The short version

  • Each has a real cost: Amazon Translate the generous 2 million character monthly free tier applies only for a customer’s first 12 months on AWS, so translation costs step up materially in year two with no change in usage.; Microsoft Translator published free-tier detail is thinner than Google’s or Amazon’s clearly stated character allowances, making it harder to estimate cost from public documentation alone.
  • They diverge on capability: Amazon Translate covers Active Custom Translation, Microsoft Translator covers Speech translation.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Amazon Translate

  • The generous 2 million character monthly free tier applies only for a customer’s first 12 months on AWS, so translation costs step up materially in year two with no change in usage.
  • There is no consumer-facing app or website, so it is unusable for casual personal translation the way Google Translate or Microsoft Translator are.
  • Document translation of Office files costs double the standard per-character rate, which is easy to underestimate when budgeting a document-heavy project.
  • Active Custom Translation, the tool for improving output with domain-specific data, costs four times the standard rate at $60 per million characters.
  • As with all major MT APIs, output for low-resource languages and specialised terminology often still needs human review, so it does not substitute for a human translation service on customer-facing or legally sensitive content.

Microsoft Translator

  • Published free-tier detail is thinner than Google’s or Amazon’s clearly stated character allowances, making it harder to estimate cost from public documentation alone.
  • Translation quality for major language pairs is broadly comparable to Google Translate and Amazon Translate, so there is little functional differentiation beyond price and Azure ecosystem convenience.
  • Commitment-tier discounts require a negotiated minimum spend, so smaller developers without predictable volume do not get Microsoft’s most competitive published rate.
  • Custom Translator model training and management add operational complexity beyond simple API calls, requiring parallel training data the buyer must supply and maintain.
  • Adopting it while already using a different primary cloud (AWS or Google Cloud) means managing a second cloud billing relationship purely for translation, which is administratively unappealing for some teams.

Microsoft charges $10 per million characters for standard translation, about half Google’s $20 NMT rate.

No, Amazon Translate is a developer API only, accessed through the AWS console and SDKs, with no separate public-facing app.

Microsoft Translator: Is there a free tier?

Yes, for limited monthly volume, though Microsoft publishes less specific detail on the exact allowance than Google or Amazon do.

Amazon Translate: How much does document translation cost compared to text?

Double the standard rate, at $30 per million characters for Office file formats.

Microsoft Translator: Can I get a discount for high volume?
