Health, Fitness and Food are non negotiables for me.
A healthy homemade high protein diet will cost you atleast 15k per month (considering a maid will charge 5k per month to cook, and raw materials will cost 10k)
Fitness will cost you 4k per month on an average (investing in gym membership, shoes, other equipments)
Apart from this, the mandatory expenses include Rent (let’s say 20k), travel (probably 5k per month)
This itself has come to 45k per month. Round it off to 50k. Then there are other expenses like shopping, going out with friends - these depend on every individual.
Then there’s money that you need to set aside for investments and insurance.
So imo a minimum of 1L is needed to live a comfortable life if you’re a bachelor. It goes up if there’s a family dependent on you.
