How the growth is worked out

With no deposits the math is short. Multiply $1,000 by one plus the monthly rate of 0.5 percent. Repeat that 360 times. The yearly return of 6 percent is spread across twelve months so each month earns a twelfth of it.

Questions about this calculator

Is 30 years long enough for $1,000 to double at 6 percent?

$1,000 reaches $2,000 after about 11.6 years. So 30 years is more than enough. A quick check is to divide 72 by the rate, which gives 12 years.

What if the return on $1,000 over 30 years were one point lower than 6 percent?

At 5 percent the balance after 30 years is $4,468 instead of $6,023. One point higher gives $8,116.

What is $6,023 worth after prices rise 2.5 percent a year?

If prices rise at 2.5 percent a year for 30 years the final balance has the buying power of about $2,871 in starting-year money. Enter your own inflation rate in the calculator to test other cases.

What if you added $100 a month to $1,000 over 30 years?
