Calculate your investment growth with regular contributions and compound interest
Combining regular contributions with compound interest is one of the most effective wealth-building strategies. When you consistently add money to your investments, each contribution starts earning compound interest immediately, creating exponential growth over time.
Regular contributions accelerate your investment growth in three key ways:
Scenario: You start with $1,000 and contribute $500/month at 7% annual return for 30 years.
Without regular contributions, that same $1,000 would only grow to $76,123. Regular contributions added $180,000 but generated $475,000 in interest—that's the power of compound interest with contributions!
Contributing at the beginning of each period gives you slightly more growth because your money starts earning interest immediately. While the difference per period is small, it compounds over decades. For long-term investments, contributing at the beginning can add thousands to your final balance.
