💹 מה זו ריבית דריבית - ולמה כדאי להתחיל לחסוך מוקדם

Imagine you put 100 shekels into a savings account that pays 10% interest per year. After one year you'd have 110 shekels, that part is easy to understand. But what happens in year two? This is where a concept called 'compound interest' comes in, one of the most important ideas in anything related to money. In year two, the interest isn't calculated only on the original 100 shekels, it's calculated on the full 110 shekels you now have, including the interest you already earned. That means in year two you'd earn 11 shekels (10% of 110), not just 10 shekels like in year one. That sounds like a small difference, but over time this difference grows in a surprising way. If you keep this going for 20 years straight, the original 100 shekels would grow to more than 670 shekels, without adding even one extra shekel! The secret is that the interest 'works' on itself, not just on the original amount. That's why financial experts always say: the earlier you start saving, the more time compound interest has to 'work' for you. A kid who starts saving 50 shekels a month at age 10 will end up with far more money by age 30 than a kid who starts saving the same amount only at age 20, even if both save at exactly the same pace. Time, not just the amount, turns out to be the most powerful ingredient in building savings.
