Frequently Asked Questions (FAQ)
What is the difference between Annuity and Differentiated repayment schedules?
Annuity payments remain constant throughout the loan term, with interest decreasing and principal increasing each month. Differentiated payments start high and decrease over time, as you pay a fixed principal amount plus interest on the remaining debt balance.
How does making extra principal payments affect my overall loan term?
Making extra payments directly reduces your loan's outstanding principal balance. Because interest compiles on the outstanding debt, reducing the principal accelerates your amortization schedule, shortening the loan term and lowering total interest paid.
What is the difference between the nominal interest rate and the Annual Percentage Rate (APR)?
The nominal interest rate is the base rate applied to your loan balance. The APR is a comprehensive indicator that factors in the nominal rate plus compounding frequency, bank commissions, and insurance fees, showing the true annual cost.
Why does the total amount repaid exceed the original loan amount by so much over a 30-year term?
This is due to the compounding effect of interest over time. Over a 30-year term, interest continues to accrue on the outstanding balance every single month. Even at low interest rates, 30 years of accrual can double the total cost.
Are bank fees and mortgage insurance (PMI) included in the amortization calculations?
No. This calculator computes the mathematical base of interest and principal based on your inputs. If you have additional monthly bank fees or Private Mortgage Insurance (PMI), you should add them to the calculated monthly payment.
