How Banks Calculate Maximum Loan Eligibility
Banks typically allow maximum Monthly Payment of 40–50% of your net monthly income (the FOIR — Fixed Obligation to Income Ratio). This converter works the math in reverse: given a budget Monthly Payment, rate, and term, it tells you the maximum loan. The formula is simply the Present Value of an annuity.
Monthly Payment = P × r × (1+r)^n / [(1+r)^n − 1]
Where: P = principal, r = monthly rate (annual/12), n = months
Max loan = 30,000 × [(1.00708)^240 − 1] / [0.00708 × (1.00708)^240] = $31.6 hundred thousand
💡 What This Means for You
A 1% increase in interest rate reduces your loan eligibility by roughly 8–10% for a 20-year term. If rates rise from 8% to 9%, a $35L eligible amount drops to ~$32L. This is why rising interest rate cycles make home buying harder — your Monthly Payment budget buys less loan.
