Passive Income: How to Count Payouts, Costs and Risks

Passive income is money your existing investments pay you: interest on savings, bond coupons, dividends, fund distributions and rent. The rate in an advert or a contract is almost never the amount you can spend. Taxes, costs, the payment calendar and the chance that a payout shrinks all sit in between. This article shows how to work out an honest monthly figure from your own assets, walks through a worked example to show where the money goes, and tests the plan against a bad year.

Passive Income, Side Work and Selling Assets: Three Different Flows

"Passive" is often used for anything that is not a salary. For planning, it helps to separate three flows of money, because they behave differently.

Passive income is what an asset pays you while you keep the asset. A savings account pays interest, a bond pays coupons, a share pays dividends, a flat pays rent. The capital does the work, and you do not sell any of it to get the cash.

Side work is income from your time: freelancing, a blog, an online shop, tutoring. Even when it is largely automated, it depends on your effort and stops when you stop. This article leaves it out.

Selling an asset is a one-off inflow. Selling some shares or a property brings in cash, but it also shrinks the capital that would otherwise keep paying you. Living partly off sales of capital is a perfectly valid strategy, but it answers a different question: how much capital you need and how long it will last.

Which Payouts Exist and What Changes Them

Every source has someone who decides the payout, its own calendar and its own reasons to change.

The main lesson of the table: the most predictable income is income fixed for a term, and that is exactly why it protects you least against inflation. A bond coupon does not rise with prices, and a deposit may roll over at a lower rate. Dividends and rents can grow, but they can also disappear. How shares and dividends and bonds work is covered in separate Basics articles.

From Gross Income to Money You Can Spend

The gross payout is what the bank, the issuer or the tenant pays. Money you can spend is what is left after three deductions.

Taxes

Tax rules depend on your country of tax residence, and different kinds of income are often taxed at different rates. Interest, dividends and rent may each have their own rate, some government bonds are tax-free, and some countries tax rent on the gross amount while others let you deduct expenses first. Income from abroad may also be taxed at source by the country where the asset is registered. Look up the rules that apply to you before you trust any after-tax figure.

Fees and product costs

A fund takes its running costs out of its holdings' income before it distributes anything, so the announced distribution is already net of them. Your broker may still charge account, custody or transfer fees, and a currency conversion can take another slice. Buying bonds through an intermediary can include a markup that lowers your yield. Withdrawing a term deposit early often means giving up part of the interest.

Upkeep costs

Property carries the most: empty months, repairs and replacing appliances, insurance, utility bills while the flat is empty, letting-agent fees and property taxes. None of this shows up in an advert that says "rent: 1,250 a month", yet every year it takes a share of the rent.

A Worked Example: Capital, Regularity and Liquidity

All numbers below are illustrative: they are not current market rates or a forecast, and the tax rates are assumptions for the example, not the rules of any particular country. Take someone with 400,000 dollars spread across four sources.

The flat assumes one empty month a year, so it collects 11 months of rent, $13,750 instead of $15,000. The $3,000 covers assumed repairs, insurance and utilities.

The result: $12,825 a year, or about $1,069 a month on average. Of the $20,500 of gross payouts the sources promise on paper (with rent for all 12 months), about 63% reaches you. The net yield on the whole capital is about 3.2% a year, even though the individual rates in the table looked like 4%, 5% and a 6% gross rental yield.

The payment calendar

An average of $1,069 a month is a figure on paper. Real money arrives unevenly:

In a month with no coupon, no fund distribution and no tenant, only $125 comes in. If your bills are monthly while a big part of the income arrives twice a year, you need a buffer to draw on between payments.

Liquidity

The capital in the example has very different liquidity. The deposit and the bonds can be turned into cash fairly quickly, though often by giving up interest or by selling at a market price that may be below what you paid. The flat cannot be sold in a week. That least flexible 62.5% of the capital produces two thirds of the income.

How Not to Count the Same Income Twice

Most mistakes in passive-income plans are double counting.

• Yield versus total return. A fund that gained 8% over a year may have paid out only 2% of it. If the plan lists 2% of payouts plus 8% of growth, the 2% is counted twice. The payout is part of the total return, not something on top of it.
• Reinvested interest. When a deposit adds interest to the balance, that money never reaches your current account. It cannot be both spending money and capital growth.
• Price growth as income. A rise in the value of a flat or shares is not a payout. To spend it, you have to sell the asset or part of it, and that is the third flow, selling assets.
• Gross amounts in the budget. If the budget shows $2,000 of interest but $500 of it goes in tax, the budget contains $500 that does not exist.
• The emergency fund as an income source. If one deposit is both your rainy-day reserve and an income source, the income disappears exactly when you need the reserve.

What Happens When a Payout Falls or Stops

Payouts are not guaranteed, even after years of regular payments. Here is the same example in a bad but entirely possible year:

Income falls by 27.7%, from about $1,069 to about $773 a month. None of these events is a disaster on its own, but together they take more than a quarter of the budget.

