  • TTM revenue: Total revenue earned during the most recent 12 months.
  • TTM PE ratio: Current share price divided by earnings per share over the latest 12 months.
  • TTM data: Uses rolling 12-month figures instead of fixed financial-year results.

What is trailing 12 months (TTM)?

Trailing twelve months (TTM) refers to the financial performance of a company during the most recent 12-month period. Instead of using a completed financial year, TTM uses the latest available data.

Companies release quarterly results throughout the year. TTM combines these results to create a rolling 12-month view of revenue, profit, earnings, or cash flow.

For example, if a company reports results for the quarter ending September 2026, the TTM period would cover October 2025 to September 2026.

Common TTM metrics

MetricWhat it measuresWhy it is used
TTM RevenueTotal sales in the last 12 monthsMeasures business growth
TTM EarningsProfit generated in the last 12 monthsAssesses profitability
TTM EPSEarnings per share over the last 12 monthsUsed in valuation
TTM PE RatioCurrent share price divided by TTM EPSCompares stock valuations

How do you calculate TTM revenue?

You can calculate TTM revenue using the latest four quarters of reported revenue. The process is simple and helps you use the most current financial information available.

Steps to calculate TTM revenue

  1. Collect revenue figures from the latest four reported quarters.
  2. Verify that each quarter covers a different three-month period.
  3. Add the revenue from all four quarters together.
  4. Calculate the total to determine the TTM revenue value.
  5. Compare the result with previous TTM periods to assess growth trends.

Mutual funds are subject to market risk. Please read the scheme-related documents carefully before investing.

TTM revenue calculation example

Assume a company reports the following quarterly revenue:

QuarterRevenue (Rs. crore)
Q4 2025120
Q1 2026130
Q2 2026140
Q3 2026150

TTM Revenue = 120 + 130 + 140 + 150 = Rs. 540 crore

The company's trailing twelve months revenue is Rs. 540 crore.

Analysts often compare this figure with earlier TTM periods to identify revenue growth trends.

Why TTM metrics matter to analysts and investors

TTM metrics help you evaluate a company's recent performance without waiting for the end of a financial year.

Some important benefits include:

  • Reflects the most current business performance.
  • Reduces the impact of outdated annual reports.
  • Helps compare companies consistently.
  • Supports valuation calculations such as TTM PE ratio.
  • Provides insight into revenue and earnings trends.

Investors often prefer TTM figures when market conditions change quickly because they capture more recent financial developments.

Understanding TTM PE ratio

The TTM PE ratio uses the latest 12 months of earnings rather than historical annual earnings.

Formula:

TTM PE Ratio = Current Share Price ÷ TTM Earnings Per Share (EPS)

A lower PE ratio may indicate a relatively cheaper valuation, while a higher PE ratio may suggest that investors expect stronger future growth. However, PE ratios should always be analysed alongside industry standards and company fundamentals.

TTM vs. NTM: what's the difference?

TTM and NTM are both commonly used financial metrics, but they focus on different periods.

FeatureTTMNTM
Full formTrailing Twelve MonthsNext Twelve Months
Time periodPast 12 monthsExpected next 12 months
Data sourceActual reported resultsForecast estimates
ReliabilityBased on real figuresDepends on projections
Main useHistorical performance analysisFuture growth expectations

TTM shows what has already happened, while NTM estimates what may happen in the future.

Many investors use both measures together to gain a balanced view of a company's performance and prospects.

Conclusion

Trailing twelve months (TTM) is one of the most widely used financial measures in investing and valuation. It provides a rolling 12-month view of a company's revenue, earnings, and other financial metrics.

By using the latest available financial data, TTM helps you assess current business performance more accurately than relying solely on annual reports. Whether you are analysing TTM revenue, earnings, or the TTM PE ratio, understanding this metric can improve your investment research and decision-making.
