Daily average revenue trades, the brokerage activity metric.

Estimates for planning only, not financial advice.
DART rate means daily average revenue trades: total revenue-generating trades divided by the number of trading days in the period. Brokerages like Charles Schwab and Interactive Brokers report DARTs every quarter as the headline measure of client trading activity. A DART of 3,889 means the firm averaged 3,889 commissionable trades on each trading day.
How to Use This Calculator
Enter the total number of revenue trades for the period and the number of trading days it covers. A full US year has about 252 trading days; a quarter has roughly 63. The calculator divides the first number by the second and also annualizes the pace to weekly and monthly run rates.
Add up every revenue-generating trade in the period. Revenue trades are trades that produce commission or payment for order flow, not free trades or transfers.
Enter the trading days in the period. Use 252 for a full year, 63 for a quarter, or count the actual market-open days.
Read your DART figure plus the weekly and monthly run rates, which make it easy to compare quarters of different lengths.
The DART Formula
The math is deliberately simple so the number is comparable across firms and quarters. What varies is the definition of a "revenue trade": most brokers count each commissionable order execution, and some include trades that generate payment for order flow. Because definitions differ slightly, DART comparisons are most honest between similar business models, such as two discount brokers, rather than between a discount broker and a full-service wealth manager.
Worked Example
A brokerage reports 980,000 revenue trades for the year. With 252 trading days, DART = 980,000 / 252 = 3,888.89. That is about 19,444 trades per week and 81,667 per month. If the prior year showed 3,100 DARTs, activity grew roughly 25 percent, which usually foreshadows higher transaction revenue in the earnings report. Analysts watch this number because trading revenue moves with it almost mechanically.
Reading Your DART Result
DART has no universal good or bad value; it is a scale metric. A startup broker might celebrate 5,000 DARTs while a giant reports millions. What matters is the trend and the revenue per DART. Rising DARTs with flat revenue per trade can signal a shift toward low-margin order flow, while flat DARTs with rising revenue per trade suggest better monetization of the same activity.
| What you compare | Why it matters |
|---|---|
| DART vs prior quarter | Shows whether client activity is accelerating or cooling |
| DART vs competitors | Reveals market share shifts in active trading |
| Revenue per DART | Shows monetization quality behind the activity |
| DART vs market volatility | Volatile markets usually lift DARTs; calm markets shrink them |
Common Mistakes
The classic error is dividing by calendar days instead of trading days, which understates DART by about 30 percent. Another is mixing revenue trades with total trades; transfers, ACATS moves, and free trades inflate the count without adding revenue. If you are sizing up a brokerage stock, pair DART with our earnings per share calculator thinking: activity is the top of the funnel, but only monetized activity reaches the bottom line. For valuing the business behind the metric, run a discounted cash flow valuation rather than pricing the DART number itself.
How Analysts Use DARTs Around Earnings
Analysts treat DARTs as a leading indicator for brokerage earnings. Because transaction revenue follows trading activity with a short lag, a quarter with sharply higher DARTs usually prints higher revenue even before the earnings release confirms it. The cleaner trade is comparing DART growth to revenue-per-DART: if DARTs rose 25 percent but transaction revenue rose only 10 percent, monetization slipped, perhaps because the mix shifted toward options or payment-for-order-flow trades. That mix shift matters more than the headline count.
Seasonality also deserves attention. The first quarter is usually the busiest for retail trading, summer the quietest. Comparing Q3 DARTs to Q1 DARTs and calling it a decline is a rookie error; compare each quarter to the same quarter last year. Also strip out one-off events: a meme-stock frenzy or a market crash can double DARTs for a month without telling you anything durable about the franchise. The trend across four to eight quarters is the signal; any single quarter is mostly noise.
What DARTs Miss
DARTs say nothing about account growth, asset flows, or revenue mix, and a broker can look healthy on DARTs while the franchise quietly erodes. A firm growing DARTs 20 percent while net new accounts fall is squeezing more trades from a shrinking base, which eventually runs out. Likewise, DARTs ignore the shift from commissions to asset-based fees: a broker converting traders into advisory clients may show flat DARTs while revenue per client climbs. Read DARTs alongside net new assets and client growth, never alone. A brokerage growing all three together has a genuinely healthy franchise; strength in only one is a story that needs a second chapter.

Frequently Asked Questions
What does DART stand for in finance?
DART stands for daily average revenue trades. It is the standard activity metric reported by online brokerages, equal to total revenue-generating trades divided by trading days in the period. Firms like Schwab and Interactive Brokers disclose it quarterly.
How do you calculate DARTs?
Divide total revenue trades by the number of trading days. For example, 245,000 revenue trades over a 63-day quarter gives 3,889 DARTs. Use market-open days only, not calendar days, or the figure comes out roughly 30 percent too low.
What counts as a revenue trade?
Any trade execution that generates revenue for the broker, through commissions, spreads, or payment for order flow. Account transfers, ACATS moves, journal entries, and genuinely free trades do not count. Definitions vary slightly by firm, so cross-broker comparisons deserve a footnote.
How many trading days are in a year?
About 252. The US market is open roughly 252 days a year after weekends and market holidays are removed. A quarter runs about 63 trading days and a month about 21. This calculator annualizes from whatever period you enter.
Is a higher DART always better for a brokerage?
Not always. Higher DARTs mean more activity, but revenue per trade matters just as much. A broker can grow DARTs while revenue per trade falls if the mix shifts toward payment-for-order-flow trades. Check both numbers together.
Why do DARTs spike in volatile markets?
Volatility creates both fear and opportunity, so clients trade more: rebalancing, hedging, and reacting to headlines. DARTs typically surge during market selloffs and earnings seasons, then fade when markets go quiet. It is a sentiment gauge as much as a business metric.
Do DARTs include options and futures trades?
Usually yes, when they generate revenue. Most brokers count each executed order across stocks, options, and futures in the revenue-trade total. Check the specific firmβs definition in its earnings release, since counting conventions differ.
Can I use DART to compare two brokers?
Roughly. DART comparisons work best between similar models, like two discount brokers. A full-service wealth manager will show far fewer DARTs per client dollar because its revenue comes from advisory fees, not trades. Compare like with like.
What is the difference between DARTs and total accounts?
DARTs measure activity while accounts measure scale. A broker can add a million dormant accounts without moving DARTs at all. Growth investors watch both: accounts for reach, DARTs for engagement.
Where do brokers publish their DART numbers?
In quarterly earnings releases and monthly activity reports. Most large brokers post a monthly metrics update with DARTs, new accounts, and client assets. Those releases are the primary source analysts use to track the trend.
