Calculation Details

Loan Amount Calculation Formula:

The maximum loan amount you can afford is calculated using the formula:

Loan Amount = (Monthly Income - Monthly Expenses) / ((1 - (1 + (Interest Rate / 100) / 12)^(-Loan Term * 12)) / ((Interest Rate / 100) / 12))


This formula calculates the loan amount based on your monthly income, monthly expenses, interest rate, and loan term. It takes into account the monthly compounding of interest.

Calculation History

    Loan Affordability

    1. Loan Affordability: This concept refers to how much a person or household can borrow without risking financial strain. It’s based on income, existing debt, expenses, and the loan’s terms.
    2. Debt-to-Income Ratio (DTI): The debt-to-income ratio is a key factor in determining loan affordability. It’s a measure of personal finance used by lenders to gauge an individual’s ability to manage monthly payments and repay debts.

    Mathematics Behind Loan Affordability

    1. Debt-to-Income Ratio Calculation:
      • Formula: DTI = (Total Monthly Debt Payments / Gross Monthly Income) × 100
      • Components: Includes all debt payments, such as existing loans, mortgage payments, credit card payments, etc., divided by gross monthly income.
    2. Affordability Calculation:
      • Estimating Affordable Payment: Based on industry standards, lenders prefer a DTI ratio below 36%, with no more than 28% of that debt going towards servicing a mortgage or rent payment.
      • Back-End Calculation: This approach considers all debt obligations, not just the housing costs.
