Travel calculators
Exchange rates and trip money tools without an account.
These tools cover the money side of travel: currency conversion with live mid-market rates and an estimated bank spread so you can see the true cost of exchanging cash or paying with a foreign card, a frequent-flyer mile value calculator that converts award redemptions to cents-per-mile and compares against program benchmarks, and a travel cost splitter that handles groups of up to eight travelers across multiple currencies.
The bill splitter handles restaurant and group meal splits with equal, itemized, or custom-weight breakdowns including tax and tip. All calculations run in your browser with no account required. Exchange rate data is fetched on load but calculations themselves are client-side, so you can use the tools in flight mode after the page loads.
