Savings goal

Find the monthly contribution needed for a savings target and compare it with a zero-return scenario.

Monthly savings change every 12 months, first in month 13. Contribution changes range from −100% to 1,000%.

Calculated in your browser. Your inputs are not saved or sent from this device.

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

01

Set your inputs and units

Enter amounts in THB and choose a period and rate basis that match the scenario you want to model.

02

Check the assumptions

Review contribution timing, day-count basis or reserve duration. Financial products do not all use the same rules.

03

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

Starting from zero, a 12,000 THB target in 12 months at 0% requires 1,000 THB each month.

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.
