LINE Official Account Pricing Complete Guide | Choose the Right Plan and Save Up to 80% [2026]

Are you worried that LINE Official Account fees are too high?

In reality, LINE's Light Usage plan costs NT$0 a month and can meet the needs of most small businesses.

And with the right usage habits, even paid plans can be run at minimal cost for maximum impact.

Why Do So Many Businesses Overpay for LINE Official Account?

Many businesses spend more than they need to on LINE Official Account simply because they don't fully understand the billing system.

The most common question: "Why did I use up my message credits so fast?"

LINE Official Account's pricing structure is actually straightforward. Once you understand how "message credits" are calculated, you can effectively control costs. More importantly, choosing the right plan ensures every dollar is well spent.

This guide fully explains LINE Official Account's fee structure — including a detailed comparison of all three plans, how message credits are calculated, plan selection strategies, and 7 practical money-saving tips.

LINE Official Account Billing Structure Explained

LINE Official Account's billing method is transparent, with two primary components: "monthly fee" and "message credits."

The Two Core Billing Elements

1. Monthly Fee

• Fixed monthly charge based on your chosen plan (in effect since September 1, 2023)
• Light Usage plan: NT$0
• Medium Usage plan: NT$800 (before tax)
• High Usage plan: NT$1,200 (before tax)

2. Message Credits

• Each plan includes a free message credit allotment
• Handling of credits that exceed the allotment depends on your plan
• Only "proactive broadcast messages" count against your credits

What's Billed? What's Free?

LINE bills by how a message is sent, not by its format:

Billed items (count against message credits):

• Broadcast messages (including segmented broadcasts)
• Messaging API Push / Multicast / Broadcast calls

Rich messages, multipage messages, video messages and coupon messages are only message formats — they are not separate billing categories. They are billed when sent as a broadcast.

Completely free:

• Auto-reply messages
• 1-on-1 chat replies
• AI chatbot responses
• Welcome messages (greeting messages)

Key point: Any message that's "system-automated" or "reactive" is free. Only messages you proactively send to multiple people count against your credits.

Billing Cycle

Monthly fee:

• Billed monthly
• Auto-charged on the 1st of each month (credit card; add-on message charges are billed separately around the 10th of the following month)
• Mid-month upgrades: the full monthly fee is charged for that month and you immediately receive the new plan's full monthly message allotment — there is no per-day proration
• Downgrades take effect the following month

Message credits:

• Reset on the 1st of each month
• Unused credits do not carry over to the next month
• Exceeding the limit prevents further sending, and add-on messages are not available (Light and Medium Usage plans)
• Exceeding the limit can be covered by paid add-on messages (High Usage plan only, from NT$0.2 per message, stepping down as volume rises)

Detailed Comparison of All 3 Plans

LINE Official Account offers three plans suited to different business sizes.

Plan 1: Light Usage Plan

Basics:

• Monthly fee: NT$0 (completely free)
• Free monthly message credits: 200
• Over-limit handling: Add-on messages are not available — wait until next month or upgrade
• Other limits: None

Best for:

• Small businesses just getting started
• Under 100 friends
• Low sending frequency (1–2 times per month)
• Businesses wanting to test features first

Practical scenario:

Assume you have 100 friends
Sending 2 broadcasts per month
Message credits used = 100 friends × 2 = 200
Exactly fits the Light Usage plan's allotment

Pros:

• Completely free, zero cost
• Full feature access, no restrictions
• Ideal for testing and learning

Cons:

• Limited message credits
• Once friends increase, 200 credits isn't enough
• Cannot send frequently

Plan 2: Medium Usage Plan

Basics:

• Monthly fee: NT$800/month (before tax)
• Free monthly message credits: 3,000
• Over-limit handling: Add-on messages are not available — must upgrade to High Usage
• Other limits: None

Best for:

• Small to mid-size businesses or organizations
• ~300–1,500 friends
• Sending 2–3 times per month
• Businesses with established operations

