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.
The biggest savings come not from giving up coffee but from reviewing a few regular costs: groceries, impulse purchases, subscriptions, electricity, mobile plans and bank fees. In our example for a Ukrainian household spending about UAH 30,000 a month, these steps free up around UAH 2,924 a month, or UAH 35,088 a year, without giving up what really matters. Saved at the average deposit rate, that adds up to about UAH 234,977 in 5 years.
Tips like «skip the coffee» are irritating and rarely change anything: they take away pleasure and deliver little. Real savings come where money goes out regularly and unnoticed: automatic payments, shopping habits and tariffs nobody has reviewed for years. Set these up once and you save every month without constant effort.
The principle is simple: first cut what you will not notice, and only then think about what you would actually have to change in your life.
Open your bank card statement for the last three months. Most banking apps already group spending by category. Look for three things:
If you do not have a budget system yet, start with a simple split of your income: how to do it is explained in our article on the 50/30/20 rule.
| What to change | Per month | Per year |
|---|---|---|
| Groceries with a list and a weekly menu (10% of UAH 10,000) | UAH 1,000 | UAH 12,000 |
| A pause before unplanned purchases | UAH 800 | UAH 9,600 |
| Cancel 2-3 unneeded subscriptions | UAH 450 | UAH 5,400 |
| Shift 150 kWh to the night tariff | UAH 324 | UAH 3,888 |
| Mobile plans matched to real use, 2 numbers | UAH 200 | UAH 2,400 |
| Bank fees and cashback | UAH 150 | UAH 1,800 |
| Total | UAH 2,924 | UAH 35,088 |
The amounts are illustrative: yours will differ. But the pattern is usually similar: groceries and impulse purchases matter most, not the subscriptions people write about most often.
Groceries are one of the biggest spending categories, and planning has the biggest effect here.
Put off any unplanned purchase above a threshold you choose, say UAH 1,000, for 2-3 days. If you still need it after the pause, buy it with a clear head. Some wants disappear on their own in that time. Technical steps help too: delete saved cards from online shops and turn off discount newsletters.
Be especially careful with «pay in instalments»: it makes an expensive purchase feel lighter, and the fee often hides in the monthly payments. How to work out its real cost is explained in our article on the true cost of credit.
Find every regular payment in your statement and ask of each: did I use it last month? Also check subscriptions in the App Store and Google Play: they often renew automatically after a free trial. Anything you use rarely is cheaper to pay for one-off when you need it.
From 1 November 2026, Ukrainian households pay UAH 4.32 per kWh. Owners of two-zone meters pay with a 0.5 coefficient from 23:00 to 07:00, that is UAH 2.16. Every kilowatt-hour moved to the night saves UAH 2.16.
Those who can run a water heater, washing machine or dishwasher at night, or charge batteries, gain the most. A two-zone meter is installed by the distribution system operator and switching has a cost, so first work out how many kilowatt-hours you can really move.
Check in your operator's app how many gigabytes and minutes you actually use. Often a plan was chosen years ago and is either more expensive than current offers or includes far more than you need. Family plans and «internet plus mobile» bundles can also be cheaper than separate ones.
Saved money left on your card usually gets spent without you noticing. So set up an automatic transfer to a separate account on payday: first you «pay yourself», then you live on the rest.
You can work out your own case in the compound interest calculator. For money you will not need within a year, government bonds pay more because the income is tax-free: how to buy them is explained in our guide on how to buy OVDP.
If the savings are meant for a specific goal such as a car or a renovation, work out the monthly amount for the purchase date allowing for inflation: the article “How to save for a big purchase” shows how.
