Budget Planner

A budget planner is a simple map of money in and money out over a period you choose. You list take-home income (salary, benefits, investments, partner income, and anything else you receive) and the expenses that keep your household running: housing, food, transport, insurance, children, debt, and leisure. This Justools Budget Planner turns those line items into clear totals so you can see leftover cash or a shortfall without a spreadsheet template. It is built for real household numbers, not city averages or business profit. Use it when you want a private, browser-based snapshot you can adjust week to week or month to month.

A budget planner makes cash flow visible before the month runs out. When income and every major bill sit in one place, it is easier to spot overspending, decide what to cut, and plan savings with intent instead of hope. Households often track pay and rent carefully but lose track of dining, subscriptions, transport, or minimum debt payments. Categorized sections and a live leftover figure help you catch those leaks early. Partner income lines and custom items mean you can model a single earner, a couple, or a quirky expense without forcing a one-size template. The sticky summary keeps the result in view while you edit, and CSV download gives you a copy for spreadsheets or shared planning without creating an account.

Enter take-home (net) pay: the amount that actually lands in your bank after income tax, social contributions, and other payroll deductions. Gross pay is the larger pre-deduction figure on a contract or payslip. If you budget with gross, you will overstate income and invent a surplus that never reaches your account. Rent, groceries, and loan payments are paid from take-home cash, so the planner should use the same base. Apply the same rule to benefits, investment distributions you actually receive, and partner income. If your pay varies, use a typical recent take-home amount or a conservative average. Tip: check a bank deposit or payslip “net pay” line rather than the headline salary.

Leftover (or shortfall) is total income minus total expenses for the period you selected under View totals as. A positive leftover is what remains after the bills you entered; a negative shortfall means expenses exceed income for that view. Savings rate is leftover divided by income, shown as a percentage when income is greater than zero. It is a planning signal, not a bank balance. If you leave unused lines blank, they count as zero. Custom items you add are included in the same totals. Change View totals as to weekly, monthly, or annual if you prefer to read the summary in a different cadence; every line is converted so the math stays consistent.

Yes. Each section has an Add item control. Use it for anything the preset list does not cover: pet care, childcare extras, side-hustle income, strata special levies, club fees, or a one-off annual bill you want to track every month. Give the line a clear name, enter the amount, and choose weekly, monthly, or annual to match how you pay it. Custom lines are included in section subtotals, the sticky summary, and the CSV export. Remove a custom line anytime if you no longer need it. Preset lines stay available as a reusable checklist, so you can leave them blank and still keep the structure for next time.

It is for individuals and households who want a fast, private way to see whether their real take-home income covers day-to-day costs. Couples can fill partner income lines; singles can leave them blank. Renters and owners both fit: housing labels stay general (rent or mortgage, property fees). It is not a tax calculator, debt payoff scheduler, or bank-linked money manager. If you already use a spreadsheet, you can still use this tool for a quick second opinion and export CSV. If you are starting from scratch, fill Income first, then the expense sections you actually use, and watch leftover update as you go.
