❓ Frequently Asked Questions (FAQ)
PITI stands for Principal, Interest, Taxes, and Insurance. It represents the full cost of homeownership for most mortgages. The P&I components go directly to the lender, while the Taxes and Insurance components are often held in an escrow account managed by the lender to ensure these annual obligations are met. It's the most accurate representation of your actual monthly housing expense.
Extra payments go directly toward reducing the principal balance of your loan. Since future interest is calculated on the remaining principal, reducing the principal early dramatically reduces the total interest paid over the life of the loan and shortens your payoff date. This calculator shows you exactly how much time and money you can save.
The amortization schedule is a table detailing every payment you will make over the life of the loan. It shows how much of each payment goes toward interest and how much goes toward principal, and what your remaining balance will be. In the early years, most of your payment is interest; in the later years, most is principal.
The Total Payment includes the original loan amount (principal) plus the Total Interest Paid over the entire loan term. For long-term loans like 30-year mortgages, the total interest paid can often equal or even exceed the original principal, especially with higher interest rates. This highlights the true cost of borrowing money.
Yes, while optimized for mortgages (with optional PITI fields), the core Principal and Interest (P&I) calculation can be used for any fixed-rate installment loan, such as auto loans or personal loans. Simply input the Loan Amount, Interest Rate, and Loan Term in years (or convert to months for total duration).

The Power of the Amortization Formula
The standard fixed-rate mortgage payment is calculated using a complex yet elegant formula. This formula determines the monthly payment amount required to pay off the entire loan (principal and interest) by the end of the term. The core formula for the monthly payment ($M$) is...
$$ M = P \frac{r(1+r)^n}{(1+r)^n - 1} $$...where $P$ is the principal loan amount, $r$ is the monthly interest rate (annual rate divided by 12), and $n$ is the total number of payments (loan term in years multiplied by 12).
