About the Hindi Language Interface Planner
What is the Hindi Language Interface Planner?
This planner estimates the hindi localization cost of an app or website, and the cost of adding more Indian languages.
It covers translation, review and on-screen testing, and estimates how long translation will take.
How to use the Hindi Language Interface Planner
- Words to Translate (English source) (sample: 20,000)
- Indian Languages (Hindi = 1) (sample: 1)
- Translation Rate (₹ per word) (sample: 2)
- Review / Proofreading (% of translation cost) (sample: 30)
- App / Website Screens to Test (sample: 60)
- Testing Hours per Screen per Language (sample: 0.5)
- Tester Rate (₹ per hour) (sample: 600)
- Words per Translator per Day (sample: 2,000)
- Translators per Language (sample: 1)
- Press Plan Localization (results also refresh as you type). The result card shows the Total Localization Cost, along with Translation, Review and proofreading, Linguistic and UI testing and Cost per language.
Formula used
Cost = Words × Rate × Languages × (1 + Review %) + Screens × Test hours × Tester rate × Languages

| Tip | Keep strings in resource files (not images) and avoid joining sentence fragments – Hindi word order differs from English |
Tips for using the Hindi Language Interface Planner
- Give translators context and screenshots – the same English word can need different Hindi words.
- Test on real devices: Devanagari conjuncts and matras need proper font support.
