This inbox is not a black hole. Notes sent to CoinMetra are read by the team that maintains the tools, so the more context your message carries, the quicker it can be dealt with.

The tool behind this page is CoinMetra, a crypto profit and DCA calculator. Questions usually involve estimating tax before selling a position or a number that came out differently than expected, and both are useful to hear about.

Include this

• A link to the page, or the name of the calculator you used.
• What you entered — for CoinMetra that is usually the buy and sell prices, amounts and fee percentages you enter — rounded is fine, since we only need to repeat the arithmetic.
• The output you received against the output you expected.
• Device and browser, for anything that looked wrong on screen.

If your question is about checking the real return after exchange fees, say so in the first line — it helps us find the right answer for CoinMetra faster.

Reporting a wrong result

For a personal-finance tool, accuracy is the whole point. Because the CoinMetra tool works the way described on its own page — it averages each buy by the amount invested rather than a simple price mean, deducts the fee from every trade, and applies the selected country's capital gains rules to the realised gain — a wrong answer almost always traces back to one assumption, an input that does not fit the model, or a rounding edge case. If you think you have found one, tell us the value you expected and which tool you used, and we will check it against the method.
