Questions about this calculator

What if you stopped the $1,000 deposits halfway through 30 years at 6 percent?

After 15 years the balance is $290,819. Left alone for the second half, it would grow to $713,696 instead of $1,004,515.

What would it take to match $1,004,515 over 30 years if you started 5 years later at 6 percent?

You would need $1,449.53 a month for 25 years instead of $1,000 for 30. Starting early does much of the work.

How much would $2,000 a month reach over 30 years at 6 percent?

$2,009,030 at 6 percent. That is 2 times the balance from $1,000 a month.

What if the return on $1,000 a month over 30 years were 5 percent instead of 6?
