Monthly Budget Planner
Our budget planner helps you map your monthly income against all your regular expenses — seeing at a glance how much you spend, how much you save, and where the gaps or opportunities lie. A clear monthly budget is the foundation of every financial improvement, from debt reduction to building a home deposit.

Plan your monthly budget — enter your income and all outgoings to see what you have left and where you can save.
The 50/30/20 Rule as a Starting Point
A widely-used budgeting framework divides net monthly income into three categories: 50% for needs (essential fixed costs — rent/mortgage, utilities, food, insurance, minimum debt payments); 30% for wants (lifestyle spending — restaurants, entertainment, subscriptions, holidays); and 20% for savings and debt repayment above minimum. UK housing costs often push the needs percentage higher, requiring adjustments to other categories. The most valuable insight from any budget is the gap between income and essential outgoings — the maximum available for savings and discretionary spending.
Common Budget Blind Spots
Annual or irregular expenses are the most frequently missed items: car insurance, road tax, home insurance, service contracts, and annual subscriptions. Divide each annual cost by 12 and include it as a monthly provision to avoid being caught short. Use our Energy Bill Calculator to model your monthly energy costs at current Ofgem rates, and our Council Tax Calculator to estimate your council tax as a monthly provision.
Frequently Asked Questions
All regular income (salary after tax, benefits, rental income), all fixed outgoings (mortgage/rent, utilities, insurances, subscriptions, minimum debt payments), and all variable spending categories (food, transport, leisure).
Zero-based budgeting allocates every pound of income to a specific category until the budget reaches zero — meaning income minus all categories equals zero. Nothing is left unallocated; every pound has a job.
A clear budget identifies surplus income available for debt repayment beyond the minimum. Our Credit Card Repayment Calculator shows how any fixed monthly payment compares to minimum repayments over the full payoff period.
Monthly review catches problems early. A full annual review — usually after the new tax year in April — updates all income figures for salary changes and benefit uprating. Major life events each require an immediate budget reassessment.
Absolutely. Identifying the monthly surplus available for saving is the first step. Our Mortgage Deposit Calculator shows how long it takes to save any deposit target at your available monthly saving rate.
Start with your net monthly take-home pay. Work through each expense category systematically: housing (mortgage or rent, ground rent, service charge), utilities (energy, water, council tax, broadband, TV licence), food, transport (fuel, public transport, parking), debt repayments, insurance premiums, subscriptions, childcare, and discretionary spending (eating out, entertainment, clothing, hobbies). Use bank statement categories for the past three months rather than estimates — actual spending reveals patterns that estimates miss. The results show your monthly surplus or deficit and spending by category as a percentage of income. If the result shows a deficit, identify which categories offer the most practical scope for reduction. Fixed committed costs require longer-term solutions; discretionary spending is the quickest lever.
