What is a Breakeven Calculator?

The breakeven point in stock trading is the price at which you neither profit nor lose on a trade — accounting for all transaction costs (brokerage, STT, GST, stamp duty, SEBI charges). Your actual buy price is not your breakeven — transaction costs push it slightly higher for a long position.

For business, the breakeven point in units is where total revenue equals total costs. It's calculated as: Fixed Costs / (Selling Price − Variable Cost per unit), also known as the Contribution Margin method. Knowing your breakeven helps set realistic sales targets and pricing strategies.

lightbulb Example Calculation
Scenario: Buy 200 shares at ₹490 with ₹20 brokerage, 0.1% other charges
1Buy value = 200 × ₹490 = ₹98,000
2Total charges = (₹20×2) + ₹98,000×0.1% = ₹138
3BE Price = (₹98,000 + ₹138) / 200 = ₹490.69
✓ Breakeven is ₹490.69 — must sell above this price to profit

Frequently Asked Questions

Stock and business breakeven explained

Why is my stock breakeven price higher than my buy price?
Every trade incurs transaction costs: brokerage (₹20 each way), STT (0.1% on delivery), exchange transaction charges (0.00345%), SEBI fees, GST on brokerage, and stamp duty. These are charged on both buy and sell sides. For a ₹5,000 trade, charges can add ₹20–30, making breakeven 0.4–0.6% above the buy price.
How is STT calculated for equity delivery trades?
For equity delivery: STT is 0.1% of trade value on both buy and sell sides. Buying ₹1,00,000 worth attracts ₹100 STT on purchase plus ₹100 on sale — ₹200 total. For intraday equity, STT is only 0.025% on the sell side. Futures have different rates: 0.01% on sell; equity options 0.0625% on exercised options sell side.
How do I interpret the contribution margin ratio for my business?
The CM ratio is the contribution margin as a percentage of selling price. If selling price is ₹200 and variable cost is ₹80, CM = ₹120, CMR = 60%. A higher CMR means more of each revenue rupee goes toward covering fixed costs and profit. SaaS businesses need high CMRs; high variable-cost businesses need volume to compensate.
