Investing to get rich: risk, decades, and a capital problem

Investing to get rich is not impossible: capital and the timeline matter

Compound interest has an awkward problem: it works, but it takes longer than average patience. Assuming 6-7% annual returns with a global index doubles your money in a decade; those who wait to live off that yield without having accumulated a good cushion beforehand fail. The real question is not whether the stock market goes up or down, but how much capital is needed for returns to be noticeable.

The 6-7% rule and its drawbacks

For the long-horizon investor, index funds tracking the MSCI World are the benchmark: a historical annual return of 6-7%. At that pace, money doubles in ten years without doing anything spectacular. The problem is that those starting at 45 do not have two decades ahead to see the full effect.

On the skeptical side are the examples cited time and again: the S&P 500 without gains between 2000 and 2014, or the Japanese stock market, viewed for years as a future bet and then frozen in a long horizontal. Fifteen flat years can derail anyone’s plan who needs liquidity at the wrong moment. In contrast, those who invested in the Ibex 35 five years ago have doubled their investment without complicating life, and that in the pure index, excluding dividends. The Spanish stock market, moreover, distributes dividends widely.

Initial capital is the boundary no one mentions

Calculations repeatedly show that returns without critical mass do not change lives. A 25% annual return on 5,000 euros is 1,500 euros before taxes: pleasant, but it does not free anyone from their paycheck. Hence the insistence that the barrier lies in the 100,000 euros saved. From there, the cash generated by the portfolio starts to be relevant.

The paradox is that gathering that figure with an average salary requires exactly what one wants to avoid: decades of discipline. Alternative paths are few and almost none depend on the market: inheritance, a high-salary job, selling property, lottery, or extreme savings. There is no shortcut consisting only of buying and waiting.

Real estate fares better than fixed income

In bricks, the estimates handled give the probability of success for rental property investment at 95%, with two-digit returns in some cases. The other 5%, involving occupancy and regulatory changes, weighs most in the analysis. The risk is not in the average, but in the specific case.

Fixed income does not fare as well. Some consider it a joke because in many brackets it does not even cover inflation. Banks frequently recommend it, but the recommended product usually coincides with the one charging the highest fees. For profiles over 60, it may make sense; for the rest, recent evidence suggests that a portfolio with much fixed income loses similarly in downturns and gains much less in upturns.

A real nine-year case and the compound interest point

Among circulating data, a practical case stands out: 95,000 euros contributed over nine years, a portfolio revalued by 187%, and annual dividends of about 7,000 euros after withholding tax. It is not a miracle; it is consistency, reinvestment, and time. Most analyses place the inflection point of compound interest around fifteen years. Until then, the curve seems flat and boring. Then it spikes, but almost no one endures it.

Gold: profitable but uncomfortable refuge

Gold also has its place in the list of obstacles. Those who bought ounces at 1,000 euros have seen their investment multiplied by four, up to 4,000. The problem arises when selling: bars are easy to counterfeit, coins require verification, and anyone displaying too many pieces raises questions. Profitable on paper, but with much less segarro liquidity than it seems.

There remains an awkward question, and it is not whether the stock market will rise next year. It is whether the system can support a majority of investors: if everyone achieved 20% annual returns, the result would be more inflation than prosperity. Between those who get rich and those who lose 40% lies a multitude that merely tries to prevent their quality of life from worsening. Perhaps that is the true pension plan.
