Break-Even Calculator — Break-Even Point Analysis Tool

This calculator has three modes — select the one that matches your situation using the Calculator Mode dropdown at the top.

Trade mode is for stocks, crypto, forex, or any asset where you buy at one price and sell at another. Enter your Entry Price, the total Fees you will pay (combine the buy-side and sell-side commissions), and the Position Size in units (shares, coins, contracts). The calculator will tell you the exact price at which you need to exit to recover your costs, and the percentage move required from your entry to reach that point.

Betting mode is designed for sports bettors and matched bettors. Enter your Stake and the Decimal Odds you were offered. The calculator returns the implied probability embedded in those odds — which is the minimum win rate you need to break even over a large sample. It also shows your potential profit on a winning bet.

Business mode is for entrepreneurs, freelancers, and SaaS operators. Enter your monthly Fixed Costs (rent, salaries, software subscriptions), Variable Cost per Unit (materials, payment processing fees, fulfilment), and the Selling Price per Unit. The calculator returns the contribution margin per sale, the number of units you need to sell each month to cover all costs, and the corresponding monthly revenue target.

Trade Mode

1. Fees per Unit = Total Fees ÷ Position Size
2. Break-Even Price = Entry Price + Fees per Unit
3. Price Move Needed (%) = (Break-Even Price − Entry Price) ÷ Entry Price × 100

For short positions, fees still push the break-even in the unfavorable direction: you need the price to fall slightly further than your entry to cover costs.

Betting Mode

1. Implied Probability (%) = (1 ÷ Decimal Odds) × 100
2. Break-Even Win Rate = Implied Probability (they are identical)
3. Profit if Win = Stake × (Decimal Odds − 1)

The implied probability is the baked-in edge that the bookmaker builds into the odds. A bet at decimal odds of 2.0 requires a 50% win rate to break even. At 1.91 (common on European exchanges), the required win rate rises to 52.36%.

Business Mode

1. Contribution Margin = Selling Price per Unit − Variable Cost per Unit
2. Break-Even Units = Fixed Costs ÷ Contribution Margin
3. Break-Even Revenue = Break-Even Units × Selling Price per Unit

The contribution margin tells you how much each sale contributes to covering fixed overhead. Once total contributions equal fixed costs, you are at break-even — every sale after that is profit at the margin rate.

Example 1 — Crypto Trade Break-Even

You buy 0.5 BTC at $60,000 and pay $150 total in exchange fees (entry + exit).

• Fees per unit = $150 ÷ 0.5 = $300 per BTC
• Break-even price = $60,300
• Price move needed = ($300 ÷ $60,000) × 100 = 0.5%

BTC needs to rise just 0.5% before you are profitable. This seems small, but on a $3,000 swing trade with tight stops, knowing the exact break-even is critical for stop placement.

Example 2 — Sports Bet Break-Even Win Rate

A bookmaker offers decimal odds of 1.91 on a soccer match (equivalent to -110 American).

• Implied probability = 1 ÷ 1.91 × 100 = 52.36%
• Break-even win rate = 52.36%
• Profit on a $100 winning bet = $100 × (1.91 − 1) = $91

This means you must win more than 52.36% of your bets at these odds to be profitable long-term. If your model gives you a 55% probability on this outcome, you have a positive expected value edge of roughly 2.6 percentage points.

Example 3 — SaaS Business Break-Even

A SaaS startup has $8,000 per month in fixed costs (server, salaries), charges $49/month per subscription, and incurs $4 in variable costs per customer (payment processing, support).

• Contribution margin = $49 − $4 = $45 per subscription
• Break-even units = $8,000 ÷ $45 = 178 subscribers (rounded up)
• Break-even revenue = 178 × $49 = $8,722 / month

Every subscriber beyond 178 generates $45 of pure operating profit. At 300 subscribers, the company earns (300 − 178) × $45 = $5,490 per month in profit.
