market data is looked up.

How this is worked out

2 steps
  1. Net gain = 1200 - 1000 = 200
  2. ROI = 100 x 200 / 1000 = 20%
