Key takeaways
- TTM covers the past 12 consecutive months of financial data, and it's also known as LTM (last twelve months)
- It gives you a current, seasonally smoothed view of performance instead of relying on a stale fiscal-year figure
- Lenders, investors and business owners use it to assess financing and to plan ahead
- A common formula is: latest full fiscal year + current year-to-date − prior-year year-to-date
What does TTM mean?
TTM means trailing twelve months, the past 12 months of consecutive financial or performance data for a business. It's also called LTM, or last twelve months.
Rather than waiting for a full accounting period to close, TTM gives you a rolling snapshot that you can refresh as each new month finishes.
TTM vs YTD and LTM
YTD and LTM often come up alongside TTM, so it helps to know how they compare. TTM always spans a full 12 months, while year-to-date (YTD) runs from the start of the current fiscal year up to today, so it can cover less than 12 months. LTM, or last twelve months, is simply another name for TTM.
Why is TTM used?
TTM keeps your numbers current and easy to compare. Business owners, lenders and investors rely on it for a few reasons:
- Removes stale fiscal-year data that no longer reflects current trading
- Smooths out seasonal peaks and one-off swings for a truer picture
- Gives a rolling 12-month view that you can update every month
How is TTM used?
Once you have a TTM figure, you can put it to work across everyday decisions and formal reviews. Lenders and investors often ask for it, and you can rely on it yourself when you review financial reports for planning and performance tracking. Common uses include:
- Show lenders and investors a current picture when you apply for financing
- Support business planning and budgeting decisions
- Track trends and growth over a consistent 12-month window
- Compare your performance against competitors
- Monitor key performance indicators (KPIs) and net profit over time
Where do you find TTM data?
You can pull TTM figures from the reports you already run, like your cash flow statement and balance sheet. Some figures you might track on a TTM basis include:
- TTM revenue
- TTM cash flow
- TTM accounts receivable turnover ratio
How do you calculate TTM?
You can work out TTM in a few ways, depending on the data you have to hand. The simplest is to add up the most recent 12 months of data, or you can total your last four complete quarters. When a fiscal year has already closed, use this formula:
TTM = latest full fiscal year + current year-to-date − prior-year year-to-date
For example, if a business earned S$500,000 in its last fiscal year, S$150,000 so far this year and S$120,000 in the same period last year, its TTM revenue is S$530,000.
