Home Budget Calculator for
Students & Teens

Add up your real monthly costs — food, rent, bills, and everything else — and see your total by month or projected across the year. Two minutes with honest numbers tells you more than any budgeting lecture.
Total monthly spending $0
Left over each month $0
Savings rate –
Left over per year $0

Tip: use real numbers from last month — your bank app knows the truth.

How to Use This Budget Calculator

  • Pull up your bank app and use real numbers from last month — not what you hope you spend.
  • Put food, rent (or board), and fixed bills in their own fields; everything else — subscriptions, rides, coffee — goes in Miscellaneous.
  • Slide the months to project the total: 12 months of a $40/month habit is the number that changes behaviour.

Try This

Enter just your Miscellaneous spending and set the slider to 12 months. For most students that number lands between $1,500 and $3,000 a year — money nobody remembers spending. That is your savings opportunity hiding in plain sight.

A Teacher’s Tips

If you get paid irregularly, budget on your lowest typical month so a slow month never breaks you. And treat savings like a bill: decide the amount first, then budget what remains — not the other way around.

Budget Calculator FAQ

What is the 50/30/20 rule?

A simple starting split: roughly 50% of income to needs, 30% to wants, 20% to savings. As a student living at home your “needs” are lower — which means your savings percentage can be much higher than an adult’s. Use that window.

How often should I update my budget?

Check it monthly, rebuild it whenever your income changes — new job, more shifts, school year to summer.

What counts as a “bill” as a teenager?

Anything that charges you automatically: phone plan, streaming, gym, app subscriptions. They feel small individually — the calculator shows what they cost as a group.
