If you’ve tried budgeting apps and still feel like your money “disappears,” you’re not failing—your system is. In 2026, most people don’t need more tracking; they need a plan they can actually follow in real life.
This simple spreadsheet method gives you:
- A clear monthly plan (bills + goals)
- Weekly spending limits (so you don’t blow the budget early)
- A quick tracker that takes 2 minutes a day
By the end of this post, you’ll have a spreadsheet structure you can copy into Google Sheets or Excel, plus 3 rules that keep the budget working even when life is busy.
Key Takeaways (quick summary)

Why a spreadsheet beats most budgeting apps in 2026
Budgeting apps can be useful, but many people quit because they:
- Categorise spending wrong (and you waste time correcting it)
- Show you charts after you’ve overspent
- Hide annual bills until they hit
- Don’t match your pay cycle (weekly, fortnightly, monthly)
- Don’t give you a clear “safe to spend this week” number
A spreadsheet wins because it’s a plan + a decision tool:
- You set limits before spending happens
- You see what’s coming (bills, subscriptions, annual costs)
- You can adapt it to your real paydays
The Simple Spreadsheet Method (in one sentence)
Monthly Plan (bills + goals) → Weekly Limits (real-life guardrails) → Tracker (keep control).
That’s it. Three tabs. No complicated dashboards.
The 3 rules that make this method work
Rule 1: Pay yourself first (even if it’s small)
Add savings and sinking funds into your plan before lifestyle spending.
Start small:
- £10–£25 per payday is enough to build the habit
- Increase later when your system feels stable
Why it works: saving becomes a “bill” you always pay.
Rule 2: Weekly limits beat monthly motivation
Most budgets fail because people try to “be good” for 30 days.
Instead, give yourself weekly caps for:
- Groceries
- Transport
- Fun/eating out
- Miscellaneous
Example: If variable spending is £600/month → £150/week.
Weekly limits stop week-one blowouts.
Rule 3: Track only what matters (don’t over-categorise)
You don’t need 30 categories. You need consistency.
Use 6–10 categories max, for example:
- Fixed bills
- Groceries
- Transport
- Fun
- Household
- Health/Beauty
- Savings/Sinking funds
- Other
Why it works: less friction = you keep doing it.
The Spreadsheet Template (copy this structure)
Tab 1: Monthly Plan
Create columns like:
- Category
- Item
- Due date
- Planned (£)
- Actual (£)
- Notes
Use sections like:
Income
- Salary
- Side income
- Other
Fixed Bills
- Rent/mortgage
- Council tax
- Energy
- Water
- Broadband/mobile
- Insurance
- Subscriptions
Variable Essentials
- Groceries
- Transport
- Household
Lifestyle
- Eating out
- Shopping
- Entertainment
Savings + Sinking Funds
- Emergency fund
- Holiday fund
- Car/repairs
- Birthdays/Christmas
- Annual bills buffer
Top-of-sheet totals to add:
- Total income
- Total planned spending
- Planned left over (Income − Spending)
Goal: aim for £0 to £50 left over (so your plan is realistic and complete).
Tab 2: Weekly Limits
Create columns like:
- Week
- Groceries
- Transport
- Fun
- Misc
- Weekly total
Set weekly limits by dividing your monthly variable spending by 4 (or match your pay cycle).
Tip: Increase “Misc” if you keep breaking your budget. It’s better to plan for real life than pretend.
Tab 3: Tracker (Daily Spending)
Create columns:
- Date
- Description
- Category
- Amount (£)
- Paid by (card/cash)
- Notes
This is the only part you update daily (2 minutes).
Bills can stay in the Monthly Plan.
Set it up in 20 minutes (step-by-step)
- Write your monthly income (after tax).
- List all fixed bills (everything that must be paid).
- Add sinking funds for irregular costs (annual, seasonal, surprise).
- Set weekly limits for groceries/transport/fun/misc.
- Track spending daily or every 2 days (keep it simple).
The sinking funds trick (how to stop budget surprises)
Sinking funds are small monthly amounts for costs that aren’t monthly.
Examples:
- Car service: £300/year → £25/month
- Christmas: £600 → £50/month
- Birthdays: £240 → £20/month
- Annual insurance: £360 → £30/month
This is what turns budgeting into calm money management.
Example budget you can copy (realistic numbers)
Let’s say monthly income is £2,200.
- Fixed bills: £1,350
- Savings + sinking funds: £250
- Variable spending left: £600
Weekly limits (600 ÷ 4 = 150/week):
- Groceries: £80
- Transport: £25
- Fun: £30
- Misc: £15
Total: £150/week
Common mistakes (and fast fixes)
Mistake: You forget to track.
Fix: Pick one daily moment (after dinner) → 2-minute update.
Mistake: “Misc” is too small.
Fix: Increase misc and reduce fun/shopping slightly.
Mistake: Annual costs aren’t included.
Fix: Add sinking funds today—even small ones.
Mistake: You keep changing your system.
Fix: Run it for 30 days, then tweak once.
The 5-minute weekly money reset (do this once a week)
- Check your running balance
- Update weekly totals
- Roll leftover “fun money” forward (or add to savings)
- Look ahead for upcoming costs
- Adjust next week’s limits if needed
Final takeaway
If apps haven’t worked for you, it’s not because you lack discipline. Most people do better with a system that creates clear weekly boundaries and plans for real life.
A spreadsheet wins because it’s flexible, honest, and simple enough to stick to.
Next step: Create the 3 tabs today and try it for 7 days. Your money will feel clearer almost immediately.
FAQs (add these near the bottom for SEO)
1) Is spreadsheet budgeting better than an app?
For many people, yes—because spreadsheets help you plan spending before it happens, not just track after. Apps can be great for automation, but a spreadsheet gives clearer control over weekly limits and irregular costs.
2) How many categories should I use?
Keep it simple: 6–10 categories. Too many categories increases effort and makes you quit. Focus on the categories that actually affect your decisions: groceries, transport, fun, bills, savings, and misc.
3) What if my income changes each month?
Use a “baseline” plan based on your lowest expected income. When you earn more, assign the extra to priorities in order: bills buffer → sinking funds → emergency fund → goals.
4) What’s the easiest way to start if I’m overwhelmed?
Start with just two things:
- Fixed bills (monthly plan)
- Weekly limit for groceries + fun
Track only those for 7 days. Then expand.
5) What are sinking funds and do I really need them?
Sinking funds are small monthly amounts saved for non-monthly costs (car repairs, birthdays, annual bills). They prevent “surprise” expenses from breaking your budget and are one of the biggest differences between stress and stability.
6) How often should I update my spreadsheet?
Daily is ideal (2 minutes), but every 2–3 days works if you stay consistent. Do a weekly reset once a week for 5 minutes to keep everything on track.
