Zar + Arth
Zar is gold in Persian and Urdu, the word inside zardozi, the gold embroidery of Lucknow and Hyderabad. Arth is Sanskrit: wealth, and also meaning. It’s the root of Arthashastra and of arthvyavastha, the economy.
Zarth puts them together: money that means something you understand.
Why it exists
Most money decisions in India happen with half the picture. An offer letter shows CTC, not take-home. A loan shows the EMI, not the ₹50 lakh of interest behind it. A SIP app shows returns, but not what they’ll buy after twenty years of inflation. The maths isn’t hard. It’s just rarely shown.
Zarth shows it. Every tool gives you the number, a picture of where it comes from, and a plain sentence about what it means for you.
