Buy formula
Gross fiat = crypto amount × entered price. Entered percentage cost = gross fiat × percentage. Total fiat paid = gross fiat + percentage cost + fixed cost. Effective buy price = total fiat paid ÷ crypto amount.
One side, amount and set of quotes
Use quotes for the same asset amount, fiat unit and buy or sell side. Recheck all provider details before acting.
Entered-quote comparison
—
A lower entered buy total or higher entered sell proceeds is only a mathematical observation. This tool cannot test whether a quote remains executable, a merchant is safe, funds will settle, or a payment method is suitable.
Sell formula
Gross fiat = crypto amount × entered price. Net fiat received = gross fiat − percentage cost − fixed cost. Effective sell price = net fiat received ÷ crypto amount.
Quote evidence and freshness
Use the displayed executable price, limits and fees for your exact amount and payment method. Record when each quote was checked. Quotes can change immediately; this worksheet has no live, cached or fallback rate.
Privacy and decision boundary
Calculation and export happen locally. Do not enter account numbers, login details or personal identifiers. This is not financial, investment, legal or safety advice and does not endorse a platform or merchant.
P2P quote comparison questions
Why must every quote have a checked-at time?
P2P ads move quickly. A timestamp documents when you observed a quote but does not guarantee that it is still available.
What costs should I enter?
Enter only costs not already included in the displayed price, such as an explicit percentage charge or fixed transfer cost. Use zero only after confirming none applies.
Why are payment method and limits not calculated?
They are provider-specific eligibility facts, not arithmetic inputs. Confirm minimum, maximum, availability, payment method and merchant terms directly.
