Solar loan EMI calculator

Enter the loan amount, your quoted rate and tenure. Use the rate from your own offer, not a guess, since solar loan rates vary a great deal between a scheme-linked bank loan and general finance.

Standard reducing-balance EMI, compounded monthly. Actual lender statements can differ slightly by rounding and processing fee treatment.

What rate should you enter

Scheme-linked loans under PM Surya Ghar, offered by nationalised banks through the Jan Samarth portal, have published rates near the repo rate plus 0.5 percentage points for smaller loans, historically around 5.75% a year for eligible amounts up to ₹2 lakh, with a higher published rate for the ₹2 lakh to ₹6 lakh slab. A general personal loan, NBFC solar loan or vendor-arranged finance can carry a meaningfully higher rate. Use the exact figure from your own sanction letter or offer, not this reference range, since rates are revised periodically and vary by lender and applicant profile.

How the EMI is calculated

This tool uses the standard reducing-balance formula banks use for a fixed-rate loan. Each month, interest is charged on the balance still owed, and the remaining EMI amount reduces the principal. Because the balance falls every month, the interest portion of each EMI falls too while the principal portion rises, even though the EMI itself stays the same.

Before you sign Confirm whether the rate is fixed or floating, ask for total repayment in writing, and check processing fees, prepayment charges and whether the PM Surya Ghar subsidy is adjusted against the loan or paid to you directly.
