Sonix charges roughly $10 per hour of audio on its pay-as-you-go Standard tier, and about $5 per hour on the Premium subscription (as listed on its current pricing page). The full bill depends on plan, add-ons like translation, and whether you actually use the minutes you're paying for.
If you transcribe a couple of hours a month, pay-as-you-go is fine. Cross roughly 5 hours a month and Premium starts winning. Past 30 hours, you're better off on Enterprise or a per-minute API.
- Standard: pay-as-you-go, $10/hour of audio, no monthly fee.
- Premium: subscription ($22/month or $264/year), $5/hour of audio.
- Enterprise: custom pricing, usually for teams using 100+ hours/month.
- Add-ons: translation, advanced exports, and team features cost extra.
- Hidden cost: subscription minutes don't roll over, so paying for hours you won't use is a real risk.
How much does Sonix actually cost per hour?
Sonix's headline is "from $5 per hour," but that's the Premium subscription rate. The honest picture:
| Plan | Audio rate | Monthly fee | Best for |
|---|---|---|---|
| Standard (PAYG) | $10/hr | $0 | 1-5 hours/month |
| Premium | $5/hr | $22/mo | 5-30 hours/month |
| Enterprise | Custom | Custom | Teams over 100 hours/month |
On a one-hour interview, Standard costs about $10. On 20 hours a month, Premium works out to roughly $122 all-in vs $200 on Standard.
For broader context across the market, our breakdown of real AI transcription costs walks through how per-minute vs subscription pricing compares across the major services.
What's actually included on each plan?
Standard gets you transcription in 50+ languages, basic exports (Word, PDF, SRT, VTT), speaker labels, and the in-browser editor. That covers what most people need on a single file.
Premium adds:
- A monthly translation allowance (extra translation billed on top)
- Advanced export formats and customization
- Multi-user account features
- Priority email support
Enterprise layers on SSO, dedicated success, custom contracts, and security review. If you don't need those, Premium is the realistic ceiling.
What quietly drives the cost above the headline?
A few things inflate the bill in ways the pricing page doesn't make obvious:
- Translation isn't transcription. Sonix bills translation separately. If you're working with multilingual content, plan for it as a second line item.
- Subscription minutes expire. Premium's value depends on actually using the audio time. If you only transcribe 3 hours into a month you've paid for 30, your effective per-hour cost balloons.
- Re-runs cost again. Re-transcribe a file with a different model or after heavy edits, and the audio time bills again. A scrappy first pass on long files adds up.
- Long files. Sonix is fast, but 4-hour conference recordings at $10/hr aren't trivial.
How accurate is Sonix for the price?
Sonix's accuracy is roughly in line with other top AI services. Expect somewhere in the 85-95% word-accuracy range depending on audio quality, with lower numbers on multi-speaker or accented content. Sonix doesn't publish official WER benchmarks, so anyone quoting an exact number is guessing.
Our guide to what real-world transcription accuracy looks like goes into the numbers. Short version: source audio quality matters more than which top-tier service you pick.
Is Sonix worth it for your use case?
- Polished web editor with strong speaker labeling
- Wide language coverage
- Good fit for teams that need collaboration and translation
- High per-hour rate compared with Whisper-based options
- Subscription only pays off above ~5 hours/month
- Translation, exports, and re-runs add up faster than expected
Pick Sonix if you want a polished web editor, you'll genuinely use 5-30 hours/month, and translation or team features matter to your workflow.
Skip Sonix if you're an occasional user (the per-hour rate is high), you mainly need a clean transcript without the editor, or you're cost-sensitive on long files.
Sonix alternatives, ranked by price
| Service | Typical price | Trade-off |
|---|---|---|
| Whisper (self-hosted) | ~$0 + your time | Free if you have a GPU; setup required |
| OpenAI Whisper API | $0.006/min (~$0.36/hr) | Cheap, no UI, build it yourself |
| VTS | Pay-per-job, no subscription | Web transcribe, no monthly commitment |
| Otter Pro | ~$8.33/mo + minute caps | Cheaper if you stay in-app |
| Rev (AI) | $0.25/min (~$15/hr) | More expensive than Sonix |
| Rev (Human) | $1.50/min (~$90/hr) | Human accuracy, premium price |
If you don't need an editor and just need a clean transcript, you can transcribe a file directly without committing to a monthly plan.
For a tool-by-tool comparison of these options, our honest look at the major transcription services does the side-by-side.
When does the Premium subscription pay off?
Run the math: Premium becomes cheaper than Standard around 4.5 hours/month of audio. Below that, you're paying for capacity you won't touch. Above 30 hours/month, you'll likely outgrow Premium's value and want Enterprise or a per-minute API instead.
The subscription trap is real. Most people overestimate how much audio they'll actually transcribe. Track a couple of months of real usage before locking in for a year.

Sonix pricing FAQ
Does Sonix offer a free trial?
Yes. 30 minutes of free transcription on signup, no credit card required. Enough to test accuracy on a real file from your own workflow before paying anything.
Is Sonix cheaper than Rev?
Sonix at $5-10/hour is cheaper than Rev's AI tier (~$15/hour) and far cheaper than Rev's human service (~$90/hour). Rev's human transcription is more accurate, but for AI-only work Sonix wins on price.
Can I pay per minute instead of per hour?
Sonix bills by the second internally, but the listed rate is per hour of audio. There's no separate per-minute tier in the public pricing.
Are there hidden fees?
Translation, premium exports, and re-transcription all cost extra. Subscription minutes expire monthly. Check what your actual usage looks like before committing to Premium.
