Using the Currency Calculator
For example, when converting dollars into rupees, the rate field should contain rupees per dollar. Reverse the rate if you reverse the direction. Use the provider’s actual offered rate when estimating a transfer rather than a market headline alone.

Method and assumptions
Amount × exchange rate × (1 − fee). Rates are user supplied, not live market quotes.
Identify the base before applying a rate
A percentage always applies to a particular base amount. Write down which amount is being multiplied and whether the rate adds to it, subtracts from it or converts it to another unit. Applying the same percentage to a different base produces a different result. For a real transaction, use the rate and rounding convention that actually apply.
Common question
Can I include a fixed transfer charge?
The fee field is a percentage deduction. For a fixed charge, subtract it from the appropriate currency amount separately, taking care to follow the provider’s order of operations.
