Are you pricing online items and want to make sure platform fees and shipping do not eat your profit?

List your item capital cost (wholesale price + shipping to you + packaging box/pouch). State your proposed selling price and the platform you sell on. Paste the prompt below to see your net take-home earnings and break-even point. Before you use it: Verify every fee and its base against your own current seller schedule. A cash withholding is not automatically the same as final tax expense, and missing return costs cannot be replaced with an invented buffer.

Calculate online shop contribution margin

Quick answer

Contribution per order = selling revenue minus product cost, packaging, verified platform and payment fees, seller-paid shipping, ads and other per-order costs. Contribution margin = contribution divided by selling revenue × 100. Use your current fee schedule; do not guess a tax or platform rate.

Provide each actual fee, its calculation base, and its source/effective period; do not rely on the platform name alone.

Calculate my per-order selling profit from only the costs and fees I provide. Do not guess current Shopee, Lazada or TikTok Shop fee rates.

INPUT
Selling price actually paid by buyer: ₱[AMOUNT]
Seller-funded discount/voucher: ₱[AMOUNT / 0 / TO CONFIRM]
Product cost: ₱[AMOUNT]
Packaging: ₱[AMOUNT]
Platform fees actually shown or verified: [FEE NAME + ₱AMOUNT OR % + BASIS]
Payment/transaction fees: [DETAILS / NONE / TO CONFIRM]
Seller-paid shipping/subsidy: ₱[AMOUNT / 0 / TO CONFIRM]
Ads/affiliate cost allocated to this order: ₱[AMOUNT / 0 / TO CONFIRM]
Taxes/withholding or other deductions shown: [DETAILS / NONE / TO CONFIRM]
Other per-order costs: [ITEM + AMOUNT / NONE]

VALIDATE FIRST
- Do not invent a platform fee, tax, commission, voucher share or shipping subsidy.
- If a percentage is supplied, state the base you apply it to. If the base is unknown, mark To confirm.
- Flag duplicate fees, missing amounts and percentages that cannot be calculated safely.

CALCULATE
1. Revenue basis used.
2. Each deduction separately.
3. Total variable cost/deductions.
4. Net profit per order.
5. Net margin = net profit ÷ revenue basis × 100.
6. Break-even selling price only if the supplied fee structure is sufficient to calculate it.

Show formula → substituted numbers → result for every calculation. Recompute once. Separate confirmed costs from To-confirm costs and label the result “Estimate from supplied figures” until all consequential fees are verified.

Illustrative example. Your answer may differ.

Arithmetic fixture, not a live platform fee: price PHP 300; product PHP 120; packaging PHP 10; seller-funded shipping PHP 20; advertising PHP 15; fixed fee PHP 5; proportional fee 10% of price. Contribution: PHP 100. Contribution margin: 33.33%. Excluded taxes, overhead, returns, and other unknown costs remain explicit.

Before you use it: Verify every fee and its base against your own current seller schedule. A cash withholding is not automatically the same as final tax expense, and missing return costs cannot be replaced with an invented buffer.

Philippine notes

Shopee and TikTok Shop transaction fees increase if you enroll in free shipping or cashback programs.
