# Calculate Cross-Border Costs

Cross-border payments involve more than just the face value -- exchange rates, timing, and rate spreads all affect the actual cost. A company paying an overseas invoice needs to know the exact local currency equivalent today. A developer sending remittances wants to know how much arrives after conversion. Understanding the true cost of international transfers requires real-time rate data.

The convert skill calculates precise amounts at current market rates, while latest_rates provides the baseline for comparing against the rates offered by banks and payment providers. The difference between the market rate and the offered rate is the hidden cost of the transfer.

This serves businesses making international payments, individuals sending remittances, finance teams budgeting for overseas costs, and procurement teams comparing international suppliers. By knowing the market rate, you can evaluate whether your bank or payment provider is giving you a fair deal and calculate the true landed cost of any international transaction.
