Live support: 100% allocated; 0% unallocated; needs minus known fixed bills = 200.00.

Assumptions used

What this answer assumes

Use take-home income and label the printout with the household, month or pay period before filing it.

Income means monthly take-home money available to allocate, not gross salary before tax and deductions.
The default 50/30/20 split is a budgeting convention, not a legal, tax or financial-planning rule.
Percentages can be edited; if they do not total 100%, the calculator shows the unallocated or overallocated remainder.
Known fixed bills are compared with the needs bucket but are not automatically moved between categories.
The result is a planning worksheet only, not financial advice.

Master’s Tip

How to use the result well

Master’s Tip: print one version with your ideal split and one version using your real bills. The gap between the two is usually where the useful budget conversation starts.

2,000.00 needs; 1,200.00 wants; 800.00 savings/debt100% allocated; 0% unallocated; needs minus known fixed bills = 200.00.

Inputs

Monthly take-home income: 4,000 currency
Needs: 50 %
Wants: 30 %
Savings / debt: 20 %
Known fixed bills: 1,800 currency optional

Method

Monthly take-home income of 4,000 with a 50% needs target gives 2,000. A 30% wants target gives 1,200. A 20% savings or debt target gives 800. If known fixed bills are 1,800, the needs bucket has 200 left for variable essentials before the category is stretched.

Assumptions

Income means monthly take-home money available to allocate, not gross salary before tax and deductions.
The default 50/30/20 split is a budgeting convention, not a legal, tax or financial-planning rule.
Percentages can be edited; if they do not total 100%, the calculator shows the unallocated or overallocated remainder.
