# When will I be a millionaire?

Barry monthly send 280 euros to the bank, which he deposits bear interest of 2.1% p. A. Calculate how many months must Barry save to save 1000000 euros?

Inflation, interest rate changes, or bank failures ignore.

Result

n =  1133 months

#### Solution:

$n = \lceil \dfrac { log( \dfrac{ 1000000 \cdot 2.1}{ 280 \cdot 100 \cdot 12} + 1)} { log(1+\dfrac{ 2.1}{100 \cdot 12})} \rceil = 1133 \ \text{ months }$
