冲牙器经销商利润怎么算：单台毛利、销售成本与保本点

Before placing a first order, the most practical question is how much money each unit actually leaves you. Water flosser dealer profit is what remains after platform fees, shipping, advertising and returns, not the discount figure itself. This article uses a hypothetical example so you can plug in your own numbers. Sign-up steps and tier benefits are on the dealer policy page and in the article on the wholesale ordering process.

Where does water flosser dealer profit start?

At Inmax, discounts are calculated on the listed retail price: 15% (Starter), 22% (Dealer), 28% (Distributor) and 35% (Regional Exclusive), based on committed quarterly volume across the whole catalogue. So:

• Unit cost = listed retail price × (1 − discount rate).
• Gross margin per unit = retail price − unit cost, which equals the discount as long as you sell at the listed price.

Gross margin is not money in your pocket yet: every cost of getting the unit to the customer still has to come out.

Four steps to calculate profit per unit

Repeat these four steps whenever you receive a tier price list or open a new sales channel:

1. Choose a discount tier that matches the volume you can realistically sell each quarter, not the volume you hope for.
2. Work out the unit cost with the formula above for every model you plan to stock.
3. Add the selling costs per order: platform fees, shipping, packaging, advertising and a returns allowance.
4. Calculate profit and break-even: subtract selling costs from gross margin, then compare with monthly fixed costs.

Hypothetical example: gross margin per unit at each tier

Assume one unit has a listed retail price of VND 1,000,000. This is an illustrative price, not an actual Inmax price; real prices are sent privately for each tier.

• Starter (15%): unit cost VND 850,000, gross margin VND 150,000.
• Dealer (22%): unit cost VND 780,000, gross margin VND 220,000.
• Distributor (28%): unit cost VND 720,000, gross margin VND 280,000.
• Regional Exclusive (35%): unit cost VND 650,000, gross margin VND 350,000.

The example excludes tax; what you owe depends on your business structure, so check with your accountant or tax office.

Which selling costs need to come out?

Assume you sell through a Facebook page and pay for delivery yourself. These figures are also assumptions; replace them with your real numbers:

• Shipping: VND 30,000 per order.
• Packaging: VND 10,000 per order.
• Advertising: VND 60,000 per order, meaning total ad spend divided by orders closed.
• Returns allowance: if 5% of orders come back and each return costs about VND 200,000 (two-way shipping, ad spend already used, damaged box), set aside 0.05 × 200,000 = VND 10,000 per order.

That totals VND 110,000 per order. Profit before tax: VND 40,000 at Starter, VND 110,000 at Dealer, VND 170,000 at Distributor, VND 240,000 at Regional Exclusive.

Marketplace fees are best kept as a variable, p% of the selling price, because each platform and category charges differently and rates change over time. In May 2026, Vietnam's National Competition Commission reviewed sellers' complaints about new and adjusted marketplace fees (VietTimes, Vietnamese news source). On a VND 1,000,000 unit, every 1% in fees takes VND 10,000; at the Starter tier, fees of 4% wipe out the profit. Check the current fee schedule in each seller centre before listing; for running a store, see selling water flossers on marketplaces.

Break-even point and capital turnover

According to the U.S. Small Business Administration (SBA), break-even in units equals fixed costs divided by the gap between price and variable cost per unit (SBA). Assume monthly fixed costs of VND 3,300,000 (software, phone, part of a chat assistant's wage):

• Dealer tier: 3,300,000 ÷ 110,000 = 30 units a month to break even.
• Starter tier: 3,300,000 ÷ 40,000 = 82.5, so about 83 units a month.

This step turns water flosser dealer profit from a figure on paper into a concrete sales target. If your sales have settled at a higher level, talk to Inmax about committing to a higher tier.

Capital turnover shows how long your money sits in stock. According to the Corporate Finance Institute, days in inventory equals inventory divided by cost of goods sold, multiplied by 365; low turnover usually goes with slow sales and excess stock. For example, 30 units at the Dealer tier tie up VND 23,400,000: sell them within 30 days and that capital turns about 12 times a year; take 90 days and it turns only about 4 times.

Hold the listed price and reduce stock risk

A 10% discount on a VND 1,000,000 unit costs VND 100,000, while shipping and advertising stay the same. At the Dealer tier, the remaining profit falls from VND 110,000 to VND 10,000, before platform fees. That is why selling at the listed price, with no undercutting on marketplaces, is an Inmax partnership condition: a stable price level keeps every partner's margin from eroding. If you run a promotion, count any gift as a cost in step 3.

Several policy benefits reduce tied-up capital:

• Even a single carton is billed at the dealer price for your tier, enough to test each model.
• From the Dealer tier, slow-moving models can be swapped for better sellers in the same price group within 60 days of receiving the goods.
• From the Dealer tier, Inmax ships directly to your customers, so you need no warehouse.
• From the Distributor tier, 15-day payment terms from the third order reduce upfront cash.

Bundle accessories and choose models to lift profit per order

Shipping and advertising are usually charged per order, not per item, so a second product in the order spreads both costs. Models that suit this approach:

• M149Pro-BO: the M149Pro water flosser and an electric toothbrush on one shared stand.
• M141Pro: one handle works as a water flosser or takes an electric brush head; comes with 2 jet tips and 2 brush heads.
• M131: 350 ml tank, 2,000 mAh battery, 9 modes with a digital display, for customers shopping at the upper end.
• M159: 4 modes, 40–130 PSI, 34 units per carton, making trial-order capital easy to calculate.

Ask Inmax for the replacement tip list for each model, and compare specifications before settling your product mix.

Frequently asked questions

Is the 15–35% discount my net profit?

No. It is gross margin when you sell at the listed price; net profit also depends on platform fees, shipping, advertising, returns, fixed costs and tax.

What if a model sells slowly?

From the Dealer tier, slow models can be swapped for better sellers in the same price group within 60 days of receiving the goods.

Do dealers have to handle warranty repairs?

No technical work is needed: the 24-month warranty is handled by the Inmax hotline directly with end users, and partners keep no spare parts. How to support customers is covered in water flosser warranty for dealers.
