Comparing total trading costs across brokers – what am I actually measuring and how do active traders track this?

I’m trying to move beyond just looking at spreads and actually understand my full trading cost picture across different brokers.

I know the basics – spread, commission, rebate – but I keep seeing active traders mention things like “true cost” or “net profitability” and I’m not entirely sure what they’re calculating.

For someone planning to trade 50 to 100 lots per month, what actually counts toward my total cost? Is it:

  • Just spread minus rebate?
  • Spread, commission, rebate, plus slippage?
  • Something that includes hidden fees I haven’t noticed?

And more importantly: how do experienced traders actually track and compare this across multiple brokers? Do you use a spreadsheet, special software, or just mental math?

I want to understand if the difference between AvaTrade and eToro really matters when you measure total cost, or if I’m just looking at noise.

Also – does the rebate structure from GlobeGain change how you think about broker costs, or is that just bonus money on top of your existing cost analysis?

I’m trying to get to the point where I can make a real decision based on data instead of forum opinions.

Total cost calculation for active traders needs to be precise.

Measure this: Spread (at entry and exit) + Commission + Slippage - Rebate = Net Cost Per Trade

Then multiply by your monthly lot volume. That’s your real monthly trading expense.

For 50 to 100 lots monthly on EUR/USD at AvaTrade: assume 1.8 pip average spread, no commission, 0.4 pip rebate through GlobeGain, 0.2 pip average slippage. Cost = (1.8 + 1.8 for round trip) + 0.2 - 0.4 = 3.4 pips per lot. Over 75 lots average = 255 pips cost monthly = $255 at standard lot value.

Same pair on eToro: 1.2 pip spread, no commission, 0.3 pip rebate, typically tighter execution so 0.1 pip slippage. Cost = (1.2 + 1.2) + 0.1 - 0.3 = 2.2 pips per lot. Over 75 lots = 165 pips = $165.

Difference: $90 per month. Over a year, that’s $1080. Worth tracking right.

Tools: Excel spreadsheet works fine. I use a simple formula that auto-calculates monthly totals. Some traders use dedicated trading journals – Edgewonk or similar – but that’s overkill for cost tracking.

About GlobeGain rebates: they’re real money but should be treated as separate from your broker cost analysis. Your broker cost is fixed. Rebates are the discount applied on top. Track both separately so you understand what the broker actually costs you, then see what GlobeGain saves you.

I’ve been doing active volume – 80 to 120 lots monthly – for three years. Here’s my system.

I track every single trade: entry price, exit price, spread paid, commission, slippage if any. Takes 30 seconds per trade to log. At month end, I sum everything.

Then I subtract my GlobeGain rebates that arrived that month. That shows me my net cost.

What surprised me: slippage varies way more than I expected. Some brokers slip you consistently. Others are clean most of the time. That hidden cost matters more than most traders realize.

Between AvaTrade and eToro at my volume: eToro consistently costs me about 15% less monthly when I factor everything in. Doesn’t seem huge but over a year it’s significant.

For tracking, Google Sheets works. I have columns for date, symbol, lots, entry spread, exit spread, slippage, commission, rebate per lot. Each row is one trade. Formula at bottom calculates monthly total.

Take 30 seconds per trade logging. Takes five minutes monthly to analyze. Worth every minute.

About GlobeGain: it’s not the main story. Platform execution quality (less slippage) matters more. But rebates do close the gap between expensive and cheap brokers. Combined effect of tight execution plus rebates is what moves the needle.

Tracking can get as detailed as you want. I keep it simple.

Every trade: I note the pair, lots, and whether execution felt clean. Then monthly I look at my actual account statement from the broker and my GlobeGain rebate total. Divide total cost by total lots and I get my per-lot cost.

Does it exactly match the theoretical calculation? Not always. But close enough to see which broker is actually costing less.

I don’t stress about tiny slippage differences. I focus on whether I’m consistently getting better or worse execution on one platform versus another.

The rebate question: GlobeGain is just bonus cashback. Don’t overthink it. Your real cost is what the broker charges. If GlobeGain saves you $20 monthly, that’s nice. But if the broker itself is charging you more per trade, rebates won’t fix that.

One thing I should add: different pairs have different costs. EUR/USD spreads are tight everywhere. Exotics are way wider. Make sure you’re comparing the same pairs across brokers or your analysis is useless. I made that mistake tracking GBP/JPY on one platform and EUR/USD on another – apples and oranges.

Also factor in time of day and session. Spreads are tightest during London open and New York open. Tightest between those sessions. If you only trade Asian hours or weekends, your average spread will always be wider regardless of broker. That’s not a broker quality issue, that’s a timing issue. Make sure you’re not confusing market conditions with broker performance.
