Every host carries the same two fears: running out of food in front of guests, and paying for a mountain of leftovers. Both come from guessing quantities. After 5,000+ events, here is the actual maths we use — so you can sanity-check any caterer's proposal, including ours.

Start with the real number: how many will actually eat?

Invited guests ≠ eating guests. Bangalore reality, function by function:

Weddings: 85–90% of confirmed invitees typically eat at the main meal — but spread across sittings, not at once.
Receptions: attendance peaks between 7:30–9:00 PM; plan the buffet's fastest flow there.
House functions: add 10% — neighbours and last-minute relatives always come.
Office events: subtract 10–15% from the RSVP list; workday attrition is universal.

Per-guest quantities for a South Indian meal

Standard full-meal portions (cooked weight)

Two adjustments matter: breakfast functions run lighter (2 tiffin items + one sweet + coffee covers 95% of guests), and evening receptions with starters reduce main-course consumption by roughly 20% — if the chaat counter is good, dinner plates shrink.

The buffer rule

Professionals don't cook to the exact count. The industry-standard buffer is 5–10% above the confirmed headcount, weighted toward rice, sambar and curd — the items guests take seconds of. What you should never do is inflate the headcount itself "to be safe": you'll pay per plate for the inflation, while a buffer is built into how a good caterer cooks.

The seconds pattern: at a traditional meal, guests take seconds of exactly three things — rice, sambar and payasam. A caterer who buffers those three and cooks the rest to count serves everyone AND leaves you minimal leftovers. That's the whole trick.

Live counters change the maths

A live dosa or chaat counter is self-regulating — made to order means zero waste — but it shifts consumption: expect guests to eat 1.5–2 dosas each and correspondingly less from the buffet. Tell your caterer the full format so the buffet isn't sized as if the counter didn't exist.

What this means for your budget

Quantity planning and per-plate pricing are two halves of the same calculation: an honest headcount with a professional buffer beats an inflated count every time, usually by 10–15% of the total bill. Fix the count two weeks before the event — that's the number your final bill should be computed on, and with us it is. Get a quote with your real numbers.
