What is a Mortgage?

Mortgage is a long-term loan that individuals take from banks to purchase a home, build one, or renovate their existing home. Mortgage, one of the most commonly used loan types, is generally used with terms ranging from 5 to 20 years. Mortgage is also known as home loan, and the purchased property serves as collateral for the loan.

Mortgage calculation is critical for those who want to take out a loan because this calculation determines the monthly payment amount, total payment amount, and interest cost. A correct mortgage calculation provides a realistic picture when doing budget planning and helps make financial decisions more consciously.

Why is Mortgage Calculation Important?

Mortgage is one of the largest financial commitments in most people's lives. Therefore, mortgage calculation is an operation that must be done before taking out a loan. With correct calculation:

• Budget Planning: By knowing the monthly payment amount in advance, you can plan your budget accordingly.
• Loan Comparison: By comparing offers from different banks, you can determine the most suitable loan option.
• Interest Cost: By seeing the total interest cost, you can understand the real cost of the loan.
• Term Selection: By comparing different term options, you can choose the most suitable term for you.
• Preparation: Before applying for a loan, you can create a realistic payment plan.

How is Mortgage Calculated?

Mortgage calculation is done using an amortization table. Amortization is a table that shows how the loan's principal and interest payments are distributed over time. The basic formula used in mortgage calculation is as follows:

Monthly Payment = (Loan Amount × Interest Rate × (1 + Interest Rate)^Term) / ((1 + Interest Rate)^Term - 1)

This formula is used for fixed interest rate loans. Mortgages are generally given with fixed interest rate, but variable interest rate loans are also available in some cases.

Calculation Steps:

1. Determine Loan Amount: Determine the loan amount by subtracting the down payment amount from the value of the property you want to purchase.
2. Determine Interest Rate: Learn the interest rate offered by the bank. Interest rate is generally given on an annual basis.
3. Term Selection: Determine the period (in months) you want to repay the loan.
4. Calculate Monthly Payment: Calculate the monthly payment amount using the above formula or using online calculation tools.
5. Calculate Total Payment: Find the total payment amount by multiplying the monthly payment amount by the term.
6. Interest Cost: Calculate the total interest cost by subtracting the loan amount from the total payment amount.

Mortgage Calculation Examples

As an example, let's calculate for a $2,000,000 mortgage:

• Loan Amount: $2,000,000
• Interest Rate: 2.5% (monthly)
• Term: 120 months (10 years)
• Monthly Payment: Approximately $19,000
• Total Payment: $2,280,000
• Total Interest: $280,000

If 180 months (15 years) term is selected for the same loan amount:

• Monthly Payment: Approximately $13,500
• Total Payment: $2,430,000
• Total Interest: $430,000

As can be seen, as the term lengthens, monthly payment decreases but total interest cost increases. Therefore, term selection is very important and should be made according to your budget.

Types of Mortgages

Mortgages are generally classified as follows:

• Fixed Rate Mortgages: Interest rate remains fixed throughout the loan term. These loans provide a predictable payment plan.
• Variable Rate Mortgages: Interest rate can change according to market conditions. These loans may offer lower interest rates initially but are risky.
• Construction Loans: Loans used to build a home. Payment plans are usually made according to construction stages.
• Used Home Mortgages: Loans used to purchase used homes.
• New Home Mortgages: Loans used for newly built homes.

Requirements for Mortgage Application

For mortgage application, usually the following documents are required:

• Identity Document: ID card or passport
• Income Document: Pay stub, income certificate, or tax certificate
• Property Information: Deed information and appraisal report of the property to be purchased
• Down Payment Document: Document showing that the down payment amount has been paid
• Insurance: Home insurance and life insurance policies
