Worked example and sanity check

As a worked reference for “Count ROI”, Worked example Investing 50,000 and receiving 65,000: ROI = (65,000 − 50,000) ÷ 50,000 × 100 = 30% .

Interpreting the result

The output is only useful against a reference. The example's (65,000 − 50,000) ÷ 50,000 × 100 = 30% gives that reference: your own result should be explainable against it — larger or smaller for a reason you can name. Treat the result as an estimate for planning; the filing-year rules, thresholds and your full income picture decide the actual liability.
