Also known as: Client Retention Rate, Client Retention Percentage, Loyalty Rate
Retention rate is the percentage of clients who stay active and keep trading with a broker or IB over a defined period. It is the direct mathematical inverse of churn rate: if 30 percent of clients leave, the retention rate is 70 percent.
The standard formula isolates the clients you kept from the ones you newly acquired, so growth doesn't flatter the number: take the clients at the end of the period, subtract new clients gained during it, divide by the clients you started with, and multiply by 100. Getting this right matters, because counting new sign-ups as "retained" is the most common way partners fool themselves into thinking a leaky book is healthy.
Retention rate is the single clearest read on business quality for a partner. A high, stable rate means the traders you acquire stick around long enough to repay their acquisition cost and then some, which is exactly the condition under which it becomes safe to scale paid advertising. A low rate means you are pouring new leads into a bucket that empties faster than you can fill it.
For example, an IB starts the year with 500 active traders, acquires 100 new ones, and finishes with 450 active. The calculation is (450 − 100) / 500 × 100 = 70 percent: they kept 350 of the original 500. In the high-risk retail forex space, holding 40 to 50 percent of clients actively trading beyond their first 90 days is considered a strong result.
Retention rate is calculated over a fixed window — weekly, monthly, quarterly, or annual — and its value depends entirely on how you define "active." A partner might count a client as retained only if they placed at least one trade in the period, or funded, or logged in; each definition yields a different number, so consistency matters more than the absolute figure. The clean formula subtracts new acquisitions so that fresh sign-ups never inflate the result.
In practice partners track retention rate as a trend and pair it with cohort analysis, grouping clients by the month they joined and watching what share of each cohort survives 30, 60, and 90 days. That reveals whether onboarding changes actually move the needle. Retention rate also feeds directly into lifetime value: a higher rate lengthens the average client lifespan, which multiplies expected revenue per acquired trader and reshapes how much a partner can profitably bid for a lead.
Choose the window (for example a quarter) and define what 'active' means — traded, funded, or logged in — then apply it consistently.
Record active clients at the start, active clients at the end, and how many new clients you acquired during the window.
Compute ((End − New) / Start) × 100 so newly acquired clients don't inflate the retained figure.
Group clients by join month and track 30/60/90-day survival to see whether onboarding and retention changes are working.
Use the trend to set how aggressively you can scale acquisition spend, since higher retention lengthens client lifespan and lifts lifetime value.
Why it matters for partnership: Retention rate is the clearest signal of a healthy, profitable partner book. A high, stable rate is what makes scaling ad spend safe, because acquired traders stay long enough to repay their cost and compound into rebate income rather than leaking away.
An IB begins the year with 500 active traders, acquires 100 new ones, and ends with 450 active. The retention rate is (450 − 100) / 500 × 100 = 70%, meaning 350 of the original 500 stayed. That single number tells the IB it is safe to reinvest in acquisition, because most acquired traders survive long enough to repay their cost.
| Aspect | Retention Rate | Churn Rate |
|---|---|---|
| Measures | Clients kept | Clients lost |
| Direction | Higher is better | Lower is better |
| Relationship | 100% − churn | 100% − retention |
| Signals | Book health, LTV upside | Leakage, acquisition waste |
Invest relentlessly in the first-week onboarding experience — cohort data consistently shows strong early engagement lifts long-term retention, which is the cheapest lever you control.
Watching raw registration counts in the IB portal while ignoring retention rate creates a false sense of growth; you can add sign-ups every month and still shrink if churn outruns acquisition.
Keeping 40-50% of retail clients actively trading beyond their first 90 days is considered strong in the high-risk forex industry. Rates vary by client quality, onboarding, and how you define 'active'.
Use ((Clients at End − New Clients Acquired) / Clients at Start) × 100. Subtracting new clients ensures fresh acquisitions don't inflate the figure and hide churn.
They are two sides of the same coin: retention rate plus churn rate equals 100%. If your churn is 40%, your retention rate is 60%.
Sign-ups measure only the top of the funnel. Retention measures whether those clients stay long enough to repay their acquisition cost, which is what actually determines profit and safe ad spend.
Higher retention lengthens the average client lifespan, which multiplies expected revenue per acquired trader. A small retention gain can raise LTV substantially and change how much you can profitably bid for leads.
Track it on a consistent cadence — monthly or quarterly — and pair it with cohort analysis. The trend over time is far more useful than any single snapshot.
