A guaranteed stop-loss sounds like free insurance, but it isn’t free at all. Spread betting providers charge a premium for guaranteeing your exit price, and that charge quietly eats into every position where you use one.
The Premium Charge Calculator shows exactly what a guaranteed stop costs on your specific position, in either the fixed-points or percentage-of-position charging model your provider uses.
It also compares that cost directly against a standard, non-guaranteed stop with realistic slippage, so you can see the actual trade-off you’re making rather than assuming a guaranteed stop is automatically worth it.
📊 How to Use the Premium Charge Calculator
Enter your stake per point and your intended stop-loss distance in points, then select which premium model your provider uses: a fixed number of extra points, or a percentage of your position value at the stop.
Check your provider’s terms carefully — some charge the premium as extra points added to your stop distance, others as a straight percentage of your position size at that stop level.
Finally, enter a realistic slippage estimate for a standard stop in a fast-moving market, so the comparison between guaranteed and standard stops reflects real conditions, not an idealized best case.
🔢 Calculator Fields Explained
Stake Per Point – your position size, expressed as currency won or lost per point of price movement.
Stop-Loss Distance – how many points away from your entry price your stop is set.
Guaranteed Stop Premium Type – whether your provider charges the premium as fixed extra points or as a percentage of your position value.
Premium (extra points) – the additional points added to your effective stop cost under the fixed-points model.
Premium (% of position at stop) – the percentage fee charged on your position value at the stop level, under the percentage model.
Expected Slippage on a Standard Stop – your estimate of how many extra points a normal stop could be missed by during fast market moves.
💰 Understanding the Results
| Result Field | What It Tells You |
|---|---|
| Guaranteed Stop Premium Cost | The exact fee charged for guaranteeing your exact stop price |
| Max Loss With Guaranteed Stop | Your true worst-case loss, including the premium fee |
| Max Loss With Standard Stop | Your realistic worst-case loss on a standard stop, including expected slippage |
| Extra Cost of Guaranteeing the Stop | The difference between the two — what you’re really paying for certainty |
The Extra Cost row is the number that matters most, since it converts an abstract “premium fee” into a direct comparison against the realistic alternative of a standard stop.
In genuinely fast-moving or gapping markets, slippage on a standard stop can easily exceed the guaranteed stop premium, making the guarantee the cheaper option overall.
A guaranteed stop is not automatically expensive or automatically worth it — it depends entirely on how volatile the specific market you’re trading actually is.
📐 Calculation Formulas
| Charging Model | Formula | Notes |
|---|---|---|
| Fixed Points Premium | stake per point × premium points | Simple, predictable regardless of stop distance |
| Percentage Premium | (stake per point × stop distance) × premium % | Scales with position size and stop distance |
| Guaranteed Max Loss | (stake × stop distance) + premium cost | Your true worst case, fully certain |
| Standard Max Loss (realistic) | stake × (stop distance + expected slippage) | Not guaranteed — can still be worse in extreme gaps |
The percentage premium model scales with both your stake and your stop distance, so a wider stop under that model costs proportionally more to guarantee than a tight stop does.
Because of this scaling difference, the fixed-points model tends to favor traders using wide stops, while the percentage model tends to favor traders using tight stops.
📝 Practical Examples
Example 1 – Fixed Points Model: £10/point stake, 50-point stop, 3-point premium. Premium cost = £30. Guaranteed max loss = £530.
Example 2 – Percentage Model, Same Position: Same £10/point stake and 50-point stop, but a 0.3% premium instead. Premium cost = £1.50. Guaranteed max loss = £501.50 — far cheaper here than the fixed-points version.
Comparing Examples 1 and 2 shows why it’s worth checking exactly which premium model your provider uses before assuming a “typical” premium cost from a different broker applies to you.
Example 3 – Volatile Market, Standard Stop: Same £10/point stake, 50-point stop, but 15 points of expected slippage in a fast-moving market. Standard max loss = £650 — worse than either guaranteed stop above.
Example 4 – Calm Market, Standard Stop: Same position, but only 2 points of expected slippage in a calm market. Standard max loss = £520. In this calmer scenario the standard stop actually beats the fixed-points guaranteed stop’s £530 max loss, showing the decision depends heavily on expected volatility.
