Thailand overstay fine calculator
Estimate your overstay fine
Estimated fine
Enter the number of days to estimate the fine.
This is an estimate using 500 THB per day, capped at 20,000 THB. It does not determine entry bans or your individual outcome. Confirm with Thai Immigration.
Entry bans need separate confirmation
Entry bans apply in caught/surrender circumstances; an overstay of more than 90 days leads to a 1-year ban under the rule covered here. Confirm how the circumstances apply with immigration.
Act before your permission expires
Apply for any extension — see the 30-day visa extension guide — before the permitted stay ends. A 90-day report is not an extension of stay.
Frequently asked questions
How is the overstay fine estimated?
Multiply the number of overstay days by 500 THB, up to a maximum fine estimate of 20,000 THB. This is an estimate; confirm with Thai Immigration.
Does the calculator determine an entry ban?
No. It estimates the fine only. Entry bans apply in caught/surrender circumstances; an overstay of more than 90 days leads to a 1-year ban under the rule covered here. Confirm how the circumstances apply with immigration.
Are all ban tiers and caught/surrender distinctions verified?
Unverified - confirm with Thai Immigration. Longer overstays carry longer bans, up to 10 years — unverified; confirm. Further tiers and the distinctions between being caught and surrendering are not fully verified in this guide.
Does the 20,000 THB fine cap limit an entry ban?
The cap applies to the monetary fine estimate only. It does not determine an entry ban or your individual outcome. The guide treats entry bans separately and leaves further ban tiers and caught-versus-surrender distinctions unverified. Confirm those circumstances directly with Thai Immigration.
What the fine estimate includes
The calculator applies the daily rate and the maximum fine stated on this site. Enter the number of overstay days as a whole number; confirm the number of days with Thai Immigration. The result is an estimate of the monetary fine, not a decision about permission to stay or future entry.
The maximum fine is a limit on this calculation. It does not establish that an overstay has no other consequences, and the tool does not assess an entry ban. Read the separate ban notice and ask Immigration how the circumstances apply to you, including the distinction between being caught and surrendering.
| Task | What it does |
|---|---|
| Fine estimate | Multiplies overstay days by 500 THB and caps the estimate at 20,000 THB. |
| Extension application | Must be made before current permitted stay ends; exemption approval is at the officer’s discretion. |
| TM47 report | Reports a stay of more than 90 consecutive days. It is not an extension. |
| Change of visa type | The guide states an application should be submitted at least 15 days before current permission expires. |
Use the reporting and visa guides for the wider context. Keeping a reporting deadline and keeping within your permitted stay are separate responsibilities. A calculation on this page cannot resolve an expired permission or substitute for confirming your next steps with Thai Immigration.
