About this converter

This converter takes a product or service’s cost and tells you what selling price to set for any chosen margin or markup. Or it goes the other direction: given an existing selling price and cost, what margin are you actually earning? Both math directions use the standard pricing identity: SP = Cost / (1 − Margin%) for margin-based pricing, or SP = Cost × (1 + Markup%) for markup-based pricing.

For Indian small businesses, the practical wins come from three angles. First, intentional pricing: don’t pull a number from thin air — start with cost, add desired margin, round to a psychological price point (599 over 590, 999 over 1000). Second, channel-specific pricing: D2C website vs Amazon vs marketplace platforms charge different commissions (15-25%), so your selling price must be set higher on those channels to maintain a constant net margin. Third, restaurants and dine-in: food cost should be 28-32% of pre-GST menu price (factor in wastage + staff meals); below 25% margin and you can’t cover rent and salaries; above 40% and you’re likely overpriced for the segment.

For GST-registered businesses, always quote selling prices ex-GST internally — the tax is added at billing and is not revenue. Net margin = (Selling Price − Cost − Operating Expenses − Taxes) ÷ Selling Price.

Margin vs Markup — Key Difference
Margin % = Profit / Selling Price × 100 (on SP)
Markup % = Profit / Cost Price × 100 (on CP)
SP = Cost / (1 − Margin%)  |  SP = Cost × (1 + Markup%)

Margin and markup are often confused. A 30% margin means 30% of the selling price is profit — the remaining 70% is cost. A 30% markup means you’ve added 30% of cost on top. 30% margin = 42.9% markup. In retail and GST invoicing, always clarify which basis you’re using.

GST Note: GST is charged on the selling price (ex-GST). The consumer pays SP + GST. Your revenue/turnover is the ex-GST price. Make sure your margin calculation is on the ex-GST selling price.

Pricing Strategy — Cost to Selling Price

Pricing is the single fastest profit lever. Raising prices 1% with the same volume drops 100% to the bottom line. Cutting costs 1% does too — but is much harder to execute. The cost-to-SP math is where pricing decisions either build margins or quietly erode them.

Two ways to derive selling price from cost: markup pricing (Cost × (1 + Markup%)) — used when sourcing decides the math. Margin pricing (Cost ÷ (1 − Margin%)) — used when target profitability decides the math.

Indian Industry Margin Benchmarks

Industry Typical Gross Margin Typical Net Margin Pricing Notes
FMCG / Grocery retail 15-25% 2-5% Volume game; MRP-led
Apparel & footwear retail 40-55% 15-20% SKU-mix matters
Restaurants (dine-in) 60-70% 8-15% Food cost ≤ 32% of menu
Jewellery 10-30% 3-8% Making charges drive margin
SaaS / Digital 70-90% 20-40% Pricing tiers + LTV
Professional services 50-70% 25-45% Hourly or project-based
D2C e-commerce 40-60% 5-15% CAC + platform fees eat margin

The 1% Rule: A 1% price increase with no volume drop adds the full 1% to bottom-line profit. A 1% cost cut delivers the same. On a ₹50 lakh business at 10% net margin, either lever is ₹50,000 more profit a year — every year. Tiny pricing tweaks compound.

Pricing Examples Across Channels

Example 1: Same Product, Three Channels

Cost ₹400 product. Pricing strategy for: (a) own website — SP ₹999 (60% margin); (b) Amazon — SP must be ₹1,199 to net the same after 17% commission; (c) physical retail with 30% trade margin — MRP ₹1,499. Different channels need different SPs to maintain the same net margin.

Example 2: Restaurant Menu Engineering

Pasta with food cost ₹140. Target 70% gross margin → SP ₹467 + 5% GST → menu price ₹490 (rounded). The 30% food cost ratio is what restaurant consultants use as the litmus test for menu pricing.

Example 3: Premium Pricing Test

Same ₹400 cost product. Mass-market at ₹799 (50% margin), 1,000 units/month = ₹3.99 L revenue. Premium re-position at ₹1,499 (73% margin), 400 units/month = ₹5.99 L revenue with HIGHER profit. Volume × margin × price is the actual goal — not just one metric.

Common Pricing Mistakes

  • Cost-plus only: Pricing by adding a flat markup ignores what customers will pay. Market-based pricing usually beats cost-plus.
  • Forgetting GST in the math: Quote ex-GST internally; add tax at billing. Confusing the two erodes margin invisibly.
  • Inventory shrinkage not priced in: Perishable retail loses 5-15% to spoilage/expiry. Cost should include this before applying margin.
  • Free delivery loss: A ₹50 delivery cost on a ₹400 product eats 12.5% of revenue. Either price it in or set a minimum order value.
  • Round-to-99 psychology: ₹999 outperforms ₹1,000 by typical 8-12% conversion lift. Always round selling prices to psychological points.

Cost & Selling Price — FAQ
What is the difference between margin and markup?
Margin (gross margin) is profit as a % of selling price. Markup is profit as a % of cost. For a product costing ₹100 sold at ₹143: margin = 43/143 = 30%, markup = 43/100 = 43%. The confusion causes significant pricing errors — always specify which you mean.
How do I price to maintain margin after a discount?
If you want 30% margin after a 10% discount, your MRP must allow for both. Formula: Pre-discount SP = Desired SP / (1 − discount%). So if desired SP (post-discount) = ₹1,429, pre-discount MRP = ₹1,429 / 0.90 = ₹1,588. Use the discount field in this converter to see the full picture.
Is GST included in the MRP?
Yes. In India, MRP (Maximum Retail Price) is GST-inclusive. The seller must not charge more than MRP. Your actual revenue (turnover for GST purposes) = MRP / (1 + GST rate). This converter handles both ex-GST and incl-GST scenarios.
