Calculate trailing twelve months totals from the latest four quarterly figures for revenue, earnings, EBITDA, or other monetary metrics.
Last updated
Rolling last four quarters, not a calendar year Use this TTM calculator to roll forward revenue, earnings, EBITDA, or another monetary metric from the latest four reported quarters. It shows the rolling total and average quarter so you can compare the current run-rate with older annual figures.

What TTM leaves out
This tool adds the latest four quarters only. It does not rebuild TTM from year-to-date figures, adjust for one-time items, or replace the company filing that supplied the underlying numbers.

Trailing twelve months calculator guide: rolling totals, LTM comparisons, and TTM revenue
A trailing twelve months calculator rolls the latest four reported quarters into a single total so you can compare revenue, earnings, EBITDA, or other repeating monetary metrics on a current run-rate basis. It is often called TTM or LTM and is useful when calendar-year totals lag behind the newest quarter.
What trailing twelve months means
Trailing twelve months, usually shortened to TTM or LTM, means the most recent four consecutive quarters added together as one rolling twelve-month period. The reference window moves each time a new quarter is reported, so the total always reflects the latest available run-rate instead of a fixed calendar year.
That rolling view is helpful when seasonality, fiscal-year timing, or a recent earnings release makes a simple year-to-date total harder to interpret. It lets you compare the newest quarter set with an annual result without waiting for the fiscal year to close.
How this calculator works
The calculator adds the four quarterly figures you enter and divides that sum by four to show the average quarter as well. The result is a compact current-period snapshot that works for revenue, earnings, EBITDA, free cash flow, or similar monetary metrics that can be summed across quarters.
Because the inputs are quarterly amounts, the calculator is best used with the latest four reported quarters. If you only have year-to-date data, you need a bridge from the prior-year quarter before you can rebuild a proper trailing twelve months figure.
TTM total = Q1 + Q2 + Q3 + Q4
Adds the latest four reported quarterly figures into one rolling twelve-month total.
Quarterly average = TTM total ÷ 4
Shows the average quarter inside the same trailing twelve months window.
When to use TTM revenue, TTM earnings, and TTM EBITDA
TTM revenue is the cleanest fit when you want a current sales run-rate that is still grounded in reported numbers. TTM earnings is useful when you need a recent profit snapshot for valuation or internal analysis, while TTM EBITDA is often used when comparing operating performance before capital structure and tax effects.
These measures all answer slightly different questions, but they share the same rolling window. The key is to keep the metric definition consistent so you do not compare one company’s trailing revenue with another company’s forward estimate or a different earnings basis.
Use TTM revenue to compare the latest run-rate with older annual totals.
Use TTM earnings when you want a recent profit figure for valuation work.
Use TTM EBITDA when you want a current operating-profit proxy that still rolls with the latest quarter.
Suppose the four most recent quarters are 25,000, 28,000, 30,000, and 32,000. The trailing twelve months total is 115,000 and the quarterly average is 28,750. That gives you a simple rolling baseline that is easier to compare with a prior annual result or a peer company’s recent run-rate.
The same structure works if the metric is earnings, EBITDA, or another monetary figure. The arithmetic is the same; only the label and the interpretation change.
TTM vs YTD, annual totals, and NTM estimates
Year-to-date figures start at the beginning of the current fiscal year, while TTM starts twelve months back and always looks at the latest four quarters. Annual totals are fixed to the fiscal year, so they can lag behind the newest quarter when you need a current snapshot.
NTM, or next twelve months, is different again because it is a forward-looking estimate built from forecasts. TTM is historical and based on reported numbers, which is why it is often preferred when a valuation multiple or operating ratio needs a current but verifiable base.
TTM is historical and rolling.
YTD is cumulative from the fiscal-year start.
NTM is forecast-based and forward-looking.
What this estimate excludes
This calculator does not reconstruct a TTM figure from year-to-date statements, adjust for one-off items, normalize accounting changes, or convert between currencies. It also does not decide whether a given metric should be treated as revenue, earnings, or another reporting label.
Use the result as a quick comparison point, then confirm the underlying figures in the company filing, investor deck, or reporting package before relying on them for a presentation, valuation model, or published analysis.
Frequently asked questions
What does TTM stand for?
TTM stands for trailing twelve months. It refers to the most recent four quarters added together as one rolling twelve-month period.
Is TTM the same as LTM?
In most finance contexts, yes. LTM means last twelve months and is usually used interchangeably with TTM, which means trailing twelve months.
How do I calculate TTM from quarterly figures?
Add the latest four quarterly values together. If you want the average quarter as well, divide that total by four.
Can I use this calculator for earnings or EBITDA?
Yes, as long as the values are the same kind of monetary quarterly metric across all four inputs. The calculator is not limited to revenue.
What if one quarter is negative?
That is fine for metrics such as earnings. A negative quarter simply reduces the rolling total, which can be exactly what you want when the business had a loss period.
Does TTM smooth seasonality?
It helps, because it averages across four quarters instead of showing only one period. It does not eliminate seasonality completely, but it gives a less noisy view than a single quarter alone.
When should I use TTM instead of YTD?
Use TTM when you want a rolling twelve-month snapshot that includes the latest quarter. Use YTD when you specifically want results from the start of the current fiscal year.
When should I use TTM instead of NTM?
Use TTM for reported historical numbers and NTM for forecasts. TTM is based on actual results, while NTM is based on expected future performance.
Can I rebuild TTM from year-to-date figures?
Yes, but not from YTD alone. You usually need the prior-year quarter as a bridge so you can replace the old quarter with the latest reported quarter and rebuild the trailing twelve months total.
