What is the influencer sponsorship pricing and ROI calculator?

This calculator estimates fair sponsorship fees for Instagram, YouTube, TikTok, and blogs, then converts the campaign into advertiser-side ROAS and creator-side after-fee income. It follows the Korean source structure instead of using one generic follower multiple.

The Korean influencer marketing market is described as about KRW 2.5 trillion in 2026, with advertisers allocating more than 12% of digital ad budgets to influencer campaigns. MCNs such as Sandbox, Treasure Hunter, Collab, and DIA TV are used as market references.

Legal disclosure point

The 2026 Fair Trade Commission recommendation and endorsement advertising guide requires visible disclosure such as #ad or #sponsored. Missing disclosure can create liability for both the advertiser and the creator.

Platform pricing logic

Instagram, YouTube, TikTok, and blog references

  • Instagram feed median rate is modeled at KRW 25 per follower. Image posts use 1.0x, carousel 1.15x, Reels 1.30x, a single story 0.35x, and a three-story set 0.85x.
  • Instagram engagement above 3% adds 1.10x per 1 percentage point, capped at 1.5x.
  • YouTube long-form branded integration is modeled at KRW 90 per view, PPL at KRW 50 per view, Shorts at KRW 12 per view, and live streaming at average concurrent viewers x KRW 25.
  • YouTube engagement above 5% adds 1.05x per 1 percentage point, capped at 1.4x. Finance can add 1.40x, beauty 1.30x, and tech 1.20x.
  • TikTok follower rates are KRW 25 for nano, KRW 40 for micro, KRW 55 for mid-tier, and KRW 75 for macro or mega creators; live content uses 1.2x.
  • Blog pricing uses daily unique visitors x KRW 250 with a minimum of KRW 100,000, and long-tail SEO value can be 2x to 3x over one year.

Creator payout and package discounts

  • Top Korean MCNs are described as exceeding KRW 500 billion of sales in 2026, with management fees commonly around 15% to 25%.
  • A multi-channel package can use a 5% discount per additional channel, capped at 20%.
  • A beauty Instagram creator with 50,000 followers, 4% engagement, beauty 1.30x, engagement 1.10x, and Reels 1.30x is estimated near KRW 240,000 per post.
  • Four posts per month produce about KRW 960,000 gross and about KRW 815,000 net after a 15% MCN fee.

Advertiser ROI workflow

Funnel formula

  • Impressions become reach after an engagement adjustment of roughly 0.6 to 1.0.
  • Clicks are reach x CTR, commonly 1.5% to 3% in the guide.
  • Conversions are clicks x CVR, commonly 2% to 6%.
  • Immediate revenue is conversions x average order value, and LTV revenue applies a 1.5x to 4x customer lifetime value multiple.
  • LTV-ROAS above 300% is excellent, 200% to 300% is acceptable, 100% to 200% is break-even, and below 100% is loss-making.

Campaign example

In the Korean example, a KRW 2,500,000 sponsorship with KRW 35,000 average order value, 50% gross margin, 3% CTR, 5% conversion rate, and 2.5x LTV multiple produces about 320% LTV-ROAS, which falls into the excellent range.
