Cost Price ↔ Selling Price Converter
Convert between cost price and selling price using either markup % (on cost) or margin % (on revenue). Perfect for pricing products, quotes, and invoice preparation.
Cost-Plus Pricing vs Target Margin Pricing
Cost-plus pricing adds a fixed markup to your cost (simple, transparent, but ignores market demand). Target margin pricing starts from the market price and works backward to what you can afford to pay for the product. This converter supports both methods: use “markup % on cost” for cost-plus, and “margin % on selling price” for target margin pricing.
Selling Price (margin) = Cost / (1 − Margin%/100)
Cost (from SP, markup) = SP / (1 + Markup%/100)
Cost (from SP, margin) = SP × (1 − Margin%/100)
💡 What This Means for You
E-commerce sellers on Amazon India: factor in platform fees (8–15%), GST, shipping, and returns before applying markup. A 40% markup on cost sounds healthy, but after a 12% Amazon fee + 5% GST + 3% return buffer, your actual margin may be under 10%. Always build a full cost sheet before setting prices.
