Mortgage Calculator: How to Calculate Your Monthly Payment
A mortgage is a long-term loan provided by a bank, secured by the property you are purchasing, repaid in regular monthly installments that cover both principal and interest. It is one of the most significant financial decisions you will make.
How the Monthly Payment Is Calculated
Monthly installments are computed using the declining-balance (amortization) formula:
Monthly payment = [P ร r ร (1+r)^n] รท [(1+r)^n โ 1]
Where: - **P** = Principal (loan amount) - **r** = Monthly interest rate (annual rate รท 12) - **n** = Number of months (loan years ร 12)
Declining Balance vs. Flat Interest Rate
Most Egyptian banks apply the declining balance method on home loans, which is fairer to the borrower than flat-rate interest.
**Declining balance:** Interest is recalculated each month on the remaining principal. As you repay, both the outstanding debt and the interest component shrink over time.
**Flat rate (on original principal):** Interest is calculated on the original loan amount for the entire term regardless of repayments. It appears lower but is actually more expensive.
Practical Example with Numbers
**Loan of EGP 500,000 at 18% annual interest over 10 years:** - Monthly rate: 18% รท 12 = 1.5% - Number of months: 120 - **Approximate monthly payment: EGP 9,004** - Total interest paid: approximately EGP 580,480

- Annual percentage rate (APR)
- Loan-to-value ratio (LTV): typically 70โ80%
- Maximum loan term (can reach 20โ30 years)
- Processing fees, insurance, and registration charges
Hidden Costs to Watch Out For
- **Processing and file fees:** 0.5โ1% of the loan amount
- **Life insurance:** Mandatory at most banks, adds ongoing cost
- **Property insurance:** Protects the bank against disasters
- **Notary and property registration fees:** Additional legal costs
