What is BudgetAtlas?
BudgetAtlas is a forward-planning budgeting tool, not an expense tracker. Instead of looking back at where your money went, BudgetAtlas helps you plan ahead so you know exactly where every pound will go before you spend it.
Why Use BudgetAtlas?
- Know what you can afford before the month starts
- Spot problems early and adjust your spending before it's too late
- Make informed decisions about what fits in your budget
- Build confidence knowing your spending plan is solid
- Your privacy protected — all data stays on your device, never on our servers
Unlike expense trackers that show you where your money went, BudgetAtlas lets you visualize and plan where your money will go. Think of it as a map for your month — you chart your course before you start the journey.
Understanding the Features
A detailed walkthrough of every feature and what it does for you.
Monthly Income
This is your total expected income for the month. This is the foundation of your budget — the amount you have available to allocate.
What to Include:
- • Salary/wages (after tax)
- • Freelance or side income
- • Benefits or regular payments
- • Any other regular income sources
Budget Usage Progress Bar
The visual progress bar at the top of the app shows how much of your monthly income you've allocated to expenses. It changes color to give you instant feedback:
Green (0-75%)
You're in a healthy range with room to spare.
Yellow (75-95%)
Getting close — be mindful of remaining funds.
Red (95%+)
Over budget or very close. Time to adjust.
Expense Items & Fields
This is where you add each expense item. Each item has several fields:
The name or description of the expense (e.g., "Rent", "Netflix", "Weekly Groceries").
The type of expense (see Categories section below). This helps organize your spending and auto-assigns to a 50/30/20 rule bucket.
The cost for one occurrence of this expense.
How many times this expense occurs per month (e.g., 1 for monthly rent, 4 for weekly groceries, 2 for fortnightly phone bill).
Whether this is a Need, Want, or Savings/Debt item (see 50/30/20 Rule section). This is auto-assigned based on category but you can override it.
Calculated automatically: Price × Frequency.
What percentage of your monthly income this item represents.
Multiple Budgets
You can create, save, and manage multiple budgets. This is useful for planning different months, comparing scenarios, or managing budgets for different purposes.
- Create: Click "Create New Budget" and give it a descriptive name (e.g., "March 2026", "Holiday Budget").
- Load: Select from the dropdown and click "Load" to switch between budgets.
- Duplicate: Make a copy of the current budget to use as a template for next month.
- Edit: Rename a budget to keep things organized.

Spending Distribution Chart
A pie chart shows how your budget is split across different categories. Each slice represents a category, color-coded for easy identification. The legend shows the percentage each category takes up.
💡 Tip: Enable Budget Guidelines
Toggle "Show budget guidelines" to see if any category is taking up more of your budget than recommended. Orange or red indicators will appear next to categories that exceed common financial benchmarks.

The 50/30/20 Rule
A proven budgeting framework to balance essentials, enjoyment, and future security.
What is the 50/30/20 Rule?
The 50/30/20 rule is a simple budgeting guideline that divides your after-tax income into three categories:
Essential expenses you must pay to live and work.
- • Rent/Mortgage
- • Groceries
- • Bills & Utilities
- • Transport
- • Insurance
Non-essential spending that makes life enjoyable.
- • Dining out
- • Entertainment
- • Hobbies
- • Shopping
- • Holidays
Future security and paying down debt.
- • Emergency fund
- • Savings goals
- • Debt repayment
- • Investments
- • Pension
How BudgetAtlas Uses the 50/30/20 Rule
BudgetAtlas automatically assigns each expense to a bucket (Needs, Wants, or Savings/Debt) based on its category. For example:
- Accommodation, Groceries, Utilities, Vehicle, Transport → Needs
- Social & Leisure, Shopping & Personal → Wants
- Savings & Financial → Savings/Debt
💡 You Can Override the Auto-Assignment
After calculating your budget, you'll see each item's assigned bucket. If you disagree with the assignment, you can manually change it. For example, if you consider Netflix a "Want" rather than a "Need", you can reclassify it.
Why This Matters
The 50/30/20 rule breakdown in BudgetAtlas shows you if your spending is balanced. If you're spending 70% on needs and only 5% on savings, you can see the imbalance and adjust.
⚠️ Be Honest With Yourself
The 50/30/20 rule only works if you're honest about what's a Need vs. a Want. A £100 gym membership might feel essential, but if you rarely use it, it's a Want. Netflix might feel like a Need, but it's entertainment — a Want. Honest categorization leads to accurate budgeting.
Your 50/30/20 Breakdown
After you calculate your budget, BudgetAtlas displays your actual spending distribution and compares it to the 50/30/20 guideline. Use this to identify areas where you might be overspending or under-saving.
Best Practices & Tips
Get the most out of BudgetAtlas with these practical tips.
📅 Plan Before the Month Starts
Build your budget at the end of the previous month or at the very start of the new month. This gives you a roadmap before you start spending.
🔍 Be Realistic, Not Optimistic
Don't underestimate costs. If you usually spend £200 on groceries, don't budget £150 and hope for the best. Use real numbers.
💡 Account for One-Off Costs
Birthdays, car repairs, annual subscriptions — these aren't monthly, but they still need to be budgeted. Add them in the month they occur.
💰 Include Savings as an Expense
Treat savings like a bill. If you want to save £200/month, add it as an expense item under "Savings & Financial". This ensures you prioritize it.
🔄 Review and Adjust Monthly
Life changes month to month. Use the "Duplicate Budget" feature to copy last month's budget, then tweak it for the new month.
📊 Use the Pie Chart & Guidelines
Enable "Show budget guidelines" to see if you're spending too much in any one category. Orange or red warnings mean you're exceeding common benchmarks.
📄 Export PDFs for Record-Keeping
Save a PDF of each month's budget for your records. This helps you track progress over time and see where you've improved.
🎯 Be Honest About Needs vs. Wants
The 50/30/20 breakdown only works if you're truthful. Don't call a luxury item a "need" just to feel better. Honest budgeting is effective budgeting.
