Enter your cost and selling price to estimate gross profit and understand whether the price leaves enough room after direct costs.
TechnWaves Profit Margin Calculator
Calculate profit margin, markup, selling price and profit amount for products or services with this online calculator.
Use this profit margin calculator to compare cost price, selling price, profit amount, margin percentage and markup. It helps you see whether a sale is actually profitable.
Small businesses often look only at selling price. This tool helps include cost, profit and pricing decisions in one simple calculation.
Margin and markup are not the same. Markup is calculated on cost, while margin is calculated on selling price. This difference matters when you quote products, bundles, service packages or discounted offers.
Add costs that quietly reduce profit: delivery, packaging, payment gateway fees, platform commission, wastage, returned items, repair visits and time spent on service delivery. A price that looks profitable before these costs may become weak after the real order is completed.
When should you use this tool?
- You buy products and need to decide a selling price.
- You want to check profit before offering a discount.
- You need to compare margin and markup.
- You want to review whether a service package is priced too low.
How to use this tool
- Enter the cost price or purchase cost.
- Enter the selling price or target sale value.
- Review profit amount, margin percentage and markup.
- Adjust price if discount, shipping, payment fees or wastage reduces profit.
- Use the final price in your quotation or invoice after review.
Example: shopkeeper pricing a product
A shopkeeper buys a product for ₹500 and sells it for ₹750. The profit is ₹250. The profit margin is based on selling price, while markup is based on cost price.
This difference matters. A 50% markup on cost does not mean 50% margin on selling price.
If the shop gives a Rs. 50 discount and spends Rs. 30 on delivery, the real profit changes quickly. Checking the revised margin before confirming the sale helps avoid low-profit orders.
Common mistakes to avoid
- Confusing margin with markup.
- Ignoring packaging, delivery or payment gateway fees.
- Giving discounts without checking remaining profit.
- Using purchase price but forgetting GST or shipping cost.
- Pricing every product with the same margin.
- Not reviewing slow-moving stock or service time cost.
Pricing note
The calculator shows basic profit numbers. Before final pricing, include all real costs such as GST impact, shipping, returns, wastage, platform fees, labour time and after-sales support.
Frequently Asked Questions
What is profit margin?
Profit margin shows profit as a percentage of selling price. It helps you understand how much of the sale remains as profit.
What is markup?
Markup shows profit as a percentage of cost price. It is often used when deciding how much to add above purchase cost.
Why are margin and markup different?
They use different bases. Margin uses selling price, while markup uses cost price. That is why the percentages are not the same.
Can this help set product price?
Yes. Enter cost and target selling price, then adjust until the margin makes sense for your business.
Should GST be included in cost?
It depends on your accounting and input credit situation. Ask your accountant how to treat GST for your business pricing.
Can service businesses use this?
Yes. Treat your time, tools, subcontractor cost and overhead as cost, then compare the service fee.
What margin is good?
There is no single good margin. It depends on industry, volume, risk, payment delay and operating cost.
Should I check margin before discounts?
Yes. A discount can quickly reduce profit, especially when the original margin is already small.
