Inputs first, assumptions alongside the answer
The included calculators use manual inputs. Example prices, balances and rates are hypothetical; they are not live quotes. Each tool explains its formula and exclusions so the result can be checked independently.
Each model answers a different question
- Position Size: risk budget divided by entry-to-stop distance. It assumes an exact stop fill and excludes fees, funding and liquidation rules.
- Signal Calculator: each target is a separate full-position outcome. Returns from mutually exclusive exits are not added together.
- Multi-TP: a position is allocated across targets, with user-entered entry/exit fees and partial-target-then-stop scenarios.
- Funding Fees: user-entered settlement rates and notionals determine payments and receipts for linear perpetual contracts. No future rate is predicted.
- Average Entry: buy-only spot purchases distinguish weighted fill price from cost per net coin after fees. It is not a tax-lot or sales-history calculator.
- Ethereum Gas: gas units and fee inputs determine the execution fee. A maximum budget is not automatically charged; separate L2, blob, bridge or exchange costs are outside the model.
- Signal Formatter: supplied values become message text. Formatting does not verify a trade or endorse a signal provider.
- Spot Profit & Loss: one full purchase and sale of unchanged coin quantity, percentage fees paid in quote currency and additional quote costs. Return uses total cash spent. It excludes derivatives and tax-lot accounting.
- Market Cap & FDV: manual price times circulating or explicitly chosen reference supply. A separate scenario divides assumed market cap by assumed circulation. No price or supply data is fetched or predicted.
- Slippage Thresholds: a selected quantity or inverse-price convention turns an entered quote and tolerance into a token-unit threshold. All modes round down. This is not a route simulation, recommended tolerance or transaction builder.
- APR/APY: a constant non-negative rate and equal compounding periods determine an equivalent annual rate and optional one-year token balance. Full same-asset reinvestment is assumed; price changes, costs and penalties are excluded.
- Futures P&L: one full linear-contract exit with manual fees, net funding and other costs. Coin quantity is entered or derived from margin and leverage. Return uses entry notional divided by leverage, not an exchange’s margin engine. Inverse contracts and liquidation are excluded.
- Mining Electricity: measured watts, identical miner count, hours and tariff determine energy costs. Optional hashrate gives running efficiency; optional manually entered fleet revenue gives an operating comparison, not a revenue forecast or hardware ROI.
- Stablecoin Transfer Fees: manual percentage, fixed-token, separate network and recipient costs reconcile sender debit with recipient amount. Entered withdrawal minimums determine comparison eligibility. The worksheet does not fetch fees, verify support or assume a one-unit peg.
- Impermanent Loss: two manually entered price pairs model a full-range 50/50 constant-product liquidity position against holding the starting tokens. Entered fees, incentives and costs are separate cash flows. Concentrated ranges and other pool curves are excluded.
Precision and display
Funding, average-entry accumulation, spot cash flows, supply-scenario products, slippage token units and Ethereum wei arithmetic use decimal/integer techniques to reduce binary-rounding errors. Futures and mining worksheets retain rational intermediate calculations before converting bounded results for approximate display. Stablecoin route and full-range liquidity calculations use bounded floating-point arithmetic and may display rounded values. APR/APY uses floating-point logarithm and exponential functions; tiny non-zero rates are displayed in scientific notation. Very small non-zero spot/supply, futures/mining and final-batch results also use scientific notation. The position and target tools use bounded numeric inputs and tested arithmetic; these tools are not arbitrary-precision financial ledgers.
Checks before a release
Development checks include worked examples, malformed inputs, range limits, long/short direction, fee handling and stale-result behaviour. These checks do not certify every browser, exchange rule or real-world execution. Unit tests and an actual hosting test are different kinds of evidence.
