How this calculator works
This tool runs entirely in your browser. None of the values you enter are sent to our server, stored, or shared with any third party. The calculation logic is open for inspection in the page source — we believe methodology should be transparent.
The data used (provider fees, exchange-rate margins, visa thresholds, tax brackets, cost-of-living indices, etc.) is drawn from official sources, provider websites, and our own ongoing research. We update the data quarterly and note the last review date in the page metadata. Rules change frequently in our coverage areas — always confirm critical decisions with the relevant embassy, tax authority, or financial regulator before acting.
This calculator provides estimates for informational purposes only. It is not financial, tax, legal, or immigration advice. For decisions with significant financial or legal consequences, consult a qualified professional who can review your specific circumstances. See our full disclaimer.
