A Forex broker with 300 IBs cannot treat them all the same. Some bring 50 active traders who generate consistent volume month after month. Others bring 200 registrations that never fund an account. The difference between a profitable IB program and a margin-draining one comes down to measuring the right KPIs and acting on them -- not just tracking lots traded, but understanding the full picture of IB quality, retention, and cost efficiency.
Core IB Performance Metrics
Forex IB KPIs fall into four categories: acquisition metrics (how many traders the IB brings), activity metrics (how much those traders trade), quality metrics (how valuable the trading activity is to the broker), and cost metrics (how much the broker pays per unit of value received). Tracking all four categories prevents the common mistake of rewarding IBs who generate volume without profitability.

Definition
Why It Matters
Acquisition
New funded accounts
Accounts that deposited within 30 days of registration
Measures IB ability to attract traders who actually fund
Acquisition
Registration-to-fund rate
% of registered traders who make a first deposit
Reveals traffic quality -- low rates signal incentivized or mismatched traffic
Activity
Lots per active trader
Monthly lots traded divided by active traders
Identifies whether the IB brings active traders or dormant accounts
Activity
Active trader retention
% of traders still active after 90 days
Shows whether referred traders stay or churn after the first month
Quality
Revenue per lot
Broker revenue generated per standard lot traded
Separates high-spread retail flow from low-margin scalping volume
Quality
Net deposit value
Total deposits minus withdrawals per IB
Measures actual capital the IB network brings to the broker
Cost
Cost per funded account
Total IB payouts divided by new funded accounts
Reveals acquisition cost efficiency across the IB network
Cost
Commission-to-revenue ratio
Total IB commissions divided by broker revenue from IB-referred traders
The single most important profitability metric for the IB program
The Commission-to-Revenue Ratio
The commission-to-revenue ratio is the metric that tells a broker whether their IB program is profitable. If a broker earns $8 per lot in spread revenue from IB-referred traders and pays the IB $5 per lot, the ratio is 62.5%. A healthy range for most retail Forex brokers is 40-65%. Above 65%, the broker is paying too much relative to revenue. Below 40%, the deals may be too low to retain quality IBs.
This ratio varies by account type. ECN accounts with tight raw spreads generate less revenue per lot, so the acceptable ratio shifts. Standard accounts with wider spreads can support higher IB payouts. Brokers who track this ratio at the account-type level avoid the trap of offering uniform deals that are profitable on standard accounts but margin-negative on ECN.
Calculate the commission-to-revenue ratio monthly and segment it by IB tier, account type, and instrument group. An IB who is profitable on major pairs may be cost-negative on exotic pairs where spreads are wider but lot sizes are smaller. Instrument-level analysis helps you design smarter deal structures.
Building an IB Performance Dashboard
An effective IB dashboard serves two audiences: the broker team managing the program, and the IBs themselves who need visibility into their earnings and referral performance. The broker-facing view should show aggregate KPIs, IB-by-IB comparisons, and trend lines. The IB-facing portal should show their own metrics, commission accruals, and payout history.
Broker dashboard: total lots, revenue, commission costs, top 10 IBs by volume, top 10 by profitability, flagged IBs (declining volume or negative ratio)
IB portal: personal lots generated, commission earned this period, active trader count, tier status, payout schedule and history
Alerting layer: automated alerts for IBs dropping below minimum activity thresholds, commission-to-revenue ratio spikes, or unusual trading patterns
Cohort view: compare IB cohorts by signup month to identify whether newer IBs are performing better or worse than earlier ones
Benchmarking Across the IB Network
Benchmarking requires normalizing data across IBs of different sizes. A master IB with 80 sub-IBs and 2,000 traders is not comparable to a solo IB with 15 traders on raw numbers alone. Use per-trader and per-lot metrics for fair comparison. Lots per active trader, revenue per lot, and cost per funded account are all normalized metrics that allow apples-to-apples ranking regardless of network size.
When sharing performance benchmarks with IBs, show them where they rank relative to their tier -- not the entire network. A new IB comparing themselves to a top-10 master IB is demoralizing and not actionable. Tier-relative benchmarks motivate realistic improvement.
Key Takeaways
Track IB KPIs across four categories: acquisition, activity, quality, and cost -- volume alone does not indicate IB value
The commission-to-revenue ratio is the primary profitability metric; a healthy range for retail Forex is typically 40-65%
Segment the commission-to-revenue ratio by account type and instrument to avoid margin-negative deals hiding behind aggregate averages
Build separate dashboard views for the broker team (aggregate, comparative) and IBs (personal metrics, earnings, payouts)
Use per-trader and per-lot normalized metrics for fair IB benchmarking across different network sizes
