Target Rating Point (TRP) Calculator
Measure the media weight delivered specifically within your target demographic audience (TRP / TARP).
Calculate Target Rating Point (TRP)
Target Rating Point (TRP) Formulas & Reverse Equations
Use these standard and algebraic reverse formulas in spreadsheets, agency decks, or media plans:
Solve for TRP
TRP = Target Audience Reach (%) × FrequencySolve for Target Reach Percentage
Target Reach (%) = TRP ÷ FrequencySolve for Frequency
Frequency = TRP ÷ Target Reach (%)Understanding Target Rating Point (TRP)
Target Rating Point (TRP) — widely referred to as Target Audience Rating Point (TARP) in Australian and New Zealand media agencies — refines GRPs by measuring reach strictly inside your primary demographic audience (such as Grocery Buyers 25–54 or People 18–39) rather than the entire population.
When to Use Target Rating Point (TRP)
Use TRP / TARP when buying demographic-guaranteed TV, BVOD, radio, or cinema schedules and calculating Cost Per Point (CPP / CPT).
Industry Benchmarks & Planning Context
If a schedule delivers 220 GRPs across all households but 165 TRPs against People 25–54, the difference represents spill impressions outside your core buying demographic.
Frequently Asked Questions About TRP
How do you calculate Target Rating Points (TRP / TARP)?
Multiply the percentage of your specific target demographic reached (as a whole number from 0 to 100) by the average exposure frequency within that target group: TRP = Target Reach (%) × Frequency.
Are TRP and TARP the same metric?
Yes. TRP (Target Rating Point) and TARP (Target Audience Rating Point) are identical mathematically. TARP is the standard terminology used by OzTAM and media agencies across Australia and New Zealand, while TRP is standard across North America and Europe.
