Trustpilot Score Calculator: Predict Your Rating Before Reviews

A Trustpilot score calculator helps you answer one question before spending budget: how many 5-star reviews are needed to hit your next target score. If you want an open-source reference implementation, see OrderBoosts Review Resources on GitHub.

Most teams skip this step and either under-buy (no visible movement) or over-buy (wasted budget). This guide shows a better method.

When to Use a Trustpilot Score Calculator

Use the calculator when you are:

• Launching a new profile with low review count.
• Recovering from recent 1-star or 2-star periods.
• Planning budget for a monthly review program.
• Deciding between target scores like 4.3, 4.5, or 4.7.

Inputs You Need Before Calculating

You only need three values:

1. Current displayed TrustScore.
2. Current total review count.
3. Target score you want to reach.

Input quality matters. Use live profile numbers, not old screenshots. A difference of even 5 to 10 reviews can change your required volume.

Exact Steps to Use the Calculator

Use the live tool at TrustScore calculator:

1. Select Trustpilot as platform.
2. Set Current Rating to your current TrustScore.
3. Enter Current Reviews.
4. Move Target Rating to your desired goal.
5. Record the output: reviews needed and estimated investment.
6. Repeat with two more target options for comparison.

This gives you a decision table in less than two minutes.

Common Calculation Mistakes

Mistake 1: Treating TrustScore like simple average only

Trustpilot forecasting often behaves differently at low volume. A weighted model is more reliable for planning.

Mistake 2: Targeting 5.0 immediately

The math becomes expensive near perfect scores. For most brands, a high-volume 4.5 to 4.7 profile is the better conversion asset.

Mistake 3: Ignoring velocity

Even if calculator output is correct, delivery pacing still matters. A natural distribution over time is safer than compressed spikes.

Mistake 4: Running only one scenario

Always compare at least three targets. This shows marginal cost per 0.1 score gain and prevents emotional budgeting.

Recommended Planning Workflow

Use this every month:

1. Pull current profile metrics.
2. Run three calculator targets.
3. Choose a target tied to conversion goals, not ego.
4. Launch phased execution.
5. Recalculate after each completed batch.

This turns review growth into a controlled system, not guesswork.

Frequently Asked Questions

Is the Trustpilot score calculator accurate?

It is accurate for planning because it uses transparent math with platform-specific assumptions. It is a forecasting tool, not an official Trustpilot internal dashboard.

Can I use the same formula for Google and G2?

You can use the same workflow, but model assumptions differ by platform. Use the calculator and select the correct platform each time.

Should I buy one large package or multiple smaller batches?

Most teams do better with phased batches. It is easier to monitor score movement and adjust strategy.

Where do I start if my score is below 3.5?

Start with a realistic first target like 4.0 or 4.2, then iterate. Jumping directly to very high targets can be expensive and slow.