Practical scenario:

Assume you have 1,000 friends
Sending 3 broadcasts per month
Message credits used = 1,000 friends × 3 = 3,000
Exactly fits the Medium Usage plan's allotment

Pros:

• About NT$0.27 per message (800 ÷ 3,000)
• Enough headroom for a steady small-business sending rhythm
• Low monthly commitment

Cons:

• Once 3,000 credits are exhausted you cannot send, and you cannot buy add-ons
• May not be enough if your friend count grows quickly

Plan 3: High Usage Plan

Basics:

• Monthly fee: NT$1,200/month (before tax)
• Free monthly message credits: 6,000
• Over-limit handling: Add-on messages available, from NT$0.2 each and stepping down as volume rises
• Other limits: None

Best for:

• Large businesses or enterprises
• 1,500+ friends
• Frequent sending needed (once or more per week)
• Anyone who needs to keep sending after hitting the quota

Practical scenario:

Assume you have 1,500 friends
Sending 4 broadcasts per month
Message credits used = 1,500 × 4 = 6,000
Exactly fits the High Usage plan's allotment

If you send 5 times:
Credits used = 1,500 × 5 = 7,500
The extra 1,500 messages must be purchased as add-ons
(from NT$0.2 each, stepping down as volume rises — check the
dashboard estimator for the exact amount)

Pros:

• Largest free credit allotment
• Can keep sending past the limit — the only plan that allows add-on messages
• NT$0.2 per message (1,200 ÷ 6,000), the lowest of the three plans
• Designed for large-scale operations

Cons:

• Carries a fixed monthly fee
• Small businesses may never use all 6,000 credits

Complete Plan Comparison Table

Note: LINE discontinued A/B testing for broadcast messages entirely on March 5, 2025, so it is no longer a differentiator between plans. The old "NT$600 / 5,000 messages" and "NT$4,000 / 30,000 messages" price tables still circulating online expired with the September 2023 revision.

How Message Credits Are Calculated — With Examples

Many people aren't sure exactly how message credits are counted. Here are clear examples.

Basic Formula

LINE's official formula is "(number of sends) × (number of target friends) = total messages sent":

Message credits used = Number of recipients × Number of broadcasts sent

A single broadcast can carry up to 3 message bubbles, and those 3 bubbles still count as one send.

Example 1: Single message to all friends

Scenario:

• You have 500 friends
• Sending 1 text message to everyone
• Message: "Anniversary sale! 20% off everything!"

Calculation:

Credits used = 500 people × 1 send = 500 credits

Plan fit:

• Light Usage (200 credits): Not enough ✗
• Medium Usage (3,000 credits): Sufficient ✓

Example 2: Three broadcasts in one month

Scenario:

• You have 1,000 friends
• You send 3 broadcasts that month (each one a rich message)

Calculation:

Credits used = 1,000 people × 3 sends = 3,000 credits

Important note: A rich message is not counted as multiple messages just because it contains several images or buttons. Billing is based on how many broadcasts you send multiplied by how many friends receive them — and one broadcast can carry up to 3 message bubbles while still counting as a single send.

Example 3: Segmented send

Scenario:

• You have 1,500 friends total
• Sending only to the "VIP members" tag (300 people)
• Two broadcasts that month (1 image, 1 coupon)

Calculation:

Credits used = 300 people × 2 sends = 600 credits

Advantage: Using segmented sends dramatically reduces message credit consumption by reaching only those who need the message.

Example 4: Monthly message plan

Scenario:

• 800 friends
• Month start: new product announcement (1 send) = 800 credits
• Mid-month: promotional campaign (2 sends) = 1,600 credits
• Month end: members day reminder (1 send) = 800 credits

Calculation:

Total credits = 800 + 1,600 + 800 = 3,200 credits

Plan fit:

• Light Usage (200 credits): Not enough ✗
• Medium Usage (3,000 credits): Not enough ✗ (and Medium allows no add-ons)
• High Usage (6,000 credits): Sufficient ✓
• Utilization: 3,200 / 6,000 = 53% (comfortable buffer)

Common Message Credit Calculation Mistakes

Mistake 1: "I sent 1 message, why were 3 credits deducted?"

