Finance Calculator | Calculate Loans, Investments & Savings

Managing your finances requires understanding loans, investments, and savings. A Finance Calculator simplifies these calculations, helping you plan better, avoid mistakes, and make informed decisions. Whether you are borrowing, investing, or saving, this tool provides accurate results with formulas and step-by-step solutions.

Why a Finance Calculator is Important

• Planning: Helps forecast loan repayments, interest, and investment growth.
• Accuracy: Avoid manual calculation errors.
• Comparison: Compare different loan or investment options quickly.
• Learning: Understand how interest, time, and principal affect finances.

Key Financial Formulas

Here are the most important formulas used in finance calculations:

• Simple Interest (SI): SI = P × R × T / 100
• Compound Interest (CI): A = P × (1 + R/100)^T, CI = A − P
• Loan EMI (Equated Monthly Installment): EMI = [P × R × (1 + R)^N] / [(1 + R)^N − 1]
• Future Value of Savings: FV = P × (1 + r)^t
• Present Value: PV = FV / (1 + r)^t

How the Finance Calculator Works

1. Select the type of calculation: Loan, Investment, or Savings.
2. Enter known values such as principal, interest rate, duration, and frequency.
3. The calculator applies the relevant formula automatically.
4. Results are displayed instantly including totals, interest earned, or EMI amounts.

Step-by-Step Example 1: Simple Interest

Problem: Calculate simple interest for $5,000 at 6% per year for 3 years.
Formula: SI = P × R × T / 100
Solution: SI = 5000 × 6 × 3 / 100 = $900

Step-by-Step Example 2: Compound Interest

Problem: Calculate compound interest for $5,000 at 5% annually for 4 years.
Formula: A = P × (1 + R/100)^T, CI = A − P
Solution: A = 5000 × (1 + 0.05)⁴ = 5000 × 1.21550625 ≈ 6077.53
CI = 6077.53 − 5000 = $1,077.53

Step-by-Step Example 3: Loan EMI

Problem: Calculate monthly EMI for a loan of $10,000 at 12% annual interest for 2 years.
Formula: EMI = [P × R × (1 + R)^N] / [(1 + R)^N − 1]
Convert annual rate to monthly: R = 12% / 12 = 1% = 0.01, N = 2 × 12 = 24 months
Solution: EMI = [10000 × 0.01 × (1 + 0.01)²⁴] / [(1 + 0.01)²⁴ − 1] ≈ $470.73
