Affordability Calculator

Estimate what you can afford based on your income. Enter your monthly income, expenses and savings goal to see your disposable income, an affordable budget and savings potential.

Enter your monthly income, your monthly expenses and a savings goal. The calculator finds your disposable income, a suggested affordable budget (half of disposable income) and what you could save after your goal.

Disposable income
Affordable budget (50% of disposable)
Savings potential

An affordability calculator shows how much spending room you have each month after essentials, suggests a budget, and reveals what you could put toward savings — the starting point for any spending decision.

The maths

  • Disposable income = income − expenses
  • Affordable budget = 50% of disposable income (a simple guideline)
  • Savings potential = what's left after your savings goal

Examples

  • $5,000 income − $3,000 expenses = $2,000 disposable
  • Affordable budget = $1,000
  • After a $500 goal, $1,500 could still be saved

Frequently asked questions

Why 50% of disposable income?

It's a conservative rule of thumb leaving room for both savings and fun. Adjust the percentage to your situation — the 50/30/20 rule splits income into needs, wants and savings.

What if my expenses exceed my income?

Disposable income goes negative, signalling you're spending more than you earn. The affordable budget and savings potential will then be zero — time to cut costs or raise income.

Just for the giggles, much love.
