How the growth is worked out

The formula is the amount times one plus the monthly rate, raised to the power of 120. For $10,000 at 6 percent that means a monthly rate of 0.5 percent and 120 months of growth.

Questions about this calculator

What yearly return would double $10,000 in 10 years?

About 7.2 percent a year. That is the rate at which $10,000 reaches $20,000 by year 10.

Is a lump sum of $10,000 better than depositing it monthly over 10 years?

For growth, yes. $10,000 invested at the start reaches $18,194. The same money split into 120 equal monthly deposits reaches only $13,657 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 10 years long enough for $10,000 to double at 6 percent?

$10,000 reaches $20,000 after about 11.6 years. So 10 years falls short. A quick check is to divide 72 by the rate, which gives 12 years.

What if the return on $10,000 over 10 years were one point lower than 6 percent?

At 5 percent the balance after 10 years is $16,470 instead of $18,194. One point higher gives $20,097.
