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.
An emergency fund is a cash reserve covering 3-6 months of your essential expenses that you touch only if you lose income, fall ill or face an unexpected bill. Keep it where the money is protected and available within a day or two: a separate savings account with interest, a deposit that allows early withdrawal, partly in foreign currency. The longer-term part can go into government bonds.
Most money problems start with unplanned events, not big mistakes: a layoff, an illness, a broken car, a move. Without a reserve for such moments you end up taking a loan, borrowing from friends or selling investments at the worst possible time.
An emergency fund breaks that chain. It gives you time to find a new job calmly instead of grabbing the first offer, and it keeps small crises from eating into your long-term savings. That is why financial advisers suggest building the fund first and investing second.
The standard advice is 3 to 6 months of essential expenses. Expenses, not income, and only the ones you cannot skip: housing, food, utilities, transport, phone, medicine and loan payments.
Where you land in that range depends on how stable your income is and how many people rely on it.
| Your situation | Reserve |
|---|---|
| Stable job, two incomes in the household, no children | 3 months |
| One income in the household, or children or other dependants | 4-6 months |
| Sole proprietor, freelancer, business owner, seasonal or piece-rate pay | 6 months or more |
| Unstable industry or high risk of losing your job | 6-12 months |
Take your card statements for the last 2-3 months and list only the essential spending. Leave out cafes, entertainment and feel-good shopping: in a crisis month you would cut them anyway.
Don't let the number scare you. Nobody builds the fund in a month. What matters is having a target and moving towards it regularly.
The fund has three requirements, in this order: safety, access, return. The money must be protected, you must be able to get it within a day or two, and only then would you like it to earn a little and hold its value.
The most convenient option for the main part. The money is available instantly and the bank pays interest on the balance. Make sure it is a separate account, not the same card you pay with every day: that way there is less temptation to spend it.
Rates are usually higher than on a savings account. Read the terms carefully, though: on some deposits, if you close early, interest is recalculated at a minimal rate or not paid at all. For an emergency fund, use only deposits that let you take the money out without losing the principal. The deposit calculator shows the after-tax income for your amount and term.
If a significant share of your expenses is tied to the exchange rate (rent in dollars, imported medicine, plans to move abroad), it makes sense to hold part of the fund in foreign currency. This protects you against a sharp devaluation of the hryvnia. Currency accounts usually pay little or nothing, though, so keeping the whole fund in currency is not ideal either.
Ukrainian domestic government bonds (OVDP) are debt securities issued by the Ministry of Finance. You can buy them through banks and brokers, and the yield is often higher than on deposits. They suit the second layer of the fund, not money you may need tomorrow: you can sell bonds before maturity, but the price at that moment may be lower than what you paid. A sensible setup is 1-2 months of expenses in an account and the rest in bonds with different maturities.
| Option | Access | Return | Which part |
|---|---|---|---|
| Savings account | instant | moderate | core, first 1-2 months |
| Deposit with early withdrawal | 1-2 days | higher | middle part |
| Foreign currency | instant | low | protection from devaluation |
| Government bonds | a few days, price risk | often the highest | longer part, 3+ months |
Deposits of individuals in banks that participate in Ukraine's Deposit Guarantee Fund (FGVFO) are protected: if a bank fails, the Fund repays the deposit up to the guaranteed amount. That amount has changed over the years, so check the current limit on the FGVFO website before placing large sums.
If you have debts, the obvious question is whether to put every spare hryvnia into the loan instead. The answer depends on the rate, but the basic rule is: first a minimal fund of 1 month of expenses, then expensive debts, then the full fund.
The logic is simple. With no reserve at all, the first unexpected expense will push you into a new loan, often an even more expensive one. At the same time, keeping a large fund at 10-14% a year while paying 40% on a credit card is a losing deal: the gap in rates costs more than the peace of mind is worth. Once the expensive debts are closed, the same monthly amounts that went into repayments can go into finishing the fund. How to calculate total interest and how much early repayment saves is explained in our article on annuity and equal principal payments.
Once the fund is in place, the next step is to put the rest of your savings to work. How to do that is covered in our article on compound interest.
