What is an Interest-Only Mortgage?
An Interest-Only Mortgage is a type of home loan where, for a specified period, the borrower pays only the interest on the loan. During this period, the principal loan amount remains unchanged because no principal is repaid.
Once the interest-only period ends, the borrower begins repaying both principal and interest, which usually results in higher monthly payments.
This type of mortgage is often chosen by borrowers who expect higher future income, short-term property ownership, or flexible cash-flow management.

Interest-Only Mortgage Calculation Formula
Step 1: Monthly Interest Payment
The monthly payment during the interest-only period is calculated as:
Monthly Interest Payment = (Loan Amount × Annual Interest Rate) ÷ 12
Or, using the annual rate as a decimal:
Monthly Interest Payment = Principal × (Annual Interest Rate ÷ 100) ÷ 12
Where:
- Principal (P) = Loan Amount
- Annual Interest Rate (R) = Interest Rate (%)
- Monthly Interest Rate = R ÷ 12
Since only interest is paid, the principal remains unchanged throughout the interest-only period.
Step 2: Total Interest Paid
Total Interest = Monthly Interest Payment × Number of Interest-Only Months
Step 3: EMI After Interest-Only Period
After the interest-only term ends, the remaining principal is repaid using the standard mortgage EMI formula:
EMI = P × r × (1 + r)n ÷ ((1 + r)n − 1)
Where:
- P = Remaining Principal
- r = Monthly Interest Rate
- n = Remaining Monthly Installments
Example Calculation
Suppose:
- Loan Amount = ₹60,00,000
- Annual Interest Rate = 8%
- Interest-Only Period = 5 Years
- Total Mortgage Term = 20 Years
Step 1: Monthly Interest Payment
Monthly Interest
= ₹60,00,000 × 8% ÷ 12
= ₹40,000
Step 2: Total Interest During 5 Years
₹40,000 × 60 Months
= ₹24,00,000
Step 3: Remaining Principal
Since only interest is paid:
Remaining Principal = ₹60,00,000
Step 4: EMI After Interest-Only Period
The remaining principal is then repaid over the remaining 15 years, resulting in a higher monthly EMI compared with the initial interest-only payment.
Note: These values are estimates. Actual payments may vary depending on the lender, interest-rate changes (for variable-rate loans), fees, taxes, insurance, and loan-specific conditions.

इंटरेस्ट ओनली मॉर्गेज कैलकुलेटर – केवल ब्याज भुगतान की गणना करें
मुफ्त ऑनलाइन Interest Only Mortgage Calculator
यदि आप ऐसा होम लोन लेने की योजना बना रहे हैं जिसमें शुरुआती वर्षों में केवल ब्याज (Interest) का भुगतान करना होता है, तो यह कैलकुलेटर आपके लिए उपयोगी है।
यह टूल आपकी मासिक ब्याज राशि, कुल ब्याज, शेष मूलधन (Principal) तथा इंटरेस्ट-ओनली अवधि समाप्त होने के बाद की अनुमानित EMI की गणना करता है।
Interest Only Mortgage क्या है?
Interest Only Mortgage ऐसा गृह ऋण है जिसमें निश्चित अवधि तक केवल ब्याज का भुगतान किया जाता है। इस दौरान मूल ऋण राशि (Principal) कम नहीं होती।
बाद में शेष अवधि में मूलधन और ब्याज दोनों का भुगतान किया जाता है, इसलिए EMI सामान्यतः बढ़ जाती है।
Interest Only Mortgage Calculator का उपयोग कैसे करें?
- ऋण राशि दर्ज करें।
- वार्षिक ब्याज दर दर्ज करें।
- Interest-Only अवधि दर्ज करें।
- कुल ऋण अवधि दर्ज करें।
- Calculate पर क्लिक करें।
इसके बाद आपको प्राप्त होगा:
- मासिक ब्याज भुगतान
- कुल ब्याज
- शेष मूलधन
- बाद की अनुमानित EMI
गणना का सूत्र
मासिक ब्याज भुगतान
मासिक ब्याज = (ऋण राशि × वार्षिक ब्याज दर) ÷ 12
कुल ब्याज
कुल ब्याज = मासिक ब्याज × कुल Interest-Only महीने
Interest-Only अवधि के बाद EMI
EMI = P × r × (1 + r)n ÷ ((1 + r)n − 1)
उदाहरण
यदि:
- ऋण राशि = ₹60,00,000
- ब्याज दर = 8%
- Interest-Only अवधि = 5 वर्ष
तो:
- मासिक ब्याज = ₹40,000
- 5 वर्षों का कुल ब्याज = ₹24,00,000
- मूलधन = ₹60,00,000 (जैसा का तैसा रहेगा)
इसके बाद शेष 15 वर्षों में मूलधन और ब्याज दोनों की EMI देनी होगी।
