Key Financial Terms

Cost Price (CP): The total amount of money it costs a manufacturer, trader, or retailer to produce or purchase an item.
Selling Price (SP): The final cash amount a buyer pays to purchase the item.
Marked Price (MP): The original price printed on an item's tag (MRP or List Price) before any promotional discounts are applied.

Profit & Loss Formulas Explained

A Profit occurs when the Selling Price is greater than the Cost Price (SP > CP). A Lossoccurs when the Cost Price is greater than the Selling Price (CP > SP). Here is the math powering your results:

1. Calculating Profit

When you sell an item for more than it cost to acquire.

Profit = SP - CP

Profit % = (Profit / CP) × 100

2. Calculating Loss

When you are forced to sell an item for less than it cost.

Loss = CP - SP

Loss % = (Loss / CP) × 100

Discount Formulas

A discount is a reduction in the Marked Price. The golden rule of commercial math is that discounts are always calculated on the Marked Price (MP), never on the Cost Price.

Discount = MP - SP

Discount % = (Discount / MP) × 100

Real-Life Worked Examples

Example 1: Basic Profit Margin

Scenario: A mobile shop owner in Delhi buys a smartphone for ₹10,000 (Cost Price) and sells it to a customer for ₹12,500 (Selling Price). What is the profit percentage?

CP: ₹10,000
SP: ₹12,500
Step 1 (Amount): ₹12,500 - ₹10,000 = ₹2,500 Profit
Step 2 (Percentage): (₹2,500 / ₹10,000) × 100 = 25%

Result: The shop owner made a 25% profit margin.

Example 2: Applying a Festive Discount

Scenario: A pair of shoes has a price tag (Marked Price) of ₹2,000. During a Diwali sale, the store offers a 15% discount. What is the final Selling Price?

MP: ₹2,000
Discount %: 15%
Step 1 (Discount Amount): 15% of ₹2,000 = (15 / 100) × 2000 = ₹300
Step 2 (Selling Price): ₹2,000 (MP) - ₹300 (Discount) = ₹1,700

Result: The final Selling Price for the customer is ₹1,700.

Example 3: Calculating a Loss

Scenario: You bought a bicycle for ₹5,000. A year later, you decide to sell it second-hand for ₹3,500. What is your loss percentage?

CP: ₹5,000
SP: ₹3,500
Step 1 (Loss Amount): ₹5,000 (CP) - ₹3,500 (SP) = ₹1,500 Loss
Step 2 (Percentage): (₹1,500 / ₹5,000) × 100 = 30%

Result: You incurred a 30% loss on the sale.

Frequently Asked Questions

How do I calculate profit margin?▼

To calculate profit margin, subtract your Cost Price (CP) from the Selling Price (SP) to get the profit amount. Then, divide that profit amount by the Cost Price and multiply by 100 to get the percentage.

Is discount calculated on cost price or marked price?▼

Discounts are always calculated on the Marked Price (MP), also known as the list price or tag price, never on the Cost Price.

Can I have a profit and a discount at the same time?▼

Yes! A business owner often marks up the price of an item above the Cost Price to create a Marked Price. They can then offer a discount on that Marked Price to the customer, and as long as the final Selling Price is higher than the original Cost Price, they still make a profit.

What is the difference between markup and profit margin?▼

Markup is the percentage added to the Cost Price to determine the Selling Price. Profit margin is the percentage of the Selling Price that represents actual profit. While related, the percentages will be different.

How is loss percentage calculated?▼

Loss percentage is calculated by finding the absolute loss amount (Cost Price - Selling Price), dividing it by the original Cost Price, and multiplying the result by 100.
