Monthly Budget Planner 2026-27
Take control of your money — see where it all goes.
Plan your monthly budget in United Kingdom. Enter your take-home income and expenses across housing, food, transport, utilities, and lifestyle. See your monthly surplus or deficit and whether you are following the 50/30/20 rule.
Results are estimates based on your inputs. Actual expenses vary by location and lifestyle.
Track monthly income vs expenses to find your surplus
Income minus expenses
A budget calculates your monthly surplus (income minus total expenses). Positive surplus means you are living within your means and can save or invest. A deficit means expenses exceed income — identify and cut discretionary spending. Update monthly and compare over time.
Allocate income across needs, wants, and savings
Three simple buckets
Needs (50%): Housing, groceries, transport, utilities, insurance, minimum debt payments — things you genuinely cannot live without. Wants (30%): Dining out, entertainment, streaming, clothes beyond basics. Savings (20%): Emergency fund, ISA contributions, debt extra payments.
When housing alone takes 40%+ of income (common in London or major cities), adapt: cut wants aggressively or increase income before increasing savings.
Typical UK monthly household budget benchmarks
The Office for National Statistics (ONS) publishes an annual Family Spending survey that tracks average weekly household expenditure by region and household composition. The figures below are derived from the latest ONS release and show indicative monthly essential spend — housing, food, transport, utilities, and council tax combined.
Essential monthly outgoings by region
| Region | Single adult | Couple | Family of 4 |
|---|---|---|---|
| London | £2,200 | £3,400 | £5,200 |
| South East | £1,750 | £2,700 | £4,300 |
| East of England | £1,600 | £2,500 | £4,000 |
| Midlands | £1,350 | £2,100 | £3,400 |
| North West & Yorkshire | £1,250 | £1,950 | £3,150 |
| North East | £1,150 | £1,800 | £2,950 |
| Scotland | £1,300 | £2,000 | £3,250 |
| Wales | £1,250 | £1,950 | £3,150 |
What is included
Figures assume median private rent or mortgage interest, Ofgem energy price cap (dual fuel ~£1,700/yr), a Band C–D council tax, a weekly Aldi/Lidl grocery shop, and public transport or a modest car budget. They exclude childcare, holidays, and discretionary spending. The ONS Family Spending in the UK bulletin remains the source of record for cross-regional comparisons.
Adjustments to apply
London renters should add £300–£600/month over the table for housing in Zones 1–3. Families with pre-school children need to layer nursery or childminder costs (£1,100–£1,800/month per child in London, £700–£1,100 elsewhere per the Coram Family and Childcare survey). If you drive rather than use public transport, add £150–£250/month for fuel, insurance, and VED once annualised.
Budgeting methods: 50/30/20 vs zero-based vs envelope vs pay-yourself-first
No single budgeting method suits every household. The right framework depends on how predictable your income is, how tempted you are by discretionary spending, and how much time you want to spend reviewing finances each month.
50/30/20 rule
Split take-home pay into 50% needs, 30% wants, and 20% savings or debt repayment. Popularised by US Senator Elizabeth Warren but widely used by MoneyHelper and the Money and Pensions Service in the UK. Works well for median UK earners outside London. Weakness: unrealistic where housing alone takes 40%+ of net pay (Greater London, Bristol, Brighton) — a 60/20/20 or 60/25/15 split is often more honest.
Zero-based budgeting
Every pound of income is assigned a job before the month starts — £1,200 rent, £400 groceries, £250 ISA, and so on until income minus allocations equals zero. Used by YNAB (You Need A Budget, £90/year) and Monarch. Strong control but requires 20–30 minutes a week to maintain. Best for people digging out of debt or trying to save a house deposit in under three years.
Envelope method
Allocate cash or virtual "pots" to each category — groceries, petrol, takeaway, gifts. Once an envelope is empty, spending in that category stops until next payday. Monzo "Pots", Starling "Spaces", and Revolut "Vaults" replicate the analogue method digitally, and most now support scheduled transfers into named pots on payday. Useful for controlling variable categories like dining and clothes.
Pay yourself first
Move savings out of your current account the day your salary lands — into a Cash ISA, Stocks & Shares ISA, or pension — then live on what remains. Set up a UK standing order for the day after payday to the receiving account. Because HMRC's £20,000 annual ISA allowance cannot be carried forward, automating £1,667/month fills it over the tax year without requiring willpower. Auto-enrolment pension contributions already work this way at the 5% employee minimum.
Which method fits you?
| Method | Time per week | Best for | Automation tool |
|---|---|---|---|
| 50/30/20 | ~5 min | Stable salary, low debt | Monzo Summary, Starling Insights |
| Zero-based | ~25 min | Clearing debt, saving deposit | YNAB, Monarch, Emma |
| Envelope / pots | ~10 min | Overspending on variable categories | Monzo Pots, Starling Spaces |
| Pay yourself first | ~2 min | Consistent income, ISA/pension focus | UK standing order, Vanguard/Trading 212 auto-invest |
Frequently askedFrequently asked questions
How do I fix a budget deficit?
Three levers: (1) Reduce fixed costs — housing is the biggest opportunity, consider moving or taking on a flatmate. (2) Cut variable spending — dining, entertainment, and subscriptions are the easiest to reduce immediately. (3) Increase income — overtime, side income, or requesting a pay review. Even small wins compound: £200/month saved = £2,400/year = emergency fund in 5 months.
How much should I save each month in the UK?
UK guidance: 10–20% of take-home is the target. At minimum: enough to build a 3-month emergency fund (e.g. £10,000 if expenses are £3,333/month). Then maximise ISA (£20,000/year allowance), then pension contributions above auto-enrolment minimum (3% employee).

Select the question that matches where you are right now.
Your result shows the projected growth or return based on the rate, contribution, and time period you entered — using standard compound or simple interest formulas.
Use this to set savings targets, compare investment options, or understand the impact of starting earlier. Adjust the rate and timeframe to model optimistic and conservative scenarios.
Not a guaranteed return. Actual investment outcomes depend on market conditions, fees, taxes, and timing that cannot be predicted with certainty.
Uses standard financial formulas with the inputs you provided. All calculations run in your browser — no data is sent to any server.
Savings and investment results are dominated by three factors: the rate of return, the time horizon, and regular contributions. Compounding amplifies all three over time.
Returns on returns accelerate growth over time. The difference between 5% and 7% over 20 years is much larger than the 2% gap suggests — compounding is non-linear.
Adding even small regular amounts dramatically increases the final balance. £100/week invested at 7% for 20 years grows to over £110,000 in contributions and £110,000+ in returns.
Starting 5 years earlier often produces a larger final balance than doubling your contribution rate. Time is the most powerful variable in savings calculations.
To improve your savings outcome, focus on starting earlier, increasing contributions, and minimising fees and tax drag on returns.
Starting with a small amount today and increasing over time beats waiting to start with a larger amount. Time in the market matters more than timing the market.
A 1% annual fee on a £100k balance costs £1,000/year and compounds against you. Compare fee structures across savings and investment products.
Super, offset accounts, and tax-free thresholds reduce the drag of tax on your returns — letting more of the growth compound for you.