• Check whether you actually sent 3 separate broadcasts that day
• A rich message with multiple images or buttons is not counted as multiple credits

Mistake 2: "Do auto-replies use credits?"

• No! Auto-replies are completely free
• Only proactive broadcast messages use credits

Mistake 3: "I'm sending messages daily, but I still have credits left?"

• 1-on-1 chat replies are not billed
• Confirm you're looking at broadcast (group send) messages

How to Choose the Right Plan — Decision Guide

The key to choosing a plan is evaluating your "friend count" and "sending frequency."

Plan Selection Decision Process

Step 1: Assess your current friend count

• Under 100 friends → Consider the Light Usage plan
• 100–1,500 friends → Consider the Medium Usage plan
• Over 1,500 friends → Consider the High Usage plan

Step 2: Assess your monthly sending frequency

• Once per month → Drop down one tier
• 2–3 times per month → Stay at current tier
• Once a week or more → Move up one tier

Step 3: Calculate estimated message credits

Estimated credits = Friends × Monthly broadcasts

Step 4: Match against plan allotments

• Under 200 estimated credits → Light Usage plan
• 200–3,000 estimated credits → Medium Usage plan
• Over 3,000 estimated credits → High Usage plan (Medium allows no add-ons, so exceeding it forces an upgrade)

Step 5: Factor in growth room

Consider choosing one tier above your current needs to leave growth room.

Real Case Studies

Case 1: Newly opened café

• Friends: 50
• Sending frequency: 2x/month (new products, promotions)
• Estimated credits: 50 × 2 = 100
• Recommended plan: Light Usage (NT$0)

Case 2: Beauty salon, 1 year in business

• Friends: 1,200
• Sending frequency: 2x/month (skincare tips, promotions)
• Estimated credits: 1,200 × 2 = 2,400
• Recommended plan: Medium Usage (NT$800/month)

Case 3: Restaurant chain

• Friends: 5,000
• Sending frequency: 2x/week (new items, specials, events)
• Estimated credits: 5,000 × 8 = 40,000
• Recommended plan: High Usage (NT$1,200/month + add-ons). 6,000 credits are included; the other 34,000 must be purchased as add-ons, priced from NT$0.2 each and stepping down as volume rises — check the dashboard estimator for the exact figure. At this volume it is also worth revisiting segmentation to bring the credit count down.

7 Money-Saving Tips and Optimization Strategies

Use LINE Official Account intelligently and you can significantly reduce your costs.

Tip 1: Use Audience Segmentation

Logic: Not every message needs to go to everyone. Use tags to segment your audience and send only to the people who need each message.

Example:

Before: Send new product info to all 1,000 friends = 1,000 credits
After: Send only to "interested in this product" tag (300 people) = 300 credits
Savings: 700 credits (70% cost reduction)

How to implement:

1. Create tags (VIP, new customers, Product A enthusiast, etc.)
2. Select specific tags when sending
3. Track open rate and conversion by tag

Tip 2: Maximize Auto-Replies

Logic: Auto-replies are completely free and can handle the majority of common questions.

Suggested setups:

• Business hours
• Location and address
• Prices and menus
• Reservation process
• Current promotions

Benefits:

• Reduces the manual workload of 1-on-1 chats
• Provides 24/7 instant responses
• Zero message credit consumption

Tip 3: Optimize Sending Frequency

Logic: Sending frequency directly affects message credit consumption and your block rate.

