Core formulas
- Estimated holdings
- Total investment ÷ average purchase price
- Target portfolio value
- Estimated holdings × target price
- Estimated profit or loss
- Target portfolio value − total investment
- Estimated return
- ((Target price ÷ average purchase price) − 1) × 100
- Hypothetical market cap
- Target price × current circulating supply
- Hypothetical FDV
- Target price × current total supply
Calculations use arbitrary-precision decimal arithmetic. Trading fees, tax, slippage and later exchange-rate changes are not included.
Estimated market-cap rank
The selected coin is removed from the comparison set. We then count coins whose current market cap is strictly greater than the hypothetical market cap and add one. Equal values do not rank ahead.
The default comparison depth is the current top 250. If the hypothetical market cap is below the final value in that snapshot, the result is shown as estimated outside the top 250 rather than an invented exact rank.
Supply and FDV
Provider-reported circulating supply takes priority. If it is missing but the same snapshot has price and market cap, supply is estimated as market cap divided by price and labelled as estimated. Manual supply is offered only when neither method is available.
FDV is hidden when total supply is unavailable. Portfolio value and profit or loss can still be calculated without supply, but hypothetical market cap and rank cannot.
Snapshot and limitations
Price, market cap, supply and the ranking set are fixed to the snapshot used when the form is submitted. Data older than 30 minutes carries a delay warning; rank is hidden after 24 hours.
This is a mathematical comparison that assumes circulating supply and every other coin’s market cap remain unchanged. It does not forecast a future price or rank.
