Questions about this calculator

What yearly return would double $100,000 in 5 years?

About 14.9 percent a year. That is the rate at which $100,000 reaches $200,000 by year 5.

Is a lump sum of $100,000 better than depositing it monthly over 5 years?

For growth, yes. $100,000 invested at the start reaches $134,885. The same money split into 60 equal monthly deposits reaches only $116,283 at 6 percent because most of it spends less time growing. Monthly deposits suit a budget while a lump sum suits cash you already have.

Is 5 years long enough for $100,000 to double at 6 percent?

$100,000 reaches $200,000 after about 11.6 years. So 5 years falls short. A quick check is to divide 72 by the rate, which gives 12 years.

What if the return on $100,000 over 5 years were one point lower than 6 percent?

At 5 percent the balance after 5 years is $128,336 instead of $134,885. One point higher gives $141,763.
