A partial hedge is a middle ground between doing nothing and fully hedging a bet. Instead of placing an opposing wager large enough to guarantee an identical profit no matter what happens, you hedge only a portion of your position, keeping some exposure to your original bet’s bigger payout.

This calculator shows you exactly what a partial hedge does to your outcomes on both sides, and includes a reverse mode that solves for the exact hedge stake needed to guarantee a specific minimum profit if your original bet loses.
Whether you’re trying to protect part of a big pre-season futures bet or looking to lock in some value on a live in-play swing, understanding the partial hedge trade-off is essential before placing the second bet.
π How to Use the Partial Hedge Calculator
Enter your Original Stake and the decimal odds for both your original bet and the hedge bet you’re considering. Then choose whether you want to specify a hedge percentage directly, or solve for the exact stake needed to guarantee a target profit.
A 100% hedge (a full hedge) guarantees the same profit no matter which side wins, while a partial hedge deliberately keeps the two outcomes unequal.
The results panel shows both outcomes side by side, along with a full-hedge comparison, so you can see precisely how much extra upside you’re keeping by not hedging completely.
π’ Calculator Fields Explained
Original Stake – The amount wagered on your original, already-placed bet.
Original Bet Decimal Odds – The odds you received on your original wager.
Hedge Bet Decimal Odds – The odds currently available for the opposing outcome you’re considering betting on.
Hedge Percentage – What fraction of a full (100%) hedge stake you want to actually place.
Target Profit If Hedge Wins – In target mode, the guaranteed minimum profit you want if your original bet ends up losing.
π° Understanding the Results
| Result Field | What It Means |
|---|---|
| Hedge Stake to Place | The actual amount to bet on the hedge side at your chosen percentage or target |
| Full Hedge Stake (100%) | What a complete, profit-equalizing hedge would require, for comparison |
| Profit If Original Wins | Your net result if your original bet’s outcome happens |
| Profit If Hedge Wins | Your net result if the hedge bet’s outcome happens instead |
The comparison table is where the real decision-making happens, since it shows you the two outcomes side by side rather than collapsing them into a single guaranteed number.
A partial hedge means you are deliberately choosing to keep unequal outcomes β read both rows of the table carefully before placing the second bet.
Placing exactly a 50% partial hedge typically keeps roughly half your original upside while still meaningfully reducing your downside. The exact trade-off always depends on both sets of odds.
π Calculation Formulas
| Metric | Formula |
|---|---|
| Full Hedge Stake | (Original Stake Γ Original Odds) Γ· Hedge Odds |
| Partial Hedge Stake | Full Hedge Stake Γ (Hedge % Γ· 100) |
| Profit If Original Wins | (Original Stake Γ Original Odds β Original Stake) β Hedge Stake |
| Profit If Hedge Wins | (Hedge Stake Γ Hedge Odds β Hedge Stake) β Original Stake |
Solving for a target profit simply rearranges the “Profit If Hedge Wins” formula to isolate the required hedge stake directly.
Once you understand these four formulas, you can reconstruct any partial hedge scenario by hand, even without the calculator in front of you.
π Practical Examples
Example 1 – 50% partial hedge: A $100 stake at 3.50 odds against a 1.80 hedge. A full hedge would require $194.44. A 50% partial hedge stakes $97.22. If the original wins, profit is $152.78. If the hedge wins, profit is $-2.78.
Example 2 – Full hedge for comparison: Same bet, but hedging 100%. Both outcomes settle to an identical $95.56 profit, regardless of which side wins.
The partial hedge kept over $57 of extra upside on the original bet side, at the cost of a small loss instead of a guaranteed profit if the hedge side wins.
Example 3 – Solving for a target: Same original bet, but the user wants a guaranteed $20 profit if the hedge wins. The calculator solves for a required hedge stake of $150.00, leaving a $130.00 profit if the original bet wins instead.
Solving directly for a target profit removes the guesswork of adjusting a percentage slider by trial and error. It tells you exactly what to stake for the specific floor you want.
π‘ Tips & Best Practices
Decide your hedge percentage philosophy before odds move against you β deciding in the moment, under pressure, often leads to inconsistent or emotional hedge sizing.
Use the target profit mode when you have a specific dollar figure in mind you want protected, rather than an arbitrary percentage of the full hedge.
Always compare your partial hedge outcome against the full hedge outcome side by side, so you clearly understand exactly how much guaranteed profit you’re giving up for extra upside.
- Reassess hedge odds close to the actual event, since they can move significantly from when you first considered hedging
- Consider your original bet’s win probability, not just the odds, when choosing how large a partial hedge to place
Deciding your hedge percentage philosophy in advance, before odds move, consistently produces better outcomes than deciding under time pressure.
Finally, remember that a partial hedge is a risk-management decision, not a guaranteed-profit strategy β it only changes the shape of your risk, not the underlying probabilities.
β οΈ Common Mistakes to Avoid
Confusing a partial hedge with a full hedge
Some bettors place what they believe is a “safe” hedge without realizing they’ve only covered a fraction of the position needed for a guaranteed equal profit.
Assuming a partial hedge behaves like a full hedge is a common and costly misunderstanding of how hedge sizing actually works.
Always check the full-hedge comparison figure so you know exactly how far your actual hedge stake falls short of a complete lock-in.
Ignoring the downside outcome entirely
It’s easy to focus only on the outcome you expect to happen and overlook what a partial hedge actually leaves you exposed to on the other side.
Ignoring the less-likely outcome’s actual profit or loss figure is one of the costliest oversights in partial hedge planning.
Overlooking the less-favored outcome’s real number is consistently the costliest mistake in partial hedge planning. Both rows of the comparison table matter, not just the one you expect to happen.
π― When to Use This Calculator
Use this calculator any time you’re holding an existing bet and considering a partial second wager to reduce risk while keeping some upside, particularly for futures bets, live in-play swings, or any position where a full hedge would eliminate too much of your original edge.
A partial hedge isn’t indecision β it’s a deliberate choice about exactly how much certainty you’re willing to trade for upside.

β Frequently Asked Questions
What’s the difference between a partial hedge and a full hedge?
A full hedge stakes exactly enough on the opposing outcome to guarantee an identical profit either way, while a partial hedge stakes less than that amount on purpose.
For example, hedging at 50% of the full hedge stake keeps roughly half your original upside while still meaningfully reducing your worst-case outcome.
When does a partial hedge make more sense than a full hedge?
It tends to make sense when you still believe your original bet has a meaningfully better-than-implied chance of winning, but want to reduce variance rather than eliminate it entirely.
A bettor who placed a long-odds futures bet that’s now well-positioned might partially hedge to guarantee some return while still chasing the bigger original payout.
Can a partial hedge ever result in a loss on both outcomes?
Yes, if the hedge odds are poor enough or the percentage chosen is too small, it’s possible for one or even both outcomes to show a net loss.
Always check both rows of the results table, since a poorly sized partial hedge can leave you exposed to a loss on the less-favored side.
This is exactly why the target-profit mode exists β it guarantees you never go below a number you explicitly chose.
How do I decide what hedge percentage to use?
Consider how much guaranteed downside protection you want against how much of your original upside you’re willing to give up, then test a few percentages in the calculator.
There is no single correct hedge percentage β it depends entirely on your personal risk tolerance and confidence in the original bet.
Does hedge percentage need to be a round number?
No, the calculator accepts any percentage, and in target mode you can skip percentages entirely and just enter your desired guaranteed profit figure directly.
This is often more useful in practice, since most bettors think in terms of dollars protected rather than an abstract percentage of a theoretical full hedge.
