How We Rate and Compare Brokers: Our Cost-First Methodology

Most broker comparison sites rank brokers by who pays the most for placement. We don't. Our broker review methodology starts with a single question: how much does it actually cost you to trade here?

That might sound obvious, but you'd be surprised how often trading costs get buried under flashy platform features and bonus offers. For a beginner putting $100 to $500 into a live account, the difference between a 0.8 pip spread and a 1.5 pip spread on EUR/USD can quietly eat 30-40% of your profit margin on short-term trades. That's not a small detail. That's the difference between a strategy working and not working.

What 'True Trading Cost' Actually Means

True trading cost isn't just the spread (the gap between the buy and sell price of an asset). It's the full picture:

• Spreads on the pairs or instruments you actually trade
• Commissions charged per trade or per lot
• Overnight financing (called swap rates or rollover fees) if you hold positions past market close
• Deposit and withdrawal fees that reduce your usable capital
• Inactivity fees that drain dormant accounts
• Minimum deposit requirements that affect who can even get started

Our trading cost scoring system captures all six of these dimensions for every broker we evaluate. No single number tells the whole story, which is why we score each dimension separately before combining them into a final rating.

1. Typical Spreads on Major Pairs

Spreads are the most immediate cost you'll face as a trader. Think of it like the markup at a currency exchange booth at an airport - the difference between what you pay and what the market price actually is. We measure typical spreads (not minimum or best-case spreads) on EUR/USD, GBP/USD, USD/JPY, and USD/CHF during active trading hours, specifically the London-New York overlap between 13:00 and 17:00 UTC.

A broker advertising a 0.0 pip spread might charge $7 commission per lot. A broker with a 1.2 pip spread might charge zero commission. We convert everything to a comparable cost-per-standard-lot figure so you can actually compare apples to apples.

2. Commission Structure

Some brokers charge a flat commission per trade. Others build their profit into the spread. And some do both. We score commission structures on transparency and total cost, not just on whether they're labeled as 'zero commission' (a term that's often misleading).

3. Overnight Financing Rates

If you hold a trade open past the daily rollover time (usually 22:00 GMT), most brokers charge a swap fee. These fees are often expressed as an annual percentage rate but applied daily. On leveraged positions, they add up fast. We sample swap rates on five major pairs and score brokers on how competitive their rates are relative to the interbank benchmark.

4. Deposit and Withdrawal Fees

A broker that charges $25 per wire withdrawal is effectively taxing every profit you take out. We check fees for the most common deposit and withdrawal methods globally: credit/debit cards (Visa and Mastercard), e-wallets (Skrill, Neteller, PayPal where available), and bank wire transfers. Currency conversion fees are also factored in, since many international traders deposit in a currency different from their account base currency.

5. Inactivity Fees

This one catches a lot of beginners off guard. Several brokers charge a monthly fee if you don't place a trade for 3-12 months. For someone learning on a demo account or taking a break from trading, this can quietly drain a live account. We score brokers on whether they charge inactivity fees, how high they are, and how quickly they kick in.

6. Account Minimum Requirements

A $500 minimum deposit isn't a big deal if you have $500. But for a beginner in an emerging market, or someone who just wants to test the waters with $50, it's a real barrier. We score minimums on a sliding scale - lower is better, but we also consider whether the minimum gives you access to a meaningful range of instruments and leverage options.

Each of the six cost dimensions gets a raw score from 1.0 to 5.0. But not all dimensions carry equal weight in the final rating. Here's how we think about it.

Weighting by Impact on the Average Beginner

Spreads and commissions are the costs you face on every single trade, so they carry the most weight in our trading cost scoring system. Inactivity fees, by contrast, only affect you if you stop trading - so they're factored in but weighted lower. The breakdown looks like this:

• Typical spreads (major pairs): 30% of total score - the most frequent and direct cost
• Commission structure: 20% - significant, especially for active traders
• Overnight financing rates: 20% - critical for anyone holding positions overnight
• Deposit and withdrawal fees: 15% - affects your usable capital and profit extraction
• Inactivity fees: 10% - relevant but situational
• Account minimum requirements: 5% - scored separately as an accessibility metric

How the Final Rating Is Calculated

Each dimension score is multiplied by its weight, then summed for a weighted total out of 5.0. A broker scoring 4.8 on spreads but 2.0 on withdrawal fees won't end up with a top overall rating - the withdrawal fee penalty drags the final number down, as it should.

