Boba Tea Shop Profit Calculator — Break-Even and Ramp-Up

How many cups a day does your boba shop need?

Enter your price, cup costs, staff, rent and loan. You get profit per cup, monthly profit, break-even cups a day with the loan, the drink price that reaches your target margin, sensitivity to volume and ingredient costs, and a sixty-month ramp-up with the cash reserve it burns, before you sign the lease.

What this counts, and what it leaves out

Revenue per cup = drink price + topping attach rate × topping price. Card, delivery commission and royalty are percentages of that revenue.
Ingredients per cup = (drink + attach rate × topping + packaging) × (1 + waste).
Fixed costs = paid staff hours × open days × wage × (1 + payroll taxes) + rent + utilities + other + your pay. The loan is the startup cost less your cash in, amortised at the rate and term you enter.
Ramp: volume climbs in a straight line from your month-one level to full over the months you enter. Cumulative cash starts at minus your cash in; payback is the first month it is zero or above.
Not modelled: seasonality, a second location, equipment replacement, income and sales tax, lease terms beyond monthly rent, permits, inventory build-up, tips, and any price, yield or market figure. Every number comes from you.

Common questions

How much does it cost to open a boba tea shop?

Build-out, equipment, deposits and opening inventory commonly run into six figures for a store-front shop, far less for a kiosk or cart. Enter your own total in the startup cost field and your cash in; the rest is treated as a loan and its payment is part of break-even.

How many cups a day does a boba shop need to break even?

Divide monthly fixed costs (staff, rent, utilities, your pay, and the loan payment) by what each cup contributes after ingredients, packaging, waste, card fees, delivery commission and any royalty. The report gives the figure both with and without the loan.

How much do delivery apps cost a bubble tea shop?

The commission comes off the sales that go through the app, so a 25% commission on 20% of sales is a 5% cost on everything. The tool charges it only on the delivery share you enter.

What price do I need for a target profit margin?

The report solves for the drink price that reaches your target net margin at your entered volume, after every cost and the loan payment, and says so plainly when no price can reach it.

How much extra cash do I need while sales ramp up?

The ramp table runs sixty months with volume climbing from your month-one level to full. The lowest cumulative cash point, above what you spent at opening, is the working-capital reserve to hold.
