GRP Calculator

How to Use the GRP Calculator – Step-by-Step

1. Enter Reach (%) — percentage of target audience exposed to the campaign. 
2. Enter Frequency — average number of times each person is exposed. 
3. Click Calculate to view the GRP. 
4. Interpret results — higher GRP means stronger exposure, but efficiency depends on cost.

Validation: Values must be ≥ 0. Reach (%) must be ≤ 100. Use consistent campaign periods (e.g., weekly, monthly).

Understanding Your GRP

Once you click Calculate, the tool shows the GRP (Gross Rating Points) for your campaign.

• GRP = Reach (%) × Frequency 

Result Interpretation:

GRP 100 = Audience exposure equivalent to 100% of the population once.
GRP 200 = Audience exposure equivalent to 100% of the population twice, or 50% exposed four times.
Higher GRP suggests stronger impact but must be balanced against efficiency and cost.

Practical Examples

Example 1 — TV Campaign

• Reach: 60% 
• Frequency: 3 
• GRP = 60 × 3 = 180 

Interpretation: The campaign delivers 180 points, meaning strong reach with decent repetition.

Example 2 — Radio Campaign

• Reach: 40% 
• Frequency: 5 
• GRP = 40 × 5 = 200 

Interpretation: Though reach is lower, higher frequency creates equal or stronger weight compared to TV.

Industry GRP Benchmarks

Benchmarks vary by campaign objectives, market size, and budget.

Growth Tips & Business Impact

• Balance reach and frequency — don’t overspend chasing both simultaneously. 
• Align GRP with goals — branding campaigns need higher GRPs; tactical offers may need less. 
• Optimize mix — test different media channels for efficiency. 
• Track cost efficiency — calculate CPP (Cost per Point) to compare value across channels. 
• Use GRP as a planning tool — combine with CPM and ROI to see full picture.
