Portfolio Break-Even Calculator
Calculate weighted break-even move needed for the whole portfolio.
Use this deterministic calculator to estimate the proportional move required for your portfolio to return to break-even.
Results
Break-even move required
+7.32%
Portfolio needs +7.32% (+$1,500.00) to break even.
- Total cost basis
- $22,000.00
- Total current value
- $20,500.00
- Required value change
- +$1,500.00
- Proportional price factor
- 1.0732x
Formula
Break-even Move % = ((Total Cost Basis - Total Current Value) / Total Current Value) × 100
Example
- Total portfolio cost basis: 22000
- Total current portfolio value: 20500
What does this mean?
- •Positive output means the portfolio needs that percentage gain to break even.
- •Negative output means you are already above break even by that amount.
- •This assumes holdings move proportionally from current weights.

What is a portfolio break-even?
Use this deterministic calculator to estimate the proportional move required for your portfolio to return to break-even. In practice, this means you can quantify portfolio break-even using total portfolio cost basis, and total current portfolio value without relying on hidden assumptions or black-box scoring.
Primary input set for this calculator: Total portfolio cost basis, Total current portfolio value.
How to calculate portfolio break-even
- 1.Step 1: Enter total portfolio cost basis with the timeframe/context you want to evaluate.
- 2.Step 2: Enter total current portfolio value with the timeframe/context you want to evaluate.
- 3.Step 3: Apply formula Break-even Move % = ((Total Cost Basis - Total Current Value) / Total Current Value) × 100.
- 4.Step 4: Interpret output together with risk, liquidity, and catalyst context.
Why this metric matters
This metric turns trade assumptions into explicit numbers for sizing, entry/exit planning, and portfolio discipline.
Pair this calculator with catalyst context from headlines, filings, and options flow to avoid relying on isolated numbers.
When to use this calculator
- ✓Before opening a new position where portfolio break-even impacts sizing or risk.
- ✓After a catalyst to quantify how much conditions changed versus your baseline.
- ✓When comparing setups across multiple tickers with one consistent formula.
- ✓During weekly review to keep decision-making tied to measurable inputs.
Common scenarios
Positive output means the portfolio needs that percentage gain to break even
Use this portfolio break-even workflow to quantify this scenario with deterministic inputs.
Negative output means you are already above break even by that amount
Use this portfolio break-even workflow to quantify this scenario with deterministic inputs.
This assumes holdings move proportionally from current weights
Use this portfolio break-even workflow to quantify this scenario with deterministic inputs.
Event reaction review
Recalculate portfolio break-even immediately after earnings, filings, or macro headlines.
Interpretation tips
- •Re-run portfolio break-even whenever key inputs change materially, not only when price moves.
- •Document assumptions so the same methodology can be repeated across watchlist names.
- •Use this metric as one layer in the decision stack, not as a standalone trade trigger.
Data caveats
- –Outputs are deterministic from your inputs; input quality determines output quality.
- –This page does not auto-adjust for broker fees, taxes, or slippage unless you include them in your assumptions.
- –Validate corporate action details, filing dates, and data freshness before acting on results.
FAQ
How does the portfolio break-even calculator work?
Portfolio Break-Even Calculator is deterministic and uses only your inputs (total portfolio cost basis, total current portfolio value). Formula: Break-even Move % = ((Total Cost Basis - Total Current Value) / Total Current Value) × 100.
What does this output tell me in practice?
Calculate weighted break-even move needed for the whole portfolio. Pair this with a stop-loss and thesis review, not just return math.
Does the portfolio break-even calculator use real-time market feeds?
No. This page does not auto-pull live data. You control all inputs and can rerun instantly as market conditions change.
Can I use this result directly for trading decisions?
Use it as a planning layer. Combine with position sizing, liquidity, and catalyst context before any execution.
