How much is the GP fee for Grab / Lineman / FoodPanda in Thailand?

Most delivery platforms in Thailand charge a GP commission of 25 to 32 percent including VAT. Grab Food is typically around 30 percent, Lineman 28 percent, FoodPanda 32 percent, Robinhood 25 percent, and Shopee Food 30 percent. The platform selector in this calculator lets you compare side by side.

What is yield loss and why does it matter for restaurant cost calculation?

Yield loss is the percentage of weight lost during cleaning, trimming, and cooking. Pork and chicken typically lose 25 to 35 percent, yielding 65 to 75 percent. Fresh vegetables lose 10 to 20 percent. If you ignore yield loss, your real cost is significantly higher than the Makro receipt price suggests, and you will underprice your menu.

What is a healthy net margin for a Thai restaurant?

For most Thai restaurants, a sustainable net margin sits between 8 and 15 percent after rent, staff, and overhead. Per-dish food margin should be 60 to 70 percent. For delivery menus, you must price in the GP fee or your true margin drops below 5 percent.

How much should I budget for delivery packaging per dish in Bangkok?

In Bangkok in 2026, a standard foam box plus carry bag and utensils totals roughly 4 to 7 baht per dish. Eco kraft boxes cost 8 to 12 baht. The PeeYai calculator defaults to 5 baht, the midpoint for a standard Makro foam box set.

How much higher should delivery prices be compared to dine-in prices?

To preserve the same net margin as dine-in, delivery menu prices need to be approximately 45 to 50 percent higher to offset the 32 percent GP fee plus packaging and added overhead. Restaurants pricing delivery the same as dine-in are usually losing money without realizing it.

Is the platform GP fee tax-deductible in Thailand?

Yes. GP fees paid to Grab, Lineman, or FoodPanda are deductible operating expenses for both corporate and personal income tax in Thailand, provided your business is properly registered. Keep monthly tax invoices from each platform or use their built-in revenue and expense reports.

Why use this calculator instead of an Excel sheet?

Excel works, but this calculator pre-fills Thai market defaults (25 to 32 percent GP, 70 or 85 percent yield, 5 baht packaging) from real data. No guessing, no spreadsheet — open it on your phone and validate any new menu margin from the kitchen counter. Compare mode also lets you benchmark up to 5 dishes side by side.

Does this calculator work for buffet or shabu restaurants?

Yes, but you need to use average cost per head instead of per dish. Sum all ingredient cost per session divided by guest count (typically 70 to 80 percent of prepped weight gets eaten), then enter as Raw Cost. Selling Price is the buffet price per person.

Can I use this for drinks or coffee cost calculation?

Yes. For drinks, select Vegetable yield 85 percent since real loss is minimal. Add cup, lid, and straw cost into Raw Cost. A plastic cup set in Thailand runs 3 to 6 baht.

Why does this calculator default meat yield to 70 percent?

Seventy percent is a safe average for pork, chicken, and beef after deboning, trimming, and cooking. In practice, chicken breast can hit 90 percent yield with no bone, while fried pork belly may drop to 55 percent.
