profit percentage (profit divided by cost) = $50/$100 = 50% profit percentage. R.O.I. (return on investment) multiple = $50/$100 (profit divided by cost). If your revenue is the same as your cost, that doesn't equate to 100% return on investment, it equates to 0%. The result above or below 100% can be calculated as the percentage of return on investment.
1Cost for Electricity quoted at $05.794 per kWh (for first 600 kWh), then at $06.9 per kWh for up to 700 additional kWh, and cost of $08.254 per kWh for all electricity over 1300 kWh, quoted by Avista Utilities.

Power costs vary, but $0.10 per kilowatt-hour (kWh) is a reasonable average across the U.S. The pumps assumed here are crank-drive pumps. If you are using an intensifier pump, add about 20 percent to the power costs to cover the additional cost attributed to the lower pumping efficiency.ower costs vary, but $0.10 per kilowatt-hour (kWh) is a reasonable average across the U.S. The pumps assumed here are crank-drive pumps.
