Sale price: 10000
terms: 120
interest rate: 10
extra monthly payment: 100

Place some boundary checks in the amortizationPeriod() function, so we don't have negative values in "remaining principal" and "interest". This amortization schedule should've ended at month: 54, not 55.

Classic off-by-1 error.
