Should I use gross or net income?

Use net (take-home) income — the amount deposited into your bank account after taxes and payroll deductions. Budgeting against gross income leads to overspending because you cannot spend money that never reaches your account.

What is the 50/30/20 rule?

A popular rule of thumb: 50% of take-home pay for needs (housing, food, utilities), 30% for wants (dining out, subscriptions, hobbies), and 20% for savings and debt repayment beyond minimums. It is a starting point, not a strict requirement.

How often should I revisit my budget?

Monthly at minimum. Compare what you planned to what you actually spent. Budgets that are never checked tend to drift away from reality within a few months.

Monthly Budget Calculator

A monthly budget calculator helps you allocate your take-home income across fixed expenses (rent, loan payments), variable spending (groceries, utilities), and savings goals. Seeing the numbers in one place makes it easier to spot where money is leaking and make intentional trade-offs.

How it works

Formula & methodology

The calculation is straightforward: Net = Income − Total Expenses. A positive result means you have a surplus; a negative result means you are spending more than you earn. The useful part is breaking expenses into categories so you can see which category is the biggest drain relative to your income.

Example

Worked example

Example: $5,000 take-home income minus $1,400 rent, $450 car payment, $600 groceries/dining, $200 utilities, $300 subscriptions/entertainment, and $300 savings contribution leaves a $1,750 monthly surplus.

Tips

Practical tips

Track your actual spending for one full month before building a budget — most people underestimate variable categories like dining out and subscriptions by 20-30%.
Review recurring subscriptions every 3 months; forgotten subscriptions are one of the most common silent budget leaks.
If your surplus is consistently negative, cut discretionary categories (entertainment, dining) before fixed ones (rent, insurance) — fixed costs are harder to change quickly.
