Common errors

Revenue and cost are entered in reverse order.

Fix: Enter return or revenue first and cost second.

The user expects break-even analysis rather than ROI percentage.

Fix: Remember that this tool shows return relative to cost, not all financial planning metrics.

Cost is zero and the ROI calculation becomes invalid.

Fix: Use a valid non-zero cost value for standard ROI calculations.
