The short version

  • Only Microsoft Translator has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; SDL Trados Studio it runs on Windows only, so macOS translators pay for a virtual machine or a second computer before they can accept work.
  • They diverge on capability: Microsoft Translator covers Text translation API, SDL Trados Studio covers Translation memory.
  • 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.

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.

SDL Trados Studio

  • It runs on Windows only, so macOS translators pay for a virtual machine or a second computer before they can accept work.
  • A perpetual licence covers the version you bought, and each major release is a further purchase, so the total cost over five years resembles a subscription without being described as one.
  • The learning curve is long: project settings, filters and memory configuration have to be understood before quality output is possible, which makes casual use impractical.
  • Memories and projects are local by default, and real collaboration needs GroupShare or the cloud tiers at extra cost, so two translators sharing one memory is a paid upgrade.
  • Third party plugins from the app store are maintained by their authors and frequently stop working after a major Studio release, which strands workflows that depend on them.

Answered from the vendors’ own pages

Microsoft Translator: How does Microsoft’s per-character price compare to Google’s?

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

SDL Trados Studio: Is it still called SDL Trados?

The product is now sold as Trados Studio by RWS, which acquired SDL in 2020. Older documentation and job adverts still say SDL Trados.

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.

SDL Trados Studio: Do I need it if my clients use a cloud TMS?

Often yes. Agencies still send Studio packages, and accepting them without the tool means manual conversion and lost memory matches.

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

Yes, through commitment-tier pricing negotiated with Microsoft for a minimum monthly spend.

SDL Trados Studio: Can I run it on a Mac?

Not natively. Translators use Parallels, Boot Camp on older hardware, or a Windows virtual desktop.
