Calculate subsidized rooftop solar loan EMI and electricity bill savings under PM Surya Ghar Yojana. Designed specifically for Indian investors, salaried professionals, business founders, and taxpayers under the latest RBI and Income Tax guidelines for FY 2026-27.
📐 Mathematical Formula & Calculation Logic
The underlying actuarial compounding and financial formula executed in real-time by this tool:
EMI = [P × r × (1 + r)ⁿ] / [ (1 + r)ⁿ - 1 ]
P: Principal / Initial Capital or Periodic Investment
r / i: Periodic Rate of Return / Interest Rate
n / t: Number of Compounding Cycles / Tenure in Months/Years
M / A: Total Wealth Accumulation / Maturity Value
💡 Practical Example (Case Study)
If you take a home loan of ₹50,00,000 at 8.5% interest rate for a 20-year tenure, your monthly EMI will be ₹43,391. Total interest paid will be ₹54,13,879, making your total repayment ₹1,04,13,879.
