Usein kysytyt kysymykset
Does making extra payments hurt my credit?
No. Extra payments reduce principal faster and demonstrate financial responsibility. Your credit score may improve as debt-to-income ratio improves.
Can I make extra payments on any loan?
Most mortgages and auto loans allow extra payments without penalty, but check your loan agreement. Some car leases or older mortgages may have prepayment penalties.
Is $50/month extra payment really significant?
Yes. On a $200k mortgage at 6.5%, an extra $50/month saves ~$20k in interest over 30 years.
