Guesstimate Demonstration: How many UPI transactions happened in India in 2020? 

pls make more videos🙌🏻

This kind of guestimate surely need a lot of intelligence and experience. You are the guestimate goddess 😄

Nice approach!

very nice explanation mam beginners can learn in easy way tosolve it mam.

It was really insightful. Just a question isn't the formula for Avg No. of txn / year need to be multiplied by 4 as the current fml gives txn/quarter?

Hi. This was quite helpful. I am unsure why we have done 4*3, as the total is per week, and there are 52 weeks roughly in a year. Moroever, don't you think a female:male segmentation should be considered somewhere, assuming that UPI/mobile phone users/bank a/c holders and eventually UPI users among females would be lower, especially in the rural areas

I had a different approach altogether. My formula would look like # Transactions = (Total Amount paid through UPI per month) * 12/Average amount per transaction. For the total amount paid through UPI, I would bifurcate the population (household), urban/rural, and tech/internet penetration, post that, I would make a table for the monthly expenditures of the family and the modes of transactions (UPI/Internet Banking, Direct Banking, Cash, etc). For average amount per transaction, a weighted matrix of average cost per transaction across shopping, groceries, etc. Do let me know if there are any considerations missing in the approach.

Could you explain why you did the 50% digital literacy in the sanity check? Also, don't you think we should have considered per household (averaging 4 people in a house in urban) and perhaps 5 or 6 people in a household in rural India, simply because everybody is not doing a UPI transaction for staples in a household, it's usually just one person.
