Frequently Asked Questions
How much time does an extra monthly payment save on a 30-year mortgage?
On a $300,000 mortgage at 7% APR:
• Paying +$100/mo extra saves 3.5 years and ~$48,000.
• Paying +$250/mo extra saves 7.2 years and ~$92,000.
• Paying +$500/mo extra saves 11.5 years and ~$140,000 in interest.
Should I pay extra every month or save up for a yearly lump sum?
Paying extra every month is mathematically superior because interest compounds monthly on the unpaid principal. The sooner a dollar is applied to principal, the fewer days and months it has to generate compound interest.
Is there any risk in making extra monthly mortgage payments?
The only trade-off is liquidity. Once funds are paid into your mortgage principal, they cannot be withdrawn without a cash-out refinance or home equity line of credit (HELOC). Always maintain a 3-6 month emergency fund first.
Do extra monthly payments lower my next month's required payment?
No. On a standard fixed mortgage, your scheduled monthly payment remains identical, but the extra payment shortens your total loan duration (tenure reduction) so you finish your mortgage years early.
