Investment growth calculator
Compound Interest Calculator
Estimate how your savings or investments may grow over time using compound interest and monthly contributions.
How compound interest works
Compound interest means your money can grow from both your original contributions and the growth earned over time. The longer money stays invested, the more powerful compounding may become.
Why monthly contributions matter
Regular monthly contributions can help increase long-term results. Even small contributions may grow significantly over many years when combined with compound growth.
Time and compound growth
Time is one of the most important factors in compound growth. A longer time period gives growth more opportunity to build on previous growth.
Choosing an annual return
The annual return is only an assumption. Actual investment returns can be higher or lower and may vary significantly from year to year.
