# Estimate new conversion rule by account

> Uses the authorized account's country to estimate a conversion rule before you create it.

Returns the indicative amounts, rate, and fees for a hypothetical deposit to a conversion rule. An estimate does not lock a price, reserve funds, or create a conversion rule.

Provide `amount` as the gross deposit amount in the source asset. Specify bank rails and crypto networks without bank account details or crypto addresses. To create the conversion rule, call [Create conversion rule](./create-conversion-rule).
