We value one member post at ฿170 (about $5).
That is near the bottom of what small Thai creators charge for one sponsored Story — and a member's post is a real workout at your gym, not an ad. Here is the arithmetic, every source linked, and a calculator for your own numbers.
What a sponsored Story costs in Thailand
The closest thing you can buy is a sponsored Story from a small local creator. Published 2026 rates:
Typical Bangkok Story frame: ฿1,200
Our value per member post: ฿170 ≈ $5 Exchange rate ฿33.6 = $1, Bank of Thailand, 2 Oct 2026 3
Creators have bigger audiences than most members, so we never scale their price by follower count. ฿170 sits low in the paid range on purpose: a conservative planning figure, not a ceiling.
Who actually sees a member's post
On accounts with 1,000–5,000 followers, a Story reaches about 10% of followers — 9.55% for photos and 10.40% for video, measured across 161,180 Stories 4.
And they trust it: 88% of people trust recommendations from people they know 5. In a 2026 Southeast Asia survey that included Thailand, recommendations from family and friends were the most influential reason to buy 6. A sponsored Story is meant to carry a paid-partnership label; your member's post is simply theirs.
Does ฿170 a post pay back? Check it with your own fee
Gyms already put a price on a referred member: Virgin Active gives the referring member free months once the new member has paid 7. So a fair value for one new member is about one month's fee. Put in your own numbers:
At ฿4,500 a month, ฿170 a post pays back if about 1 in 26 member posts brings in one new member.
Posts per new member = monthly fee ÷ value per post
New members needed = value per month ÷ monthly fee
230 posts a month is what one busy Bangkok location already produces on ForgeLog. ฿4,500 is a starting value — type in your own fee. You decide whether one new member per that many posts is believable for your gym.
What we do not claim
- Posts are counted as shares. We count each time a member shares their card; Instagram does not tell us whether every share was published.
- ฿170 is a planning value, not revenue. It is what comparable content costs to buy, not cash in your account.
- We do not promise sign-ups. The calculator shows how many new members would justify the value; the real number depends on your gym.
