ETF/Stock DCA Simulator (DCA)

If the currency is KRW, use units of 10,000 KRW. For example, 300,000 KRW per month is 30, and 500,000 KRW is 50. If you switch to USD, enter the actual dollar amount you plan to invest each month.

Weekly mode treats the contribution input as a weekly amount and assumes 52 contributions per year. Monthly mode assumes 12 contributions per year. The start date is used for shareable state and period labels; the model does not use live market price data.

The annual return is a long-term growth assumption. For example, 7% means your assets are assumed to grow at 7% per year in a simplified model. The yearly contribution increase reflects salary growth or higher saving capacity, and controls how much your monthly contribution rises each year in % terms.

You specify the tax rate (%) and the annual fee rate (%). The model approximates how your gross annual return is reduced to a net return after these costs, and then applies that net rate at the monthly level. The default values are 15.4% tax and 0.5% annual fee, but real-world products may differ.

Markets fluctuate daily, and exchange rates, tax rules, and product structures can change over time. This calculator assumes a constant annual return and a simplified tax/fee model, so please treat it as a planning aid rather than a prediction engine.

If you set both the tax rate and fee rate to 0, the calculator removes those costs entirely. Gross and net performance become identical, which makes it easy to compare “with costs” vs “no costs” scenarios and see how much long-term drag taxes and fees can create.
