Terbit is a technology company built by world-class supply chain consultants. We turn decades of expertise into free, precision tools for everyone.
The Terbit team is a group of professional supply chain management consultants from top-tier global consulting firms. With a combined experience of over 30 years, we have advised multinational corporations and SMEs across Asia, the Middle East, and Europe on procurement strategy, strategic sourcing, and cost reduction.
We built Terbit because we saw the same problem everywhere: businesses and individuals spending hours on calculations that should take seconds. Our answer was simple — take our consulting expertise and turn it into free, accessible tools.
Everything we build serves one of three core missions — tools, procurement, and travel.
We build intuitive, accurate digital tools that replace complex spreadsheets and manual calculations. From financial planning to health metrics, our 26+ free calculators deliver instant, reliable answers.
Our Total Landed Cost Calculator is built on 30+ years of real-world procurement expertise. We help SMEs understand the true cost of sourcing — duties, freight, insurance, and all hidden charges — before they commit.
We help frequent travellers and business professionals get more from their loyalty programmes. Our Airline Mileage Calculator covers 48+ airlines across 8 regions, helping you plan smarter and travel further.
Every calculator is built on verified formulas and real-world data. We never guess.
Our mission is simple — replace hours of manual work with seconds of clarity.
Decades of consulting knowledge, distilled into tools anyone can use for free.
We understand the challenges small and mid-size businesses face. Our tools are designed for them.
We show estimates clearly labelled as estimates, with full transparency on assumptions.
Every tool is tested for simplicity. If it takes more than 30 seconds to understand, we redesign it.
