Built for shopkeepers, vendors, and buyers across India — so no one is ever confused or overcharged again.
RateCalc was born from a simple frustration that millions of Indians face every day at markets, kirana stores, sweet shops, and sabzi mandis.
A customer walks in and asks — “Bhaiya, ₹40 mein kitni barfi milegi?” The shopkeeper either does mental math, reaches for a basic calculator, or guesses. Errors happen. Disputes follow. Trust breaks down.
We built RateCalc to solve this — a free, fast, and simple price calculator designed specifically for how Indian markets work. Not a generic calculator app. A tool built for the exact problems that kirana store owners, vegetable vendors, dairy shops, and sweet shops face every single day.
RateCalc is a free proportional price calculator — also known as a Rule of Three calculator. It instantly answers two questions:
For shopkeepers, RateCalc also includes a My Shop Items feature — save your item prices once and load them instantly with one tap. No retyping rates for every customer.
RateCalc is designed for everyone who buys or sells by weight or volume in Indian markets:
RateCalc is and will always be free. A vegetable vendor at a small mandi and a large kirana store owner both deserve the same tool without paying for it.
At a busy shop, you cannot wait 10 seconds for an answer. RateCalc is designed to give results in under 2 seconds — tap, type one number, done.
All saved items and shop names are stored only on your own phone. We cannot see them, access them, or share them with anyone.
Markets in small towns often have poor connectivity. RateCalc works completely offline after the first visit — no data pack needed.
Indian units (g, kg, L, ml), Indian currency (₹), and Indian market scenarios — RateCalc is designed from the ground up for how Indian markets actually work.
