Frequently Asked Questions
How is mortgage interest calculated?
Most mortgages use an amortization formula where each monthly payment covers both interest and principal. Early payments are mostly interest, and the balance shifts toward principal over time. Our mortgage calculator shows this full breakdown.
What is the difference between APR and interest rate?
The interest rate is the cost of borrowing the principal amount. APR (Annual Percentage Rate) includes the interest rate plus other charges like origination fees, giving you a more complete picture of the total cost of a loan.
How much should I save for an emergency fund?
A common guideline is three to six months of essential expenses. Use our savings calculator to estimate how long it takes to reach your target based on your monthly contributions.
Can I compare different loan options side by side?
Yes. Run each scenario in the calculator separately and note the total interest paid and monthly payment. Comparing these numbers across different rates and terms makes it easy to see which option saves you the most.
