Hi Zeng Sheng,

Thanks for the tips on

团购. My wife actually does use grocery 团购 once a while. I don’t think it saves us a lot.

Today I want to explain why nutrition accounts for about 20% of monthly burn rate.

( In Consumer Price Index, mortgage payment and investment amounts are excluded. So the total monthly burn rate in CPI calculation could be lower than the total monthly outlay in your calculation. )

I think my nutrition expenses is $800-1000 a month including

• about $100/M restaurant dining. Every time I bring my son out, he would pick some Japanese restaurant. Typically $20-$30 each visit.
• supermarket + wet market — perhaps $150 a week. My wife’s Supermarket spend adds up to around $400-500. I spend at least $10 each trip, more than 6 times a month.
• desserts and drinks (excluding purchases in restaurants + supermarkets). Sometimes $10 in a day. For example, after every exercise trip with my kids, we would reward ourselves with these sweet indulgences.
