Duolingo has published its annual report for the year ending December 31, 2024 (Look for a 10-K file if you are seeking the below numbers).
Revenue from the Duolingo English Test increased by about 10.7 percent in 2024 to a total of $45,640,000. This suggests that test volumes in 2024 were about the same as in 2023.
Below are quarter-by-quarter revenues for 2024. Following each revenue figure is a crude estimate (see below for an explanation) of how many times the test was taken in that quarter.
Note that the test cost $59 from January 1 to April 15. For the rest of the year, it cost $65.
- Q4: $11,415,000 (175,615)
- Q3: $10,772,000 (165,723)
- Q2: $10,698,000 (164,584)
- Q1: $12,755,000 (217,000)
My crude estimates are derived by dividing revenue by the cost of taking the test. This a VERY rough estimate – some people pay an additional fee to get faster results, while others get a discount by purchasing two tests at a time. Others pay nothing at all thanks to the Duolingo Access program. And if you pay for the test and don’t show up… Duo keeps your money. Note also that the Q2 estimate assumes a price of $65 for the whole quarter, though the price was actually a bit cheaper for the first 15 days.
With that out of the way: we can guess there were about 722,922 administrations of the DET in 2024.

Here are the quarterly revenues and estimates for 2023. The test cost $49 from January 1 to April 5. For the rest of the year it cost $59.
- Q4 2023 – $10,819,000 (183,372)
- Q3 2023 – $10,600,000 (179,661)
- Q2 2023 – $9,800,000 (166,101)
- Q1 2023 – $9,970,000 (203,469)
From this we can guess there were about 732,603 administrations in 2023. Again, though, take that figure with a grain of salt.
