Future five-star reviews
26
The rating math only. It assumes future five-star reviews; it is not advice to ask only happy customers.
Rating math and review habit
Google Review Calculator for Your Target Rating
This free Google review calculator shows how many future five-star reviews would be needed to reach a target rating from your current review count and average. It also turns completed jobs into a realistic request habit. It is rating math, not a way to filter customers, buy reviews, or guarantee a Maps result.
Interactive tool
Use your own numbers.
Start with the current review count and rating shown on Google. Then use completed jobs—not inbound leads—to set an honest request routine your team can maintain.
Request habit
2/week
59 completed customers to ask each month at the response rate entered.
Estimated time
4 months
Time to reach the rating target if the request habit and response rate remain consistent.
Assumption: The rating calculation assumes future five-star reviews solely to show the math. Never offer incentives, ask only likely-positive customers, or pressure anyone to leave a particular rating. Ask real customers for an honest review after a real experience.
Use this when
- Your review count is falling behind credible local competitors.
- The team asks inconsistently or only after a problem has already happened.
- You want an honest target tied to completed customer work.
What this cannot tell you
The tool helps frame an owner decision. It does not replace an audit of the live market, your competitors, your service area, or what your team can actually handle.
