As a Young Married Couple,We will be Shifting to Noida or Eastern Delhi. So How Much Overall Monthly Expense can we Expect when living-1 BHK

35k tk lagega approx It depends on what accommodation you opt for, area wise kafi variation hai

Biggest portion of expenses will be your rent.(~15K) The rest of the expenses will be the same as what you're incurring currently.

Don't move out of Delhi if you opt for noida you will definitely miss Delhi

10K rent as of now, 20k food, grocery including outside food also. If you are vegetarian

Please Comment also and Let me know

There are a lot of variables. If you don't order much from outside or spend a lot on movies etc, even 25k is decent (rent excluding). If you add travelling cost using own vehicle / non metro, it is bound to go up.
