Figures are computed on your device; nothing is sent anywhere.

Formula

total = rent + food + transport + books + mobile + other; leftover = income - total

How the calculation works

The tool adds the rent, food, transport, books, mobile and other amounts into one monthly expense figure.

It subtracts that total from your monthly income or allowance to get the amount left over.

The leftover is returned as is, so a negative number shows you are spending more than you receive.

Common mistakes

When to use it

Worked example

A student with 15000 taka income spending 5000 on rent, 4000 on food, 1500 on transport, 1000 on books, 500 on mobile and 800 on other has 2200 taka left each month.

Total ৳12,000.00
Leftover 3,000.00

Common questions

What if the leftover comes out negative?

A negative leftover means expenses are above income, so trim the largest line or add tutoring income to close the gap.
