Currency & Holiday Calculator

TripCalc — the calculator built for travel.

Your travel companion for money and more. Live currency conversion across 161 currencies, card fee profiles so you always know what you'll actually pay, plus a tip calculator, fuel converter, distance and temperature tools, and an international clothing and shoe size guide — everything you need when you're away from home.

No ads. No account. No tracking.

CURRENCY CONVERSION

Rates are fetched automatically from open.er-api.com, covering 161 currencies worldwide. Rates refresh every 24 hours and are cached so the app keeps working offline. Set a custom rate if you've already locked in your exchange rate from a bank or travel money provider.

CARD PROFILES

Create named profiles for your payment cards, each with its own foreign transaction fee percentage and optional minimum charge (e.g. 2.75% or minimum £3). The app applies the correct fee automatically and shows the true cost of every transaction. Add per-card exchange rate overrides for currencies where your card offers a fixed or non-live rate.

TIP & BILL SPLITTING

Enter the bill, choose your tip percentage (or set a custom one), and split it however many ways you need. One tap sends the total straight to the currency converter — so you always know what you're paying in your home currency.

UNIT CONVERSIONS

CLOTHING & SHOE SIZE CONVERTER

FULL CALCULATOR

All the standard operations — add, subtract, multiply, divide — plus brackets for complex expressions and a percentage key. A scrollable history of recent conversions lets you tap any entry to restore it instantly, with optional notes to label what each calculation was for.
