How To Budget With Just One Spreadsheet

Most people who struggle with budgeting aren't using too few tools — they're using too many. Multiple apps, several tabs, a notebook on the side. The result is a fragmented picture of your finances that's impossible to act on.

The solution isn't more tools. It's one tool, used consistently.

Why One Spreadsheet Is Enough

A single, well-structured spreadsheet can hold everything you need to manage your money: your income, your fixed costs, your variable spending, and your savings target. When it's all in one place, you see the full picture instantly — no switching between apps, no reconciling different numbers.

What Your One Spreadsheet Should Include

Monthly income

All sources of income in one field. Salary, freelance, side income — your total starting point.

Fixed expenses

Rent, insurance, subscriptions — costs that don't change. Enter once, review monthly.

Variable spending

Groceries, transport, dining out. Estimate at the start of the month, adjust as needed.

Savings target

What you want to set aside this month. Visible at a glance so you can protect it before spending.

The One Rule That Makes It Work

Open it once a month. That's it. Set a recurring reminder — payday works well — and spend 10 minutes updating your numbers. That single habit, repeated every month, will give you more financial control than any app or complex system ever could.

The Right Spreadsheet For This

The Simply Budget Planner for Excel is designed around exactly this one-spreadsheet approach. Everything you need is in one clean layout — no tabs to navigate, no formulas to break, no setup required. Just open it, fill it in, and you're done.