What you'll notice is that our ratings tend to cluster between 4.0 and 4.6 for established, regulated brokers. A score below 4.0 typically indicates a specific problem area - unusual fees, wide spreads, or a history of user-reported withdrawal issues. We don't inflate scores to make partners look better than they are.

Accessibility Score: A Separate Metric

Minimum deposit requirements are scored on a separate 'accessibility' scale that doesn't fold directly into the cost score. A broker with a $20 minimum deposit scores higher on accessibility than one requiring $250, all else being equal. This matters for our audience - if you're just getting started, the ability to open a real account with $50 or less is genuinely useful.

Here's something most comparison sites won't say plainly: we earn commissions when you click through to a broker and open an account. That's the affiliate relationship, and we're not going to hide it in a footer.

What we can tell you is how we prevent that relationship from distorting our ratings. The people who set our scores are separate from the people who manage broker partnerships. A broker cannot pay to improve its score, request removal of a negative finding, or buy a higher placement in our ranked lists. If a broker we partner with has a genuinely poor fee structure, that shows up in the score.

What 'Pay-to-Rank' Would Look Like (And Why We Don't Do It)

Pay-to-rank is when a broker pays a flat fee to appear at the top of a comparison list regardless of merit. You'll find this practice across a lot of financial comparison sites - the broker in position one isn't there because it's the best option for you. It's there because it paid the most. Our rankings are determined entirely by our weighted cost scores. Full stop.

How to Verify Our Independence

Check whether our top-ranked broker on any given list is also the highest-rated by score. If a broker is ranked first but has a lower score than the broker ranked second, that's a red flag on any site. On DemoTradingPlatforms, ranking position and score should align. If you ever spot a discrepancy, we want to hear about it.

One more thing: we recommend consulting a local tax professional before trading, since tax treatment of trading profits varies significantly by jurisdiction. In some countries, gains are taxed as capital gains; in others, as income. In places like the UAE, trading profits may be tax-free. We don't give tax advice, and neither should your broker.

Applying our transparent broker comparison methodology to the brokers currently featured on DemoTradingPlatforms produces the ratings below. These scores reflect cost data collected and verified in Q2 2026.

A few things stand out when you look at the results. eToro scores well on accessibility (minimum deposit of $50) and has a clear, spread-based fee structure, though its overnight financing rates on CFDs (contracts for difference, where you're trading price movements without owning the underlying asset) are on the higher side. Libertex uses a commission-per-trade model rather than spreads, which is unusually transparent and scores well in our commission structure dimension. Capital Com stands out for its very low $20 card deposit minimum, making it one of the most accessible options for beginners globally.

IC Markets is a strong performer on raw spread costs, particularly on its ECN (Electronic Communication Network) account type, where EUR/USD spreads regularly come in under 0.1 pips during peak hours. The trade-off is a commission charge of around $7 per standard lot round-turn, which is competitive but means it's less cost-efficient for very small trade sizes.

XTB and Plus500 both score 4.2 overall. XTB's fee structure is straightforward and its inactivity fee policy is clearly disclosed (a €10/month charge after 12 months of no trading). Plus500 operates on a spread-only model with no commissions, but its spreads on some instruments are wider than competitors, which is reflected in its spread score.

FxPro offers multiple account types with different cost structures, which adds flexibility but also complexity. For a beginner, the additional choices can be confusing - that's a minor negative in our accessibility scoring, though the underlying costs on its standard account are competitive.

• eToro - Overall rating: 4.5 | Min. deposit: $50
• Libertex - Overall rating: 4.4 | Min. deposit: $100
• Capital Com - Overall rating: 4.4 | Min. deposit: $20 (card)
• IC Markets - Overall rating: 4.3 | Min. deposit: not publicly specified
• XTB - Overall rating: 4.2 | Min. deposit: not publicly specified
• Plus500 - Overall rating: 4.2 | Min. deposit: $100
• FxPro - Overall rating: 4.2 | Min. deposit: $100
