📅 Biweekly Payment Simulation
Biweekly payments = 26 half-payments/yr = 13 full payments/yr (1 extra). Saves ~3–7 years on a 30yr mortgage.
Round Up Your Payment
If your payment is $1,847, round to $2,000. The extra $153/mo adds up to years off your mortgage.
Biweekly Payments
Pay half your monthly payment every 2 weeks. You'll make 26 half-payments = 13 full payments/year — one extra per year.
Apply Windfalls
Tax refunds, bonuses, and raises applied to principal early in the loan have the biggest impact on total interest.
Refinance Consideration
If rates drop 1%+, refinancing to a shorter term can dramatically cut total interest, especially in early years.
