Product Pricing Calculator
Guessing your price leaves money on the table or kills your margin. This calculator takes every real cost into account - product, packaging, shipping, payment processing fees, returns, and ad spend - and works backwards from your target profit margin to recommend a selling price. It also shows the minimum price you must charge to break even, and what happens to your margin when you run promotions or offer discounts.
How to use this tool
- 1Enter your product cost per unit - this is what you pay to make or buy the item, not including packaging or shipping.
- 2Add per-unit costs for packaging, shipping, and ad spend. Leave blank or enter 0 for any cost that does not apply.
- 3Set the payment processing fee percentage. Stripe and PayPal typically charge around 2.9%, Etsy around 6.5%, and Amazon 8-15% depending on the category.
- 4Set the returns allowance percentage - the portion of sales you expect to refund. A 2-3% allowance is typical for physical goods; higher for clothing or electronics.
- 5Enter your target profit margin as a percentage of the selling price (not markup). A 30-50% margin is common for physical product businesses.
- 6Read the recommended selling price, break-even price, and per-unit profit. Check the discount impact table to see what happens to your margin if you run promotions.
Formula used
Example
Product cost: 4.50, Packaging: 1.20, Shipping: 3.80, Payment fee: 6.5% (Etsy fee), Returns: 1%, Target margin: 40%. Fixed costs: 9.50. Recommended price = 9.50 / (1 - 0.065 - 0.01 - 0.40) = 9.50 / 0.525 = 18.10. Break-even: 10.27. At a 10% discount (16.29), margin drops from 40% to 27.7%.
Product cost: 8.00, Packaging: 1.50, Shipping: 4.50, Payment fee: 2.9%, Returns: 3%, Ad spend per unit: 5.00. Fixed costs: 19.00. Target margin: 50%. Recommended price = 19.00 / (1 - 0.029 - 0.03 - 0.50) = 19.00 / 0.441 = 43.08. Break-even: 20.19. Running a 20% promo drops margin from 50% to 37.5%.
Common use cases
- E-commerce sellers working out the minimum viable price before listing a new product
- Makers and craftspeople pricing handmade goods to ensure the business is profitable, not loss-making
- Retailers calculating the maximum wholesale buy price they can pay and still hit their target margin
- Amazon and marketplace sellers factoring platform fees into pricing before launching
- Product businesses checking whether a planned discount campaign will still leave acceptable profit
- Startup founders validating whether product margin can support paid advertising costs
Common mistakes
- Confusing margin with markup - a 50% markup on a 10.00 cost gives a price of 15.00 but only a 33% margin.
- Forgetting payment processing fees - Stripe, PayPal, Etsy, and Amazon each take 2.9-15% of every sale, directly reducing net revenue.
- Not accounting for returns - even a 2% return rate reduces effective margin and must be built into the price from the start.
- Using the same price across all sales channels - selling on Amazon at the same price as your own website usually means losing money on Amazon after fees.
- Underestimating ad spend - if actual cost per acquisition is higher than estimated, your real margin will be lower than calculated.
Frequently asked questions
What is the difference between profit margin and markup?
Markup is profit divided by cost. Margin is profit divided by selling price. A 100% markup on a 10.00 item gives a price of 20.00 and a 50% margin. They measure the same profit from different reference points. This calculator uses margin because it tells you what percentage of every sale you keep, which is the most actionable metric for pricing decisions.
What payment fee percentage should I enter?
It depends on your sales channel. Stripe and PayPal charge around 2.9% per transaction. Etsy charges a 6.5% transaction fee plus payment processing. Amazon charges 8-15% referral fees depending on category, plus FBA fulfillment fees per unit. Enter the combined percentage fee for your main channel, and add fixed-per-transaction fees to the shipping field if they are significant.
What is a good profit margin for physical products?
Consumer goods businesses typically target 30-60% gross margin. Simple high-volume products often achieve 20-30%. Premium or handmade products with a strong brand can sustain 50-70%. The minimum viable margin depends on your operating costs beyond the per-unit figures - rent, salaries, and overheads must also be covered from gross profit.
How do I account for Amazon FBA fees?
FBA fees include a referral fee (typically 8-15% of sale price) plus a fulfillment fee per unit (typically 3.00-6.00 for standard-size items, varies by weight). Add the referral percentage to the payment fee field, and add the fulfillment fee amount to the shipping cost field. This captures the full Amazon cost structure.
Is my data stored or uploaded?
No. All calculations run in your browser. Nothing is sent to any server. Refresh the page and all inputs are cleared.
What if my recommended price is higher than the market price?
If comparable products sell for less than your calculated price, you have a cost problem, not a pricing problem. Options: reduce unit cost through a better supplier or larger order quantities, reduce packaging or shipping costs, or target a premium segment willing to pay more. Pricing below your recommended price means accepting a margin below your target.
How accurate is this calculator?
It is accurate for the inputs you provide. Outputs are estimates - actual costs vary and inputs like returns are averages, not certainties. Use it to establish a pricing floor and a target, then monitor actual margin once real sales data is available.
Can I use this for digital products or services?
For digital products - downloads, software, courses - remove shipping and packaging and focus on payment fees and any platform commission. For service businesses, a Service Pricing Calculator that factors in hourly rate, utilisation, and overhead is a better fit.
