What this calculator does
A budget planner shows where monthly income is going and whether the plan leaves money spare. It is a quick way to spot pressure points before the month starts.
Formula used
Total planned spending is subtracted from take-home income. Each category is also shown as a share of income.
How to read the result
A budget is most useful when it matches real behaviour. Compare this plan with actual bank transactions and adjust categories over time.
Assumptions
- Uses monthly amounts.
- Does not connect to bank accounts.
- Does not judge whether a category is good or bad for your situation.
Sources and checks
This calculator uses a standard public formula. Where rules or thresholds can change, source links are listed on the relevant page.
Frequently asked questions
What if the leftover is negative?
A negative leftover means the plan spends more than the income entered. Reduce a category, raise income or decide which costs need priority attention.
