Continue the comparison until the accumulated savings in the last column are
reduced to or below zero. That is the breakeven point in the comparison.
Once it is apparent that the savings will be exhausted in a given year, divide
the monthly costs into the previous year's total savings. This will tell you how
many months will occur during that period before the savings are exhausted.
For example, line 19 divided by line 22 equals 5.27 months.