💡 Tips & Best Practices
Reserve guaranteed stops for genuinely volatile instruments or around known event risk, like earnings releases or major economic data, where slippage risk is highest.
For calmer, liquid markets, a standard stop with realistic (low) slippage expectations is often the cheaper choice over many trades.
Always check whether your specific provider’s premium is refunded if the guaranteed stop is never triggered, since policies vary.
Running this comparison before placing a position, rather than relying on a general rule of thumb, lets you make the guaranteed-stop decision on the numbers for that specific trade.
Factor the premium cost into your overall risk-per-trade calculation, not just your stop distance, since it directly changes your true maximum loss.
Revisit your slippage assumptions periodically, since typical slippage during high-impact news events can be dramatically higher than in normal conditions.
- Widen your slippage estimate around scheduled news events specific to your instrument
- Recalculate whenever your provider changes its guaranteed stop premium structure
⚠️ Common Mistakes to Avoid
Assuming Guaranteed Stops Are Always Worth the Cost
Some traders use guaranteed stops on every position out of habit, regardless of the instrument’s actual volatility.
Paying a guaranteed stop premium on a calm, liquid instrument where slippage is genuinely rare is often just an unnecessary recurring cost.
Reserve the guarantee for situations where slippage risk is real and material.
Underestimating Slippage on Standard Stops
Traders sometimes assume a standard stop will execute at almost exactly the stop price, even around known volatility events.
Underestimating slippage on a standard stop leads to comparing the guaranteed premium against an unrealistically cheap alternative.
Use a slippage estimate based on the instrument’s actual historical gap behavior, not a generic assumption.
Not Checking Which Premium Model Applies
Fixed-points and percentage-based premium models can produce very different costs for the exact same position.
Assuming your previous provider’s premium model applies at a new provider is a common and costly mistake when switching platforms.
Ignoring Premium Cost in Overall Risk Sizing
Some traders size their position based only on stop distance, forgetting the premium adds directly to their true maximum loss.
Always include the premium cost in your per-trade risk budget, not just the raw stop-distance loss.
🎯 When to Use This Calculator
Use this calculator before placing any spread bet where you’re deciding between a standard and a guaranteed stop, especially around scheduled news events or in historically volatile instruments.
Experienced spread bettors often treat the guaranteed stop premium the same way they’d treat any other trading cost — worth paying only when the specific situation actually justifies it.
It’s also useful for comparing providers, since premium structures and rates differ meaningfully across brokers.

❓ Frequently Asked Questions
Is a guaranteed stop-loss always more expensive than a standard stop?
Not necessarily — in genuinely volatile conditions, slippage on a standard stop can exceed the guaranteed stop’s premium cost.
The comparison depends heavily on the specific instrument’s volatility and whether you’re trading around scheduled news events.
Why do some providers charge a percentage and others a fixed points fee?
It reflects different risk models — a percentage fee scales with position size and stop distance, while a fixed points fee stays constant regardless of either.
A trader using very wide stops will often find the percentage model cheaper, while a trader using tight stops may find the fixed-points model cheaper.
Always check your specific provider’s documentation rather than assuming one model universally applies.
Do I get the premium back if my guaranteed stop is never triggered?
This varies significantly by provider — some charge the premium only if the stop is actually triggered, others charge it upfront regardless of outcome.
Confirm your specific provider’s policy, since it materially changes whether a guaranteed stop is worth using on lower-probability setups.
Should I use a guaranteed stop around major economic data releases?
This is often when guaranteed stops are most valuable, since gap risk and slippage on standard stops both increase sharply around scheduled high-impact news.
Many traders reserve guaranteed stops specifically for these windows rather than using them on every position.
Does a wider stop always mean a higher premium?
Under a percentage-based premium model, yes — a wider stop increases the position value at the stop level, which increases the percentage-based fee.
Under a fixed-points model, the premium stays the same regardless of how wide your stop distance is.

