Key takeaways
- TTM stands for trailing twelve months, the most recent 12 consecutive months of financial or performance data for a business.
- TTM gives a current view of performance because it replaces outdated fiscal-year numbers and smooths out seasonal ups and downs.
- Lenders, investors, and business owners use TTM to assess a business without waiting for the next fiscal reporting period to end.
- You calculate TTM by adding the latest full fiscal year to the current year-to-date figure, then subtracting the prior-year figure for the same period.
What does TTM mean?
TTM means trailing twelve months. It's the past 12 consecutive months of financial or performance data for a business.
Another name for TTM is last twelve months (LTM), so you can treat the two terms as the same thing. TTM looks at your most recent data rather than the last completed fiscal year.
TTM differs from year-to-date (YTD), which covers the period from the start of the current fiscal year to today. YTD can be shorter than 12 months, while TTM is always a full 12 months.
Why is TTM used?
TTM is a helpful way to look at the financials of a small business because it removes the problem of using outdated fiscal numbers. Without a TTM calculation, the data from your most recent fiscal year could be nearly a year out of date. TTM uses the latest 12-month period to give more accurate numbers for the current state of the business.
TTM also smooths out the ups and downs that come with seasonal data or one-off changes. For example, a business might earn higher revenue over a peak season, or a single event might push revenue down for a quarter. TTM gives you a longer view of performance while keeping your financials current and adjusted for seasonal variation.
How is TTM used?
Small businesses use TTM to give lenders and investors accurate, up-to-date financial figures. External parties can then assess the business over the past 12 consecutive months without waiting for the next fiscal reporting period to close.
TTM also supports ongoing business planning, spotting internal trends, monitoring growth, and comparing your business to competitors. You can use it to show how close you are to meeting key performance indicators (KPIs) across the trailing 12-month period.
The figures you need for TTM come from the reports you already keep in your financial accounting. Balance sheets, profit and loss (P&L) statements, cash flow statements, and other financial reports supply the source data.
Where do you find TTM data?
You'll find TTM data across your standard financial reports, and you can pull several useful figures from them. Common TTM measures include:
- TTM revenue: the total revenue earned over the trailing 12 months
- TTM cash flow: the money moving in and out of the business over the trailing 12 months
- TTM accounts receivable turnover ratio: the number of times an accounts receivable balance is collected over the trailing 12 months
How do you calculate TTM?
There are a few ways to calculate TTM, and they all cover the same 12-month window. You can take the most recent 12 complete months, or add up the last four complete quarters.
A third method uses figures you already report, which is handy when your last fiscal year has closed but the current year is still running. The formula is:
- TTM = latest full fiscal year + current year-to-date − prior year-to-date (same period)
Say your last fiscal year revenue was RM500,000, your current YTD revenue is RM180,000, and your prior-year YTD revenue for the same months was RM150,000. Your TTM revenue is RM500,000 + RM180,000 − RM150,000 = RM530,000. That single figure reflects the most recent 12 months of trading rather than a stale full-year total.
