Compound Interest with Contributions Calculator
Project growth when you add a regular contribution on top of a starting amount.
Formula
Final value is the growth of the starting amount plus the future value of monthly contributions at the monthly rate.
How it works
Regular contributions often matter more than the starting amount over long periods. This assumes deposits at the end of each month and a steady rate.
FAQs
How do contributions change the result?
They add principal every month, and each deposit then compounds too.
What if I increase contributions later?
Run the calculator again with the higher amount for the remaining years.
Are taxes included?
No, this is a before-tax projection.
Are these figures financial advice?
No — they are estimates for planning only, not financial advice. Check with a qualified adviser for decisions involving large sums.
