TTM Calculator (Trailing Twelve Months)
Print| Average Quarterly Figure | $0.00 |
When evaluating a company’s financial performance, relying solely on static annual reports (10-K) leaves you with outdated information, while analyzing individual quarterly reports (10-Q) introduces heavy seasonal distortion. To get an accurate, up-to-date picture of financial health, equity analysts and investors turn to Trailing Twelve Months (TTM) metrics.
Our free TTM Calculator calculates continuous 12-month totals for revenue, EBITDA, net income, or cash flows by combining the most recent quarterly reports with prior full-year financial data.
How to Calculate Trailing Twelve Months (TTM)
There are two primary methods to compute TTM metrics depending on how financial statements are published.
Method 1: Sum of the Most Recent 4 Quarters
TTM = Q_most_recent + Q_prior_1 + Q_prior_2 + Q_prior_3
Method 2: Year-to-Date (YTD) Formula (Using Most Recent 10-Q and 10-K)
TTM = Most Recent YTD Metric + Full Prior Year Metric - Prior Year Same-Period YTD Metric
Step-by-Step TTM Calculation Example
Imagine a company that is currently in Q3 of 2026. You want to calculate its TTM revenue using its four most recent quarterly 10-Q earnings reports:
- Q4 2025 Revenue: $320,000
- Q1 2026 Revenue: $250,000
- Q2 2026 Revenue: $300,000
- Q3 2026 Revenue: $280,000
Let’s sum the four consecutive quarters:
TTM Revenue = $320,000 + $250,000 + $300,000 + $280,000 = $1,150,000
| Quarter Period | Reported Revenue | TTM Status |
|---|---|---|
| Q4 2025 | $320,000 | Included (Quarter 1 of 4) |
| Q1 2026 | $250,000 | Included (Quarter 2 of 4) |
| Q2 2026 | $300,000 | Included (Quarter 3 of 4) |
| Q3 2026 | $280,000 | Included (Quarter 4 of 4) |
| Total TTM Revenue | $1,150,000 | Continuous 12-Month Total |
Frequently Asked Questions (FAQ)
What does TTM mean in finance?
TTM stands for Trailing Twelve Months. It refers to the financial data from the immediately preceding 12 consecutive months, offering a modernized evaluation of performance without waiting for an annual fiscal report.
Why is TTM preferred over annual or quarterly metrics?
TTM smooths out short-term quarterly spikes, accounts for annual seasonality (such as holiday sales boosts), and provides a much more timely valuation than last year’s audited annual 10-K report.
How does TTM affect price-to-earnings (P/E) ratios?
The TTM P/E Ratio divides a stock’s current price by its net earnings over the past 12 months. This contrasts with Forward P/E (which uses projected future earnings) and Trailing P/E (which might use past fiscal year data).
