Calculator pack
Investment and Crypto Risk Calculator Pack
A calculator path for comparing returns, growth rates, average cost, fees and position risk without pretending estimates are guarantees.
Who this pack is for
Use this pack to make investment arithmetic more honest before making a decision. It does not give investment advice, price forecasts or recommendations. It helps separate return, risk, time and fees.
The crypto tools are included because they are popular, but they need careful framing. A calculator can show position size or profit math; it cannot tell you whether a trade is sensible.
Start with these tools
Start with return math, then check time, fees, average cost and risk per position.
The best order to use them
- Use ROI with fees included. Save the no-fee version and the fee-included version if you want to see the difference.
- Use CAGR when the holding period is more than one year, because the same gain can mean different annual growth over different time spans.
- Use Rule of 72 only as a shortcut for comparing rates. Do not treat it as a forecast.
- Use average cost before profit calculations so the entry cost is not guessed.
- Use crypto position size to cap risk per trade before looking at possible profit.
Save and compare your scenarios
Each calculator now has a local saved-results panel. Run the first scenario, press Save result, change one input, then save again. The comparison table is stored only in the browser you are using, so it does not require an account and it is not sent to Figure It Quick.
The useful habit is to name the difference in plain language: cheaper plan, realistic plan, stretch plan, worst case, or next month. A saved result without the reason behind it is easy to misread later.
Worked path
A 20% gain over one year and a 20% gain over five years are not the same growth story. CAGR makes the time period visible. ROI tells the total return; CAGR tells the annualized path between two points.
For trading, position size should come before excitement about upside. If account risk is 1% and the stop is far from entry, the calculator will show fewer units. That is the point: risk distance controls size.
How to judge the comparison
Investment comparisons need time labels and risk labels. A return that looks strong over one month may not mean much over a full cycle. A return that looks moderate over ten years may be excellent after fees and volatility are considered. Save the time period with every result.
For crypto and trading tools, the most useful saved comparison is often the uncomfortable one: higher fees, wider stop, lower sell price or smaller position. If the decision collapses under conservative inputs, the calculator has revealed dependence on optimism.
Return tools and position-size tools answer different questions. ROI and CAGR describe what happened or what a scenario assumes. Position sizing asks how much account value is at risk if the trade is wrong. Keep those concepts separate.
When to stop calculating
Stop calculating when you know the maximum loss you are willing to accept and the assumptions required for the optimistic case. If either answer is unclear, the next action is more research or no action, not a larger position.
Mistakes this pack helps prevent
- Ignoring fees, spread, tax or funding costs when calculating return.
- Comparing prices without considering supply, average cost or time period.
- Using Rule of 72 as if returns are stable or guaranteed.
- Choosing crypto position size from desired profit instead of defined risk.
What to do after the numbers
Save a conservative scenario first. Then save a more optimistic scenario. If the decision only works under the optimistic version, the calculator has found a risk worth thinking about before acting.
