Separating dividend income from investment return
The income estimate multiplies investment value by a dividend yield. Yield is an assumption, not a contractual payment. Companies can reduce or cancel dividends, and a high quoted yield can reflect a falling share price rather than an unusually attractive opportunity.
Worked example
An investment value of £20,000 with an assumed 4% annual dividend yield gives £800 of gross annual dividends, or about £66.67 a month on average. That does not mean payments arrive monthly. Funds and companies use different distribution schedules.
Interpreting the result
The tax estimate depends on other income, the tax year and whether an ISA is selected. Do not confuse a cash distribution with a capital gain. An accumulating fund reinvests distributions; the absence of a cash payment does not by itself establish that no tax is due outside a tax shelter.
Checks before relying on the numbers
This tool is not a forecast of a specific company’s dividend. It excludes changes in capital value, so the income figure is not a total-return estimate. Confirm your holdings, account type and tax statements, and read the issuer’s distribution policy before relying on expected income.
