How to make a personal budget: the 50/30/20 rule and alternatives
We walk through the rule on a UAH 30,000 income and three alternatives for people who find 50/30/20 a poor fit.
You track expenses to see where your money really goes and to find money for your goals: after 2 or 3 months of tracking you usually spot a few categories where money disappears unnoticed. The easiest way is to update a spreadsheet once a week from your banking app statement. Below are three methods with their pros and cons, the rules that make tracking stick, and a free WM² template for Excel and Google Sheets with formulas and a 50/30/20 check.
Most people know their income to the hryvnia but their spending only roughly. That "roughly" is where the money hides that later is missing for an emergency fund, a holiday or a down payment. Tracking gives you four things:
According to the financial literacy survey the NBU and USAID ran in 2021, 68% of Ukrainians plan their household income and spending, yet only 41% have long-term financial goals. Tracking bridges the two: without it a plan stays a wish.
| Method | Pros | Cons | Best for |
|---|---|---|---|
| Analytics in your banking app | Nothing to enter, categories assigned automatically | Misses cash and other banks, categories are often wrong, no planning | People who pay with one card and want a rough picture |
| Spreadsheet (Excel, Google Sheets) | Full control, your own categories, all cards and cash in one place, yearly totals | You have to enter data, at least once a week | People with several cards, a family budget or specific goals |
| Dedicated budgeting app | Easy entry on the phone, charts | Paid features, your financial data in a third-party service, history is hard to move | People who want to log each purchase right after paying |
A combination works best: the banking app as the data source and a spreadsheet for totals. Once a week you open the statement and move the last 7 days into the spreadsheet, grouping small purchases of one category into a single row. It takes 10 to 15 minutes.
You can start from the history you already have. Download statements for the last 2 or 3 months from all your cards: most banking apps offer PDF, Excel or CSV in the statements section. Then, in one evening:
This snapshot almost always surprises: groceries, food delivery, taxis and small online purchases are the usual underestimates. Cash will not show up in the statement, so put withdrawals in a separate "Cash" row, and from next week note what the cash goes on.
We made a spreadsheet template that does the maths for you: you only enter the date, amount and category. The Excel file opens in Excel, Google Sheets (via Drive or File → Import), LibreOffice and Numbers, with no macros and no ads.

What is inside:
Yellow cells are for your data; the rest hold formulas. Delete the grey example rows when you start your own tracking.
You need enough categories to see where money leaks, but not so many that each purchase needs thought. 12 to 20 is about right. In the template they are split into three types, as in the 50/30/20 rule:
| Type | Categories |
|---|---|
| Needs | Housing (rent, mortgage), utilities, groceries, transport, phone and internet, health, children, minimum loan payments |
| Wants | Cafes and food delivery, entertainment and hobbies, clothes and shopping, subscriptions, travel, gifts, other |
| Savings and debt | Emergency fund, goals and investments, extra debt repayment |
A few rules that make categories work:
How to set your own shares and what to do if needs take more than half your income is explained in "The 50/30/20 rule".
The most common reason people quit tracking is a month when insurance, a car repair and children's activities all fall due at once. It feels as if the budget does not work, although these costs were known in advance. The fix is a list of yearly payments and putting aside 1/12 of each every month.
| Irregular expense | Per year, UAH | Put aside monthly, UAH |
|---|---|---|
| Car insurance | 9,600 | 800 |
| Car servicing | 6,000 | 500 |
| Holiday and birthday gifts | 8,000 | 667 |
| Children's activities and school costs | 7,200 | 600 |
| Holiday | 36,000 | 3,000 |
| Dentist and check-ups | 6,000 | 500 |
| Total | 72,800 | 6,067 |
In this illustrative example irregular costs add over UAH 6,000 to the monthly budget, although no single month "shows" them. Keep this money apart from your emergency fund: the fund is for the unpredictable, while insurance and holidays are entirely predictable. A separate savings account or a "jar" in your banking app works well.
In the template, record such payments in the month you actually pay, in the matching category. The Monthly average column on the Summary sheet then shows what they cost per month.
Tracking shows the past; limits steer the future. Once you have 2 or 3 months of averages, set a limit for each wants category. Needs are usually not capped; they are reduced through decisions such as a different tariff or different housing.
Keep the limit realistic: 20 to 30% below the average. A limit at half the average rarely holds. If cafes and delivery average UAH 3,800, a UAH 2,500 limit is noticeable but achievable. For day-to-day control, turn it into a weekly figure: 2,500 × 12 / 52 ≈ UAH 577 a week. Then the weekly review shows whether you are on track before the month ends.
Another approach that works is a separate card for wants. On payday the monthly limit for cafes, entertainment and shopping goes to that card, while needs and savings are paid from the main card. When the card runs out, the limit is used up, and there is nothing else to count.
The first month of tracking is almost always inaccurate: something is forgotten, something lands in the wrong category. Do not draw conclusions straight away. After 2 or 3 months the picture settles, and you can ask four questions:
Needs at 65% in this example are a signal that the big reserve lies in bigger decisions: housing costs, transport, loans. Cafes will only give part of it. How to cut costs without feeling poor is covered in "How to save money".
With a shared budget, tracking removes most money arguments: instead of "you spent it all again" there are numbers both of you can see. First agree on how you split costs. The three most common models:
| Model | How it works | When it fits |
|---|---|---|
| Everything shared | All income goes into one pot, all spending comes out of it, one spreadsheet | Long relationships, shared goals, similar views on spending |
| In proportion to income | Each partner pays a share of joint costs that matches their income; the rest is personal money | A noticeable income gap |
| Fixed contribution | Each puts the same amount into the joint pot; the rest is personal | Similar incomes, a wish for more personal freedom |
For joint tracking, upload the template to Google Sheets and give your partner edit access: you can both add expenses from your phones and see one total. Use the Note column to say who paid. Fifteen minutes together over the monthly summary does more than any argument about single purchases.
If you have teenagers, show them the month's summary: what housing, groceries and their activities cost. It is one of the clearest money lessons there is.
With credit cards it is easy to count spending twice: first the purchase, then the repayment. The rule is simple: record the purchase in its category on the day you buy, and do not record the card repayment as spending, because it is a transfer between your own accounts. Interest and fees, if you missed the grace period, go separately into Minimum loan payments.
With instalment plans it is the other way round: recording monthly payments is more convenient, because then tracking shows the real load on each month's budget. The key is to pick one method and stick with it. Before taking a new instalment plan, check how many monthly payments you already have: if together with a mortgage or loans they exceed 30 to 40% of income, new debt is a risk.
Sole proprietors, freelancers and anyone whose income varies month to month need tracking even more, but it works a little differently:
Tracking answers "where does the money go". The next step is deciding where it should go: which goals, by when, how much to put aside each month and in what. After 3 months of tracking you have all the numbers for this: average spending, the real surplus, an emergency fund target of 3 to 6 months. How to turn that into a one-page plan is explained step by step in "A personal financial plan".
