What does the mortgage calculator calculate?
The mortgage calculator is an online tool that calculates monthly mortgage payments, total interest, initial deposit requirements, and the amortization schedule for mortgage repayment. The calculator uses the standard annuity payment formula, which is used by most banks in Bulgaria. This formula ensures equal monthly payments throughout the repayment period. The calculator is useful for individuals who want to buy property and need to understand the financial implications of a mortgage, for those who want to compare different mortgage offers, and for anyone who wants to plan their budget and understand how mortgage payments affect their finances. It helps you make informed decisions about property purchases and choose the best mortgage offer for your needs.
How to use the mortgage calculator?
Using the mortgage calculator is very simple. Follow these steps:
- Enter the property value: Enter the purchase price or value of the property in BGN.
- Enter the initial deposit: Enter the amount you plan to pay as an initial deposit (usually 20-30% of the property value).
- Select the interest rate: Choose the annual interest rate in percentage (this can vary depending on the bank and your creditworthiness).
- Set the repayment term: Enter the repayment period in years (usually from 10 to 30 years).
- Calculate: Click the "Calculate" button to get the results.
- Review the results: View the monthly payment, total interest, total amount to repay, and the amortization schedule.
After calculating your mortgage payment, you can get personalized offers from several banks through our partner CREDiPORT.
Example with specific numbers
Example: Property worth 200,000 BGN, 20% deposit (40,000 BGN), 4% annual interest, 20 years
- Property value: 200,000 BGN
- Initial deposit (20%): 40,000 BGN
- Mortgage amount: 160,000 BGN
- Annual interest rate: 4% (monthly interest: 4% ÷ 12 = 0.333%)
- Term: 20 years (240 months)
- Monthly payment: ~970 BGN (calculated using annuity formula)
- Total amount to repay: ~232,800 BGN (970 × 240 months)
- Total interest: ~72,800 BGN (232,800 - 160,000)
In the first month, out of the ~970 BGN payment, about 533 BGN goes to interest, and the remaining 437 BGN goes to principal. With each subsequent payment, the principal portion increases, and the interest portion decreases.
Sources and notes
The mortgage calculator uses the standard annuity payment formula, which is used by most banks in Bulgaria. The formula ensures equal monthly payments throughout the repayment period. Real interest rates can vary depending on the bank, your creditworthiness, the type of property, the size of the initial deposit, and market conditions. Banks usually require a minimum of 20% initial deposit, but a higher deposit may reduce the interest rate. The calculator does not include additional expenses such as notary fees, property appraisal fees, insurance (life, property), or commissions that banks may charge.
