Free Category Budget Allocator Calculator

What is a category budget allocator calculator?

A category budget allocator calculator helps you assign income intentionally before the month begins.

Enter monthly income and your category amounts for housing, food, transport, savings, and fun. The tool shows unassigned money and each category share of income.

Unassigned = Income − (Housing + Food + Transport + Savings + Fun)

Use this with our budget categories list to define practical category boundaries.

Real-life example (try this in the calculator)

If monthly income is $4,200 and allocations are $1,400 + $500 + $250 + $600 + $1,400:

Line item Amount Calculator field
Monthly income $4,200 Monthly income ($)
Housing $1,400 Housing ($)
Food $500 Food ($)
Transport $250 Transport ($)
Savings $600 Savings ($)
Fun $1,400 Fun ($)
Total assigned is $4,150, leaving $50 unassigned.

A small positive unassigned amount gives breathing room for surprises.

How to read your results

  • Unassigned budget — Positive means you still have income left to assign. Negative means allocations exceed income.
  • Housing % of income — Shows how much of monthly income goes to housing costs.
  • Savings % of income — Tracks your savings contribution as a share of monthly income.

If unassigned is negative, adjust category caps before the month starts.