The UI on this calculator is clean enough, but I’m noticing the conversion funnel could be optimized. Most affiliates pushing spread betting products see higher LTV when the premium charge comparison is visualized upfront rather than buried in results. The field labels are accessible, sure, but the onboarding friction here is real—users have to understand three separate concepts (stake per point, stop distance, premium type) before they even see a number. I tested this flow across LatAm markets last quarter and found that pre-populating the slippage field based on market volatility tier reduced abandonment by roughly 18%. The calculator itself performs well on mobile, which matters since 62% of affiliate traffic in emerging regions comes through phones. One thing holding back conversion though: no clear CTA after results. Users see their max loss comparison and then what? They need a button routing them to provider comparison or a broker affiliate link. Right now it’s just dangling there. The trust factor improves significantly once you add third-party verification badges or mention which major brokers use each premium model. That social proof element moves the needle on affiliate payouts.
You’re hitting on something important about affiliate funnel design that doesn’t get discussed enough. The pre-population idea based on volatility tier is sharp—that’s essentially reducing cognitive load at the decision point. On the CTA gap you mentioned, you’re right that post-calculation handoff is where most calculators fail. We’re planning an update that includes provider-specific premium comparisons right in the results section, so users can see not just their cost but which brokers charge what. Regarding the mobile abandonment data, we’ve seen similar patterns with financial calculators generally. One thing worth testing on your end: does adding a ‘save this scenario’ feature improve return visits? We’ve noticed traders often want to compare multiple what-if positions before committing capital. The verification badges suggestion is solid too—we’re working with the FCA and CySEC to include compliance checkmarks. Would be curious whether your LatAm conversions improved more from the badges themselves or from the implied legitimacy they signal.
Thanks, that’s helpful context on the CTA redesign. The save-scenario feature would definitely drive repeat traffic—I’ve noticed traders bookmarking calculators when they’re stress-testing multiple position sizes. On the badges, in my testing the FCA checkmark moved conversion more than I expected, probably 8-12% lift. The implied legitimacy angle is huge in LatAm where broker trust is fragile. One follow-up: are you planning to surface which premium models are ‘sharp-friendly’ vs ‘recreational-friendly’? That segmentation could help affiliates target the right audience segments.
The segmentation angle is something we’re definitely exploring. The data suggests fixed-points premiums appeal more to position-sizing traders who use consistent stop distances, while percentage models attract scalpers and shorter-duration traders. We’re working on a broker profile section that flags these tendencies, which could be useful for your affiliate targeting. FCA badges performing at 8-12% is strong—we’re rolling those out across all jurisdiction-regulated operators by Q2. Worth noting: your observation about broker trust in LatAm is backed by our market data. Operators licensed in Panama or Belize see significantly higher churn when they don’t display licensing prominently. The save-scenario feature is live in beta now if you want to test it with your traffic.
Spread betting premium charges murder CS:GO betting lines. I had a 500k stack on Heroic to beat FaZe at +180, map pool favored them heavy, but the guaranteed stop premium on my position made the effective odds worse than the opening line. Fixed points model hit me for an extra 25 points on a 100-point stop. Never again. Now I just use standard stops and eat the slippage when maps are vetoed. The percentage model is garbage too if you’re stacking position sizes—scales too fast. Better off taking the gap risk during esports events than paying for certainty you don’t actually need. Only time guaranteed stops matter is illiquid markets where spreads widen 200+ pips in 2 seconds. Dota 2 Grand Final betting, sure. Regular league play? Save your premium.
Regarding esports betting specifically, your point about fixed-points premiums on wider stops is mathematically solid. The 25-point hit on a 100-point stop works out to 25% of your stop distance as a fee, which is brutal when you factor in the actual slippage risk on standard stops during low-liquidity periods. You’re right that illiquid markets justify the guarantee differently. CS:GO line movement during map veto phases can genuinely spike 150+ points in seconds, so in that context the premium becomes insurance rather than a tax. One nuance though: the percentage model actually favors your tighter stops in esports if you’re setting them at 40-50 points. The math flips because the percentage fee stays smaller in absolute points even though it scales proportionally. For rosters shifts or stand-in situations where line movement is predictable, that might actually save you money compared to the fixed-points model your broker uses. Worth checking their premium structure before your next Dota Grand Final ticket.
