Legacy Search Retention Calculator

Model the cost of keeping former employee Google Workspace data on Archived User licences, and what comes back when you migrate it to Lightning Legacy Search.

What is this tool?

A quick model of what your organisation is paying today to keep former-employee Workspace data searchable via Google's Archived User licence, and what Legacy Search can give back.

How to use it

Enter your active headcount, tune the archive multiplier(how many former staff you're carrying), then decide what percentage of those archives are candidates for migration.

What it tells you

Your current Archived User spend, the annual saving from migrating a share of those accounts to Legacy Search, and cumulative savings over three and five years.

Configuration

10,000
500500,000
125%

Former-employee accounts as a share of current active headcount. High-turnover sectors (education, retail, gov) often sit at 200%+.

£1.90/mo

Google's published AU licence cost per former user per month. Default reflects the public list rate; adjust for your contract.

50%

Not every archived account needs to migrate. Dormant content that hasn't been touched in years is the obvious first wave. We model 50% as a realistic baseline.
