Set your inputs and units
Enter amounts in THB and choose a period and rate basis that match the scenario you want to model.
Withholding and gross-up
Calculate withholding and gross-up with an explicitly chosen rate, separating VAT from the intended net amount.
Calculated in your browser. Income and results are not saved or transmitted.
3% and 7% are editable examples, not rates for every contract. Withholding uses the pre-VAT base. Base and tax round to satang, half up; any target difference is shown. No tax certificate is issued.
How to use this calculator
Check the assumptions
Review contribution timing, day-count basis or reserve duration. Financial products do not all use the same rules.
Calculate and compare
Read the result and table, then change inputs to compare. Copy the result or reset without leaving this page.
A worked example
Illustrative calculation
A 10,000 THB fee with assumed 3% withholding and 7% VAT gives 300 THB withheld, 700 THB VAT and 10,400 THB transferred.
Compare a second scenario
Copy your first result, then change only the amount or duration to see how that assumption changes the outcome.
Common questions
Where does my information go?
Calculations run in your browser. Financial inputs are neither saved locally nor sent to analytics. Reloading restores the initial values.
Does this match a bank statement or guarantee a return?
This is an estimate under your assumptions, not a guaranteed return. Actual payment dates, fees, taxes and contractual rounding can change the result.
