Regular Investing Calculator
Grow wealth by investing a fixed amount each month.
About this calculator
Investing a fixed amount at regular intervals — pound-cost averaging — smooths your entry price and builds a habit. This calculator projects what steady monthly, quarterly, or yearly contributions could grow to, compounding at your expected annual return.
Enter your contribution, how often you invest, an expected return, and the number of years. The result splits your projected pot into what you put in versus the growth on top.
Frequently asked questions
What return should I assume?
Use a realistic long-run figure for your mix of assets. Global equities have historically returned high-single-digit percentages a year over long periods, but with significant volatility. The tool is only as accurate as the rate you enter.
Is pound-cost averaging better than a lump sum?
It reduces timing risk by spreading purchases, but historically investing a lump sum early has often produced more because money spends longer in the market. It depends on your circumstances and risk tolerance.
