Frequently Asked Questions
How do I calculate the effect of extra principal payments on loan payoff time?
Every extra dollar applied to principal permanently reduces the compounding balance. To calculate the exact time saved, the amortization formula recomputes the number of remaining periods: N = -ln(1 - (P x r) / Payment) / ln(1 + r), where 'Payment' includes your extra regular contribution.
How much extra payment is needed to cut my loan term in half?
On a typical 30-year mortgage at 6.5% to 7.5%, increasing your monthly payment by approximately 40% to 50% (e.g. paying $2,800 instead of $2,000) will cut your 30-year mortgage down to under 15 years.
Does paying bi-weekly also reduce payoff time?
Yes! By making half-payments every two weeks (26 half-payments = 13 full payments per year), you automatically make 1 extra full payment each year, cutting roughly 4 to 6 years off a 30-year mortgage without feeling a major monthly budget strain.
