Define the path you are comparing
Write down the hypothetical steps: funding, conversion if needed, execution, holding or custody, and withdrawal or transfer. Identify the product and relevant legal entity, and verify which steps actually apply.
A comparison cannot be normalized by brand name alone. One route may stay off-chain inside a service while another includes a network transaction. Do not add a network cost to every internal account movement or assume the same charge for every network.
Separate the cost categories
Coinbase’s public disclosures describe product-dependent charges and note regional scope. That is a reason to inspect the actual terms and preview, not a universal rate for the checklist.
Ethereum documentation describes network execution fees using gas-related concepts. Those fees are a different category from an exchange trading percentage. This article supplies no current gas quote and does not generalize Ethereum’s mechanism to every chain.
| Stage | Questions to verify |
|---|---|
| Funding | Payment method, deposit currency and bank/provider charges |
| Conversion / execution | Rate, spread, maker/taker scope and notional |
| Holding / custody | Any product-specific subscription, custody or financing charge |
| Withdrawal / network | Provider fee, selected network and whether costs overlap |
| Other obligations | Tax/reporting questions requiring separate qualified review |

Put each amount on an explicit basis
A percentage needs a notional and a statement of whether it applies once or more than once. A fixed charge needs a currency and an event, such as one transfer. Charges in a token require a dated conversion assumption before they can be added to USD figures.
Do not combine a quoted all-in price with a separately estimated component that is already included. Record whether the available evidence gives a total or a component; if the boundary is unclear, mark the calculation incomplete.
Use a small invented cost stack
Suppose a fictional $1,000 execution has an assumed 0.2% trading fee, or $2, plus a separate invented $3 transfer charge. Under that deliberately limited scope, the sum is $5, equivalent to 0.5% of the $1,000 reference notional.
This is not a provider quote or a realistic default budget. It does not include a sale, change in asset price, spread or taxes. The fee comparator alone would model the $2 trading component, so its output must not be labeled the full $5 workflow cost.
| Assumed component | Amount |
|---|---|
| $1,000 × 0.2% | $2 |
| Separate flat transfer charge | $3 |
| Limited modeled sum | $5 |
Keep unknowns in the result
An unavailable fee should remain “not verified.” Present a partial subtotal as a partial subtotal, not a complete estimate with the missing values silently set to zero.
Compare eligibility, custody and execution questions alongside cost. This checklist does not establish solvency or recommend a platform. Nor does it suggest more trading or larger deposits to access a lower tier.
Record enough evidence to refresh it
Keep source URL, review date, product, pair, currency, tier and excluded steps with the worksheet. Recheck before relying on a saved result, especially after a provider notice or a network change.
If the task involves an actual legal or tax conclusion, seek appropriately qualified advice for the relevant jurisdiction. A transparent educational inventory helps locate unanswered questions; it does not resolve them automatically.
