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.
A personal financial plan is a written answer to three questions: where you are now, what you want to achieve and what you do each month to get there. It is built in 7 steps: a financial snapshot, goals with amounts and deadlines, a budget, an emergency fund, a debt plan, protection against major risks, and investing and retirement. One evening is enough for a first version, and after that the plan is reviewed once a year and after major life changes.
A budget answers the question of where your money goes this month. A plan answers the question of where it should take you in a year, five years and twenty years. A budget without a plan easily turns into tracking spending for its own sake, and a plan without a budget into a wish list.
According to a financial literacy survey of 2,040 Ukrainian adults carried out by the NBU and USAID in 2021, 68% plan household income and expenses, but only 41% set long-term financial goals and work towards them. Meanwhile 41% of respondents, if they lost their main income, could cover expenses for no more than a month, and only 7% for more than six months. These figures are from before the full-scale war, and since 2022 many families' safety margin has become thinner, so a plan matters today more than ever.
A plan does not need to be a complex document. One page of figures that you review once a year works better than a perfect spreadsheet abandoned after a month.
Before planning a route, you need to know the starting point. Write down four lists:
The difference between assets and debts is your net worth. It is what shows your financial position, while income can be misleading: someone with a high salary and large loans may have a lower net worth than someone on a modest income with no debts.
Write this snapshot down with a date. A year later you will compare it with a new one, and that will be the most honest assessment of whether the plan is working.
You do not need to record every coffee for a month. Take statements from all your cards for the last 2-3 months, add an estimate of cash spending, and split everything into a few categories:
| Category | What it includes |
|---|---|
| Housing | Rent or mortgage, utilities, internet |
| Food | Groceries, household supplies; cafes and delivery separately |
| Transport | Fares, fuel, car insurance and servicing |
| Debts | Loan and instalment payments |
| Children | Nursery, school, clubs, clothes |
| Health | Medicines, doctors, tests |
| Wants | Cafes, entertainment, subscriptions, shopping, holidays |
Usually at this stage you can already see 2-3 categories where money "leaks" unnoticed: food delivery, subscriptions, small in-app purchases. That is your first reserve for goals.
"I want to save" is not a goal. A goal has three parameters: what exactly, how much it costs and when. Split your goals by time horizon, because the horizon decides where to keep the money:
| Horizon | Examples | Where to keep the money |
|---|---|---|
| Up to 1 year | A holiday, redecorating a room, appliances | A card paying interest on the balance, a short deposit |
| 1-5 years | A car, a housing down payment, education | Deposits, government bonds maturing before the goal date |
| Over 5 years | Children's education, your own business, retirement | A portfolio of government bonds, equity funds and a small share of gold |
The main mistake with goals is counting them in today's prices. Over 5 years at 10% annual inflation, prices rise about 1.61 times.
The calculation is illustrative: neither inflation nor rates will stay constant for 5 years. That is exactly why the plan is reviewed every year. You can plug in your own amounts and terms in the compound interest calculator.
Rank your goals by priority. If there is not enough money for all of them, the emergency fund and paying off expensive debt come first, then goals with the nearest deadline, and only then everything else.
In a plan, the budget has one job: to leave an amount each month that goes to your goals. The simplest framework is the 50/30/20 rule: half of income on essentials, 30% on wants and 20% on savings and debt repayment. How to work out your own shares and what to do if essentials exceed half your income is explained in our article on the 50/30/20 rule.
Three techniques that make a budget resilient:
For sole proprietors, freelancers and anyone whose income changes month to month, a classic "payday" budget does not work. A workable scheme:
An emergency fund is a reserve covering 3-6 months of essential expenses in case of lost income, illness or urgent repairs. It comes first, before any investing: without it, the first setback will force you to borrow or sell investments at a bad moment.
The size, where to keep it and the order of building it are covered in detail in our article on an emergency fund.
Debts in a plan fall into two groups. Expensive ones, such as credit cards after the grace period, consumer loans and payday loans, should be paid off as fast as possible: no reliable investment returns more than their rate. Cheap ones, such as a subsidised mortgage or a low-rate loan, can be repaid on schedule.
For several expensive debts there are two approaches:
Both work as long as new debts do not appear at the same time. So while repaying, it is worth blocking credit limits on cards and turning down new instalment plans.
A rule for new borrowing in your plan: borrowing can make sense for things that gain value or bring income (housing, education, a tool for work), and is best avoided for things that lose value or disappear (gadgets, holidays, clothes).
An emergency fund covers small and medium setbacks. But some events can wreck a plan entirely: serious illness, loss of ability to work, the death of an earner, destruction of a home. They need separate protection.
Protection earns nothing, which is why it gets put off. But a plan in which one event can wipe out 10 years of savings is a plan without a foundation.
Once you have an emergency fund, no expensive debt and short-term goals funded, money for long-term goals can be invested. The order is simple: the further away the goal, the larger the share that can be held in equity funds; the closer, the larger the share in government bonds and deposits.
Someone earning the national average salary with 35 years of insurance record who retires in 2026 gets about UAH 6,119 by the formula. That is roughly 24% of the average salary of UAH 25,002. In other words, the state pension replaces only a quarter of usual income, and you will have to provide the rest yourself. You can estimate your own pension in the retirement pension calculator.
Suppose you want an extra UAH 10,000 a month on top of the state pension, in today's prices. By the 4% rule this needs capital of 25 years' worth: 10,000 × 12 × 25 = UAH 3,000,000. If investments return 3% a year above inflation, the monthly contribution depends on when you start:
| Years to retirement | Monthly contribution in today's prices |
|---|---|
| 30 years | UAH 5,184 |
| 20 years | UAH 9,178 |
| 10 years | UAH 21,513 |
Starting 10 years earlier means saving almost half as much. Contributions are raised each year by inflation so that they stay the same in real terms. How to split this money between instruments and review the proportions is covered in our article on an investment portfolio for beginners.
A couple with a child earn UAH 50,000 a month together after tax. Essential expenses are UAH 26,000, wants UAH 14,000. That leaves UAH 10,000, or 20% of income, for goals and debts. They have UAH 30,000 of savings and a credit card debt of UAH 20,000.
In a family plan it is also worth agreeing on three things: which goals are shared and which are personal; which spouse is responsible for which payments; and how much each can spend without consulting the other. Transparency matters more than equal contributions: a plan only one spouse knows about rarely gets followed.
The result of the seven steps should fit on one page. Here is a template you can copy and fill in:
Change the plan when your circumstances change; the news is no reason to. A market fall or a jump in the exchange rate does not change long-term goals. It is only a reason to check whether too much money for short-term goals sits in risky instruments.
