What Is a Mortgage?
A mortgage is a loan used to purchase property, typically repaid over a long period (15–30 years) with interest. The lender provides funds upfront, and you repay the loan in monthly installments.
Mortgage payments usually include:
- Principal (loan amount)
- Interest (cost of borrowing)
- Taxes and insurance (optional in some cases)
Financial institutions such as the Federal National Mortgage Association play a major role in supporting mortgage markets globally.
How the Mortgage Calculator Works
This calculator uses a standard mortgage formula to compute your monthly payments based on:
- Loan amount
- Interest rate
- Loan term (in years)
The formula calculates fixed monthly payments, ensuring your loan is fully repaid by the end of the term.
Mortgage Formula:
M=(1+r)n−1P×r×(1+r)n
Where:
- M = Monthly payment
- P = Loan amount
- r = Monthly interest rate
- n = Total number of payments
This ensures accurate and reliable results for financial planning.
