Free Investing & Crypto Calculators
Returns, compounding, position sizing and risk — the arithmetic that turns a hunch into a number you can argue with.
30 free tools · no signupReturn figures need a time base
A 60% gain means nothing until you know whether it took eight months or eight years. CAGR and annualised-return tools normalise for time, which is the only way two investments become comparable. The same discipline applies to fees: an expense ratio that sounds negligible compounds into a large number over a long horizon, and the fee calculator shows that total.
Position sizing is risk management
How much to buy is a risk decision before it is a conviction decision. The position-size and risk-reward tools work backwards from the loss you are willing to accept, which produces a very different answer from working forwards from how much you like the idea.
Estimates, not recommendations
None of these tools evaluates whether an investment is good. They calculate what a set of assumptions implies. Past returns do not predict future ones, and every page in this set carries a plain statement that its output is a planning estimate rather than investment advice.