A few more risks can break the plan:

• Inflation. Fixed income buys less every year. At an assumed 3% a year, after ten years $1,069 a month will buy only what about $795 buys today. Read more in the article on inflation.
• Default or bankruptcy. A company can go bust, a bond issuer can fail to pay, a bank can fail. Deposit guarantee schemes usually cover deposits up to a limit per depositor per bank, and they do not cover securities.
• Concentration. In the example two thirds of the income comes from one flat and one tenant. The bigger the share of a single source, the harder one event hits the budget. Diversification of income matters as much as diversification of capital.
• Currency. If the payouts are in one currency and part of your spending is in another, exchange-rate moves change what the income is worth.

The practical lesson: plan your spending around a bad year, not an average one, and decide in advance what you will do if income drops by a quarter: cut spending, use the buffer or sell some assets.

Yield Traps

Tables of "capital needed for X a month" push people towards the highest rate. A high yield is rarely free.

• Dividend yield after a price crash. Yield is calculated from past payouts. If a share price has collapsed because the company is in trouble, last year's dividend divided by the new price looks high, and the next dividend may be cut.
• Payouts out of capital. A product that pays out more than it earns is handing your own money back to you. The payout looks generous while the capital, and future payouts, shrink.
• A promise of a guaranteed high rate. If someone promises a return far above what government bonds in the same currency pay, ask who carries the risk and where the difference comes from. High guaranteed income with no risk is a classic sign of a fraudulent scheme.

Why higher income almost always means higher risk is explained in the article on risk and return.

If You Are a Ukrainian Tax Resident

For individuals who are Ukrainian tax residents, the Tax Code (version of 17 September 2026) sets these rates as of 20 October 2026:

The bank withholds the tax on deposit interest. Rent is taxed on the rent under the lease, not on what is left after repairs, and when the tenant is a private individual the landlord pays the tax quarterly and files an annual return. Income from foreign sources, such as distributions from a foreign fund held with a foreign broker, is also declared by the investor. The 5% military levy applies during martial law and until the end of the third calendar year after the year it ends.

For a sense of scale as of October 2026: the UIRD index of 12-month hryvnia deposits stood at 13.94% a year on 19 October 2026, and one-year OVDP sold at a weighted average yield of 15.01% at the 20 October 2026 auction. After 23% tax, a 13.94% deposit yields 10.73%, while annual inflation in Ukraine was 10.0% in September 2026. As of 20 October 2026, the Deposit Guarantee Fund repays deposits in full during martial law and for three months after it ends, after which the limit returns to 600,000 hryvnias per depositor per bank. OVDP are not deposits and are not covered by the Fund: the risk there is the state's ability to pay.

How to Check Your Own Passive-Income Plan

Start with a list of your sources and write down four numbers for each: gross payout per year, tax, costs and payment calendar. Then:

1. Work out net income for the year and divide it by 12 to get the average monthly figure.
2. Find the weakest month in the payment calendar and check that your buffer covers it.
3. Rerun the plan for a bad year, as in the table above.
4. Compare the net yield with inflation.

The passive income calculator adds up your sources into net income per month and per year, with a separate tax rate for each one. Subtract upkeep costs yourself: for a rental, enter the net rental yield, not the gross one. The calculator does not reinvest income; how a sum grows when payouts are reinvested first is covered in the article on compound interest.

To see this income in the context of your whole plan, Krokfolio lets you set how each asset pays out: a percentage a year or a fixed amount per month, such as rent. Its "Live on income only" approach checks whether dividends, interest, rent and pensions could cover your spending without selling investments. The other two approaches, spending down over your lifetime and following a withdrawal-rate rule, answer a different question: when your capital is enough if you gradually sell some of it.

Quick Answers to Common Questions

Is a rise in the value of my flat monthly income?

No. A higher property value increases your capital but brings in no cash until you sell. The monthly income from a flat is the rent minus tax and the owner's costs.

How do I account for the cost of keeping an asset?

Subtract it from the gross payout before you calculate the yield. For a rental, allow for empty months, repairs, insurance and utilities while the flat is empty. For funds and bonds, allow for broker and bank fees.

What happens to my plan if payouts are cut?

Income falls while spending stays the same. That is why it is worth testing the plan against a bad year: lower rates on renewal, reduced dividends, a longer empty spell for the flat. If income does not cover spending in that scenario, you need a buffer, lower spending or more sources of income.

Summary

Passive income is not the rate in a contract. It is what remains after taxes, fees and upkeep, spread across the months when the money actually arrives. In the worked example, rates of 4–6% turned into about 3.2% net on the whole capital, and a bad year took away more than another quarter of the income. Count net payouts, keep a buffer for uneven months, never count the same income twice, and plan your spending around a bad year rather than an average one.
