Formula Explained
Calculator ke peeche do main formulas kaam karte hai. Chaliye dono ko detail mein samajhte hai.
Simple Interest Formula
Simple interest ka formula bahut simple hai. Yeh sirf principal amount par calculate hota hai.
SI = (P x R x T) / 100
Jahan P = Principal amount, R = Annual interest rate (%), T = Time in years. Iske baad monthly interest nikalne ke liye total interest ko total months se divide karte hai. Monthly Interest = SI / (T x 12). Ya seedha (P x R) / (100 x 12) bhi use kar sakte ho agar sirf monthly interest chahiye.
Compound Interest Formula
Compound interest thoda complex hai kyunki isme interest par bhi interest milta hai.
A = P x (1 + R/n)^(n x T)
Jahan A = Maturity amount, P = Principal, R = Annual rate (decimal mein), n = Compounding frequency per year, T = Time in years. Total interest = A - P. Monthly interest ke liye total interest ko total months se divide karte hai.

Practical Examples
Example 1: Fixed Deposit Monthly Interest
Ramesh ne 5,00,000 rupees ka FD kiya 7% annual interest par 5 years ke liye. Compound interest with quarterly compounding. Using the formula, maturity amount will be approximately 7,07,389 rupees. Total interest earned is 2,07,389 rupees. Monthly interest comes to around 3,456 rupees. Yeh FD se monthly income banane ke liye perfect option hai.
Example 2: Personal Loan Interest Calculation
Sunita ne 3,00,000 rupees ka personal loan liya 12% interest par 3 years ke liye simple interest par. Total interest = (3,00,000 x 12 x 3) / 100 = 1,08,000 rupees. Monthly interest = 1,08,000 / 36 = 3,000 rupees. Plus principal bhi har mahine dena padega.
Example 3: Savings Account Interest
Aapke savings account mein average 2,00,000 rupees balance hai. Bank 3.5% interest de raha hai. Annual interest = (2,00,000 x 3.5) / 100 = 7,000 rupees. Monthly interest = 7,000 / 12 = approximately 583 rupees. Savings account mein interest daily calculate hota hai aur quarterly credit hota hai.
Example 4: Recurring Deposit Calculation
Amit har mahine 5,000 rupees RD mein daalta hai 5 years ke liye 6.5% interest par. Yahan calculation thoda complex hai kyunki har month naya deposit hota hai. Total invested = 5,000 x 60 = 3,00,000 rupees. Maturity approximately 3,56,800 rupees. Total interest lagbhag 56,800 rupees. Monthly interest average around 946 rupees.
Example 5: High Value FD Monthly Payout
Priya ne 10,00,000 rupees ka senior citizen FD kiya 8% interest par 1 year ke liye with monthly payout option. Annual interest = 80,000 rupees. Monthly interest = 80,000 / 12 = 6,667 rupees. Yeh regular monthly income ke liye best option hai jisme principal safe rehta hai.
Example 6: Gold Loan Interest
Vikas ne 4,00,000 rupees ka gold loan liya 12% interest par 1 year ke liye. Monthly interest = (4,00,000 x 12) / (100 x 12) = 4,000 rupees. End mein principal wapas karna hoga. Gold loans mein usually sirf interest monthly dena hota hai.
