# TTM and YoY

TTM and YoY are shorthands used in fundamental filters and [screener](/glossary/screener) [results columns](/glossary/fundamental-metric-columns). **TTM (trailing twelve months)** sums the last four reported quarters into a rolling one-year figure ending at the most recent report, not at a fiscal year-end. **YoY (year over year)** compares a figure to the same figure one year earlier, cancelling out seasonal ups and downs.

**Also seen as:** LTM

## How does Fincanva handle it?

- On a screener's **Fundamentals** tab, the small second line under a column header states the measurement basis: **Sales** reads TTM; **Sales growth**, **Gross profit growth**, **EBITDA growth**, **Net income growth** and **FCF growth** read TTM · YoY; **Working capital growth** reads YoY alone.
- Hovering any of those seven headers shows this term's explanation.
- The six growth columns are tinted by the sign of the change; **Sales** is a level, so it is not.

## How is a year-over-year change calculated?

A year-over-year change is the current figure divided by the figure one year earlier, minus one — the same as the difference between the two, divided by the earlier figure.

$$
\text{YoY} = \frac{{V_{t}}}{{V_{t-1\text{yr}}}} - 1
$$

where:

- the current value — for the TTM · YoY columns, the latest TTM figure
- the same value one year earlier

## Why are TTM and YoY used?

TTM gives an up-to-date annual figure between fiscal year-ends: instead of waiting for the full-year accounts, it adds the four most recent quarters, so the number moves every reporting season. YoY strips out seasonality: comparing this quarter to the same quarter last year avoids the distortion of holding a holiday quarter against a summer one.

## What does it look like in practice?

Suppose a company's fiscal year ends in December. After it reports Q3, its **fiscal-year revenue** still shows last December's full-year total — up to nine months stale. Its **TTM revenue** instead sums Q4 of last year plus Q1, Q2, and Q3 of this year, giving a rolling twelve-month total that already reflects the most recent quarter. If that TTM figure is 8% above the TTM a year earlier, its revenue **YoY** is +8%.
