What is a Devex Calculator and How It Works

Devex, short for development exchange, is a unit of account used in international development and humanitarian aid to standardize the reporting and comparison of donor contributions. A devex calculator converts national currencies into devex using daily exchange rates maintained by the OECD Development Assistance Committee.

What is a Devex Calculator?

A devex calculator is a financial tool that converts amounts in various DAC currencies into devex equivalents. It ensures that aid contributions from different donors can be compared on a common basis, regardless of the original currency.

Key Inputs