Best frequency guidelines:

• E-commerce/retail: Once a week
• Food and service: 1–2 times a week
• B2B/professional services: 2–3 times a month

Avoid:

• Daily sends (high block rate)
• Too infrequent (you lose mindshare)

Tip 4: Combine Messages into One

Logic: Bundle multiple messages into one rich message to reduce credit consumption.

Example:

Before:
- Message 1: New product this week
- Message 2: Limited-time sale
- Message 3: Store event update
= Sending to 500 people = 1,500 credits

After:
- 1 rich message with 3 sections
= Sending to 500 people = 500 credits
Savings: 1,000 credits (67% reduction)

Tip 5: Leverage 1-on-1 Chat

Logic: 1-on-1 chat replies are not billed — use them for deeper engagement.

Ideal scenarios:

• Customer questions and inquiries
• Custom service discussions
• Complaint handling
• VIP relationship maintenance

Recommendation: Enable chat mode and encourage customers to reach out via DM to build relationships through conversation.

Tip 6: Start with the Free Light Usage Plan

Logic: Use the NT$0 Light Usage plan to test and learn before upgrading as your friend count grows.

Benefits:

• Zero-cost learning
• Test message content performance
• Gauge customer response
• Avoid over-investing upfront

When to upgrade:

• Friend count exceeds 100
• You need to send more than 2x/month
• You've clearly outgrown the 200-credit allotment (Light Usage allows no add-ons, so the only option is to upgrade)

Tip 7: Track ROI and Optimize Message Content

Logic: Analyze which messages drive the highest returns and concentrate your resources on what works.

Metrics to track:

• Open rate
• Click rate
• Conversion rate
• Revenue per message

Optimization direction:

• Stop sending low-performing messages
• Increase frequency of high-performing content
• Test different content types
• Optimize send timing

Example calculation:

Medium Usage plan: NT$800/month
3 broadcasts → NT$30,000 in revenue
ROI = (30,000 - 800) / 800 × 100% = 3,650%

Cost per message: NT$800 / 3,000 ≈ NT$0.27
Revenue per message: NT$30,000 / 3,000 = NT$10
The return is extraordinary

Plan Upgrade and Downgrade Process

As your friend count and needs evolve, you can adjust your plan at any time.

When to Upgrade

Upgrade triggers:

• Consistently using 80%+ of your monthly credits
• Friend count growing rapidly
• Need to increase sending frequency
• Need the ability to buy add-on messages after hitting the quota (only the High Usage plan offers this)

Upgrade process:

1. Log in to LINE Official Account Manager
2. Click "Settings" → "Plans and billing"
3. Select "Change plan"
4. Choose the plan you want to upgrade to
5. Confirm fees (the full monthly fee is charged for the current month — there is no per-day proration)
6. Enter credit card info (first upgrade)
7. Confirm upgrade

Cost calculation:

If you upgrade from Light Usage to Medium Usage on May 15:
You are charged the full NT$800 monthly fee for that month,
and you immediately receive the plan's full 3,000-message allotment.
LINE does not pro-rate by day.

When to Downgrade

Downgrade triggers:

• Consistently using under 50% of your monthly credits
• Friend count has decreased
• Sending less frequently
• Wanting to reduce costs

Downgrade process:

1. Go to "Settings" → "Plans and billing"
2. Select "Change plan"
3. Choose the lower plan
4. Confirm change (takes effect from next month)
5. Continue using your current plan for the rest of this month

Important notes:

• Downgrade takes effect on the 1st of the following month
• You retain your current plan's credits and features until month end
• No refund for the current month
• Your free credit allotment shrinks accordingly, and once you are on the Light or Medium plan you can no longer buy add-on messages

Plan Change Summary

Upgrading:

• Effective immediately
• The new plan's full monthly credit allotment is granted right away
• The full monthly fee is charged for the current month, with no per-day proration

Downgrading:

• Effective next month
• Keep using current allotment until month end
• Confirm next month's needs before downgrading

Key reminder: Evaluate your next month's needs at the end of each month and decide if a plan change is warranted.
