In less than 6 years!
I witnessed an interesting experiment the other day using an compounding calculator. The presenter started with $20,000 and compounded it monthly, starting with 2%, and showed that it would take 16 1/2 years (199 months) to turn that 20,000 into 1 million. At 3% it took just over 11 years (134 months), 4% 8 1/2 years (101 months), and at 5% it took just 7 years. Nothing new here.
However the presenter then added an extra element or dimension to the calculation, and that was - additional periodical deposits. Here is how it went; starting with $20,000 and compounding monthly at 2%, and adding $500 a month from another source, the 20,000 turned into 1 million in only 13 1/2 years, 3 years less than the example above without the periodical additional deposits. Depositing $1000 a month, compounding at 2% a month, the 20,000 turned into 1 million in only 11 1/2 years. In fact, if you take $20,000, compound it at 5% per month and deposit $1000 a month on top, you’ll turn that 20,000 into 1 million in 5 3/4 years, or just 69 months.
