<prompt> Human: Anyone happen to know a calculator that behaves like this? Lets say I wanted to throw 3kmo at debt with a given interest rate, Im interested to see how many months it would take before that debt is paid. I recall seeing one like this before but cannot seem to find it. Thanks!  <response>: balance-3k1APR12new balanceRinse and repeat. The number of times you have to do this before getting to zero is the number of months it will take.
