Adding GST to Base Amount
This calculation finds the total amount after adding GST to a base amount.
Formula: Base Amount × (1 + GST Rate / 100)
Example: For a base amount of ₹1000 with 18% GST:
GST Amount = 1000 × (18 / 100) = ₹180
Total Amount = 1000 + 180 = ₹1180
Removing GST from Total Amount
This calculation finds the original base amount by removing GST from a total amount.
Formula: Total Amount ÷ (1 + GST Rate / 100)
Example: For a total amount of ₹1180 including 18% GST:
Base Amount = 1180 ÷ (1 + 18 / 100) = 1180 ÷ 1.18 = ₹1000
GST Amount = 1180 - 1000 = ₹180

About Profit & Loss Calculations
Profit Calculation
Profit occurs when the selling price (SP) is greater than the cost price (CP).
Profit Amount: Selling Price - Cost Price
Profit Percentage: (Profit Amount ÷ Cost Price) × 100%
Example: If CP = 100 and SP = 125
Profit = 125 - 100 = 25
Profit % = (25 ÷ 100) × 100% = 25%
Loss Calculation
Loss occurs when the selling price (SP) is less than the cost price (CP).
Loss Amount: Cost Price - Selling Price
Loss Percentage: (Loss Amount ÷ Cost Price) × 100%
Example: If CP = 100 and SP = 80
Loss = 100 - 80 = 20
Loss % = (20 ÷ 100) × 100% = 20%
Tips for Businesses
- When calculating profits, remember to account for all costs, including overhead, taxes, and other expenses.
- Markup is different from profit margin. Markup is calculated on the cost price, while profit margin is calculated on the selling price.
- A healthy profit margin varies by industry but generally ranges from 10% to 20% in retail.
- Regularly analyze your profit and loss to identify trends and make informed business decisions.
