How is interest calculated on the current balance?

Imagine you have a piggy bank that gives you candy every day based on how many candies are already inside. That’s like interest being calculated on your current balance.

When money is in a savings account, the bank sometimes gives you extra money, like free candy, just for keeping your money there. The amount of this extra money depends on how much money you have at that moment. That's why it's called "current balance", because they look at how much is there right now before giving you the extra.

Let’s say you have $100 in your piggy bank, and the bank says, “We’ll give you $1 for every $100 you keep.” So, every day, you get $1, because that’s how much they gave based on what was there at the moment.

If you add more money later, like $50, now your balance is $150, and the bank might give you a little more candy, maybe $1.50, because it's looking at the current amount in the piggy bank again.

So, interest on the current balance means the extra money given depends on how much money is there right now, just like your piggy bank gives you candy based on what’s inside at that moment.
