In Spain, dividends and capital gains are taxed under the Personal Income Tax (IRPF) savings base. Rates increase as your portfolio grows, and if you don't plan well, you could be handing over a significant part of your long-term compound interest to the State.
Savings Tax for Investors
Dividends and capital gains are grouped in the savings base, with increasing brackets based on the annual amount.
What this calculator does
It calculates the future value of your portfolio with an initial contribution, monthly contributions, and a compound annual return. Later, we will add the tax layer.
Dividends and capital gains are taxed in the savings base. As your portfolio grows and your annual returns increase, you move through different brackets that increase the effective tax pressure on your investment.
Think of the savings base as a three-block ladder:
The specific details change by tax year and region, but the logic is clear: the more you generate in the savings base, the higher your marginal rate will be.
The same portfolio, with the same assets, can yield very different results depending on where you live, how you collect dividends, and when you realize capital gains.

Helps you fit your goals (FI, retirement, buying a home…) into the calendar.
This tool is for guidance only and does not account for taxation, real fees, or exchange rate changes. The next step is to incorporate the effect of taxes on dividends and capital gains to see the net future value.
The calculator numbers are gross. In practice, every dividend collected in cash, every rushed sale, and every structure change without a plan can destroy part of the compound interest through unnecessary taxes.
