Loan Eligibility Calculator - Borrowing Capacity & FOIR Planner
Calculate your maximum eligible loan amount based on your net monthly income, existing debt obligations, and the bank's FOIR (Fixed Obligations to Income Ratio) limit.
AI Quick Summary
Definition & Purpose:
This calculator estimates the maximum loan amount a bank is likely to approve, based on net monthly income, existing debt obligations, and the lender's maximum FOIR (Fixed Obligations to Income Ratio) — the share of income a borrower can safely allocate to debt repayment.
When to Use:
Use this calculator before applying for a home, personal, or auto loan to estimate how much a lender is likely to approve based on your income and existing debts.
Key Takeaway Insights:
- FOIR (Fixed Obligations to Income Ratio) caps the share of monthly income a lender will let you commit to debt repayment, typically 40% to 60% depending on the lender and income bracket — this calculator uses that cap, minus your existing EMIs, to find your remaining monthly loan budget.
- The maximum eligible loan amount isn't set directly by income alone — it comes from reversing the standard EMI formula, converting your maximum affordable monthly payment into the largest principal that payment could service over the chosen tenure and rate.
- Paying off existing debts before applying, or extending the loan tenure, both increase the maximum eligible amount — paying down debt frees up more of the FOIR budget, while a longer tenure lowers the EMI needed to service any given loan size.

Eligible Borrowing Capacity
Introduction
Loan Eligibility Calculator – Borrowing Capacity & FOIR Guide
Before approving a loan, lenders check whether your income can realistically support the repayment without over-extending your finances. This calculator estimates your maximum monthly EMI budget and the largest loan amount that budget could service, based on your income, existing obligations, and the lender's FOIR limit.
The Two-Step Eligibility Formula
Step 1 — Maximum EMI budget:
Max EMI = ≤ft(Net Monthly Income × (FOIR / 100)) - Existing Monthly EMIs
Step 2 — Maximum loan principal (the standard EMI formula, reversed to solve for principal):
Max Loan = Max EMI × ((1 + r)^N - 1 / r × (1 + r)^N)
Where r is the monthly interest rate and N is the tenure in months.
Worked Example
A 10,000 monthly income, 1,500 in existing EMIs, a 50% FOIR limit, 7.5% interest, over a 20-year term:
- Max EMI budget: (10,000 × 0.50) - 1,500 =3{,}500$ per month
- Monthly rate: 7.5 ÷ 12 ÷ 100 = 0.00625
- Total months: 20 × 12 = 240
- Max loan amount: 3,500 × dfrac(1.00625)^240 - 10.00625 × (1.00625)^240 ≈434{,}462.46$
How Tenure Changes Eligibility
The same $3,500 monthly EMI budget can support very different loan sizes depending on the tenure — a longer term lowers the payment required per dollar borrowed, which raises the maximum principal that budget can service:
| Tenure | Max Eligible Loan Amount |
|---|---|
| 10 years | $294,856.60 |
| 15 years | $377,556.99 |
| 20 years | $434,462.46 |
| 25 years | $473,618.64 |
| 30 years | $500,561.70 |
How the FOIR Limit Changes Eligibility
At the same 10,000 income,1,500 existing EMIs, 7.5% rate, and 20-year term, a lender's FOIR policy alone can swing eligibility significantly:
| FOIR Limit | Max EMI Budget | Max Eligible Loan Amount |
|---|---|---|
| 40% | $2,500 | $310,330.33 |
| 50% | $3,500 | $434,462.46 |
| 60% | $4,500 | $558,594.59 |

Worked Examples Calculation
110,000 Income,1,500 Existing EMIs, 50% FOIR, 7.5% Interest, 20-Year Term
Net Monthly Income = 10,000, Existing Monthly EMIs =1,500, FOIR Limit = 50%, Interest Rate = 7.5% p.a., Tenure = 20 Years
Max EMI = (10,000 50%) - 1,500 = 3,500/month. Monthly Rate (r) = 7.5/12/100 = 0.00625. Total Months (N) = 240. Max Loan = 3,500 [(1.00625)^240 - 1] / [0.00625 * (1.00625)^240] =434,462.46.
Max Monthly EMI Allowed = 3,500 | Max Eligible Loan Amount =434,462.46 | Existing Debt Ratio = 15% of income
2Same Profile, 30-Year Term Instead of 20
Net Monthly Income = 10,000, Existing Monthly EMIs =1,500, FOIR Limit = 50%, Interest Rate = 7.5% p.a., Tenure = 30 Years
Max EMI stays 3,500/month, but extending the tenure to 360 months lets that same monthly budget support a larger loan: Max Loan = 3,500 [(1.00625)^360 - 1] / [0.00625 (1.00625)^360] =500,561.70.
Max Monthly EMI Allowed = 3,500 | Max Eligible Loan Amount =500,561.70

Limitations & Common Mistakes
- Entering incompatible unit formats (e.g. Mixing Metric and Imperial).
- Typographical mistakes in numeric entry fields.
Uses a single FOIR percentage and a single fixed interest rate for the full tenure — actual bank approval also depends on credit score, employment verification, collateral, and each lender's individual underwriting policy, which can differ meaningfully from this estimate.
Frequently Asked Questions (FAQ)
Q:What is FOIR in loan eligibility calculations?
FOIR (Fixed Obligations to Income Ratio) is the percentage of your net monthly income that a lender will allow you to commit to fixed debt obligations — including the new loan's EMI plus any existing EMIs. Lenders commonly cap FOIR between 40% and 60%, with higher-income applicants sometimes qualifying for higher limits.
Q:How can I increase my loan eligibility?
Three common levers: paying off or reducing existing debts to free up more of your FOIR budget, adding a co-applicant so their income is pooled into the eligibility calculation, or extending the requested loan tenure, which lowers the monthly EMI needed to service the loan and lets the same income support a larger principal.
Q:Does a credit score affect loan eligibility?
Yes, though not directly through this calculator's formula. A strong credit score (typically 750 and above) makes lenders more willing to offer a higher FOIR limit and a lower interest rate, both of which increase the maximum loan amount you'd actually be able to borrow in practice.
Q:What happens if my existing EMIs exceed the FOIR limit?
If your existing monthly obligations already meet or exceed the maximum FOIR budget, your available EMI capacity drops to zero and the calculator shows no additional loan eligibility — you'd need to reduce existing debt, increase income, or find a lender with a higher FOIR limit before qualifying for more borrowing.
