Interest-Only HELOC Calculator – Estimate Payments on Your Home Equity Line

Thinking of tapping into your home’s equity? Use our Interest-Only HELOC Calculator to see how much your monthly payments will be during the interest-only period of a Home Equity Line of Credit (HELOC).

Whether you’re funding a renovation, paying tuition, or consolidating debt, this tool helps you understand the real cost of borrowing against your home — with a clear breakdown of interest payments.

💡 What Is a HELOC?

A HELOC (Home Equity Line of Credit) is a flexible, revolving credit line secured by the equity in your home. Unlike a lump-sum loan, it works like a credit card — you borrow what you need, when you need it, up to a set limit.

HELOCs typically have two phases:

1. Draw Period (5–10 years) – Pay only interest on the amount you use
2. Repayment Period (10–20 years) – Pay back principal + interest

During the interest-only period, your payments are lower — but principal doesn’t reduce, which is why it’s crucial to calculate correctly.

🔧 How to Use the Interest-Only HELOC Calculator

This calculator helps you project monthly interest payments based on your usage and rate:

1. Enter Loan Amount Used (Not Total HELOC Limit)
   Example: $50,000 or ₹10,00,000
2. Enter Annual Interest Rate (%)
   Example: 8.5%
3. Choose Interest-Only Period (in months or years)
   Example: 10 years
4. Click “Calculate”
   Instantly see:
   • Your Monthly Interest-Only Payment
   • Total Interest Paid over the draw period

🧮 Formula Behind the Calculator

javaCopyEditMonthly Interest Payment = (Loan Balance × Interest Rate) ÷ 12

For example:
If you borrowed $40,000 at 8% annual interest:

Monthly Interest = (40,000 × 0.08) / 12 = $266.67

You’d pay this each month during the interest-only draw period.

🧠 Example Calculation

Borrowed Amount: ₹15,00,000
Interest Rate: 9%
Interest-Only Term: 5 years

Monthly Payment = ₹15,00,000 × 9% ÷ 12 = ₹11,250  
Total Interest Over 5 Years = ₹11,250 × 60 = ₹6,75,000

That’s ₹6.75 Lakhs in interest — without reducing your principal.
