zFX calculator
The zFX Calculator helps businesses estimate how much a recipient will receive when a stablecoin payout is settled into local currency through zPayments.
Enter a USDC amount, choose a supported destination currency, and zFX shows the local payout amount using the live zFX rate for that corridor.
Use it to check payout amounts before speaking with the zPayments team, sharing a quote internally, or embedding a simple payout calculator on your own website.

What the rate means
The zFX rate is the effective payout rate shown for the selected corridor.
It is designed to show the recipient-side amount more clearly than a standard mid-market FX calculator. Standard FX converters usually show reference rates, while the final payout amount can differ because of provider margins, route costs, or settlement fees.
zFX is built to show the payout rate more directly so businesses can understand what the recipient should receive before initiating the payout.
Important note on live rates
Rates move with market and corridor liquidity conditions.
The calculator shows the live rate available at the time of viewing. Final payout details should be confirmed with the zPayments team before execution, especially for larger transfers, delayed settlement, or corridor-specific requirements.
Supported corridors
The calculator currently supports USDC-based payout calculations for selected destination currencies.
The Global FX Rates board may also show additional base currency views and corridor data as new routes are added.
