Set your inputs and units
Enter amounts in THB and choose a period and rate basis that match the scenario you want to model.
Compound interest
Project compound growth with monthly contributions, contribution timing and a month-by-month table.
Calculation result
Adjust the example inputs, then calculate to see your result.
The chosen annual rate is converted to equivalent monthly growth. Constant rate; no tax, fees or inflation. Calculations retain precision before display rounding to two decimals, half up, so displayed rows may differ slightly from totals. Goal contributions round up to cents. Returns are not guaranteed.
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
10,000 THB initially plus 1,000 THB at each month-end for 12 months at 0% gives 22,000 THB.
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.
