After expenses, the remaining amount covers your savings target.

Method and scope

Monthly surplus equals income minus housing, food, transport, bills and other spending. The saving goal is compared separately rather than deducted twice.

A negative surplus means planned expenses exceed income. A positive surplus is a budget estimate rather than your current bank balance.

Convert annual expenses into monthly averages before entering them. This tool does not automatically track transactions or maintain an account ledger.

What this helps you do

How the calculation works

Monthly surplus equals income minus housing, food, transport, bills and other spending. The saving goal is compared separately rather than deducted twice.

Worked example

With TWD 50,000 income and TWD 35,000 expenses, the surplus is TWD 15,000. A TWD 12,000 saving goal leaves a TWD 3,000 margin.

Understanding the answer

A negative surplus means planned expenses exceed income. A positive surplus is a budget estimate rather than your current bank balance.
