How to use Investment Calculator
Enter the starting amount and monthly contribution.
Enter the expected return, years, compounding and optional inflation.
Read the final value and the yearly growth table.
Worked example
10,000 plus 500 a month at 7% for 20 years grows to about 300,000, of which 130,000 is your money and the rest is growth.
What return should I use?
Use a cautious long-run average for your mix of investments; past returns do not guarantee future ones.
Why add inflation?
It shows what the future amount is worth in today’s money.
