How to Read a Broker's Spread and Commission Schedule
Knowing how to read a broker's spread and commission schedule honestly is the single most useful skill for keeping your trading costs under control - yet most traders skim the numbers and move on without checking what they actually mean. This guide shows you how to pull a schedule apart, convert it into a real cost per trade, and avoid the common traps that make one broker look cheaper than it really is.
Why Spread and Commission Schedules Are So Easy to Misread
Broker pricing pages are written to look simple, but they're often doing a lot of quiet work to flatter the headline number. Common issues include:
- "From" spreads - the lowest spread ever recorded, not what you'll typically get
- Averages over a limited window - often calculated during the London session only, when liquidity is best
- Account-specific figures - a tight spread shown for a commission account, compared against a wider spread-only account elsewhere
- Instrument cherry-picking - EUR/USD numbers that don't reflect GBP/JPY or exotic pairs
- Commission shown as one-way - doubling in practice because it's charged on both entry and exit
None of this is necessarily dishonest marketing, but it does mean the number on the page is rarely the number you'll pay on a real trade. The fix isn't to distrust every broker - it's to treat published schedules as a starting point and verify them against live platform data and a proper comparison tool like /audit.html before you commit capital.
Breaking Down the Schedule Into Its Real Components
A spread and commission schedule usually has three or four separate line items, and you need all of them to get a true cost picture:
1. The spread - the gap between bid and ask, usually quoted in pips 2. The commission - a fixed fee per lot, sometimes tiered by monthly volume 3. Swap/rollover rates - charged for holding positions overnight (check /rates.html) 4. Platform or account fees - inactivity charges, withdrawal fees, data fees
Add these together for a realistic trade, not a theoretical best case. For example, with Pepperstone's Razor-style accounts, you'd expect a tighter raw spread plus a per-lot commission; with a standard account, the commission is usually folded into a wider spread instead. IG similarly offers both its own platform pricing and MetaTrader access, and the cost structure can differ between the two - so check which platform the published schedule actually refers to.
Converting Pips and Commission Into Pounds
Numbers in pips mean little until you convert them into your account currency at your typical trade size. The basic workflow:
- Pip value = (0.0001 / exchange rate) × lot size, adjusted for your account currency
- Spread cost = spread in pips × pip value
- Commission cost = commission per lot × lots traded (check if it's one-way or round-trip)
- Total cost per trade = spread cost + commission cost + any swap if held overnight
Do this for your actual average lot size and trade frequency, not a generic 1-lot example. A trader doing 0.1 lots ten times a day has a completely different cost profile to someone running 5-lot swing positions. This is exactly the calculation PipTax's /cost-impact.html tool automates, so you can see the annualised effect of a schedule rather than just a single trade snapshot.
Comparing Account Types Honestly
Most brokers now offer at least two account types, and comparing them fairly means running the same trade through both:
| Account type | Typical spread | Commission | Best suited to | |---|---|---|---| | Standard/spread-only | Wider | None | Lower frequency, simpler accounting | | Raw/ECN/Razor | Tighter, near-interbank | Fixed per lot | Active traders, scalpers |
The raw account usually wins for high-frequency trading once volume is high enough to make the commission worthwhile relative to the spread saved. But for occasional trades, the standard account's simplicity (one combined cost, no separate fee line) can work out similar or even cheaper. There's no universal answer - it depends on your volume, instrument mix, and holding times. Run both through the same calculation before choosing.
Checking for Hidden or Easily Missed Costs
Beyond the headline spread and commission, look for:
- Inactivity fees if you trade infrequently
- Currency conversion charges if your account currency differs from the instrument's base currency
- Withdrawal fees, especially for bank transfers or certain payment methods
- Minimum commission per trade, which can make very small positions disproportionately expensive
- Weekend or holiday swap multipliers, often 3x the normal rate on Wednesdays
These rarely appear in the main spread table and are usually buried in a separate fees page or the account terms. A genuinely honest comparison pulls all of these into one place - which is the whole point of checking a broker's full profile on /brokers/index.html rather than relying on a single marketing page.
Verifying What You've Read
Once you've worked through a schedule on paper, confirm it against reality:
- Open a demo account and screenshot live spreads during both quiet and volatile sessions
- Ask support directly whether published figures are averages, minimums, or guaranteed maximums
- Check the schedule's last-updated date - pricing pages go stale
- Cross-reference against PipTax's own methodology for how we collect and verify cost data, explained on /methodology.html
This step matters because demo and live pricing can diverge, and promotional spreads sometimes apply only for a limited introductory period.
Conclusion: Make the Schedule Work for You
Learning how to read a broker's spread and commission schedule honestly isn't about catching brokers out - it's about making sure the number you compare is the number you'll actually pay. Convert everything into pounds per trade at your real volume, add in swaps and fees, and verify live rather than trusting a single webpage. Trading costs compound over hundreds of trades, and even small misreadings add up. For live, comparable figures across brokers, run your own numbers through /audit.html before you fund any account - and remember that all trading carries risk, regardless of how competitive the cost schedule looks.
Key takeaways
- A spread and commission schedule only means something once you convert it into a per-trade, per-lot cost in your own currency
- Always check whether quoted spreads are 'average', 'typical', or 'from' figures, and ask for live data during volatile sessions
- Raw/ECN accounts with commission often beat standard accounts for active traders once you do the maths, but not always
- Swap rates, inactivity fees, and withdrawal charges belong in the same comparison as spreads and commissions
- Use PipTax's cost tool and broker pages for live, comparable figures rather than trusting marketing pages alone
- Document your findings so you can re-check pricing every few months, because schedules change
Frequently asked questions
- What's the difference between a spread-only account and a commission account?
- A spread-only account (often called 'standard') bakes the broker's cost into a wider spread with no separate fee. A commission account (often 'raw' or 'ECN') offers a much tighter spread closer to the interbank rate, but charges a fixed commission per lot. Neither is automatically cheaper - you need to add both components together and compare against your typical trade size.
- Why do spreads on a broker's website differ from what I see in my platform?
- Website figures are usually 'typical' or 'average' spreads taken during calm market hours, sometimes on a specific account type. Your live platform spread reflects current liquidity, volatility, and your actual account type, which can widen significantly around news events or session changes.
- Are commissions charged per trade or per lot?
- Almost always per lot (or per 100k/1M units traded), and often per side - so you may see a round-trip figure or a one-way figure that doubles when the position closes. Always check whether the published number is round-trip or one-way before comparing brokers.
- Do I need to worry about swap rates if I'm a day trader?
- If you close every position before the end of the trading day, swaps won't normally apply. But if there's any chance a trade runs overnight, or you hold swing positions, swap rates can add up and should be checked on /rates.html alongside spreads and commissions.
- How often should I re-check a broker's cost schedule?
- Review it at least every quarter, and immediately after any announcement of platform changes, new account tiers, or regulatory shifts. Brokers do revise schedules, and promotional pricing can quietly expire.
