📚 Understanding Compound Interest

Compound Interest

Interest earned on both the initial investment and previously earned interest. The power of compounding grows over time.

Contribution Timing

Contributing at the beginning of each period allows your money to earn interest for the entire period, maximizing growth.

Tax Impact

Interest earnings may be subject to income tax, which can significantly reduce your effective returns over time.

Inflation Effect

Inflation reduces the purchasing power of money over time. Your investment needs to outpace inflation to maintain real value.
