Useful checks
- Estimate annual and monthly dividend income.
- Apply a 0% input, the Korean general 15.4% withholding estimate, or a custom flat rate.
- Toggle reinvestment to see a simple user-entered projection.
Assumptions
- No live prices, ticker lookup, or market data are used.
- All amounts use the selected currency for formatting only; no exchange-rate conversion is performed.
- Projection uses annual end-of-year reinvestment at a constant share price and allows fractional shares.
- Projection assumptions are user-entered and not predictions; fees, inflation, exchange rates, and price changes are excluded.
- Amounts, shares, rates, and each named output use 4-decimal half-up rounding.
- The Korea preset estimates general resident domestic-dividend withholding: 14% national withholding plus local income tax equal to 10% of that withholding.
- It is not final annual tax. Aggregate financial-income taxation, the high-dividend election, residency and treaty rules, account exemptions, foreign-tax credits, security-specific rates, and payment-level rounding can change the result.
No investment advice
This is a user-input math estimate. It does not determine final tax, recommend securities, forecast returns, or fetch market data. Confirm current treatment with the National Tax Service or a qualified adviser.
