How Financial Calculations Work

Loan Payment Formula

Monthly loan payments are calculated using the standard amortization formula:

M = P × [r(1+r)^n] / [(1+r)^n - 1]

Where M = monthly payment, P = principal, r = monthly interest rate, n = number of payments

Compound Interest Formula

Investment growth is calculated using compound interest with regular contributions:

FV = PV(1+r)^n + PMT[((1+r)^n - 1)/r]

Where FV = future value, PV = present value, PMT = payment, r = interest rate, n = periods

Frequently Asked Questions

How accurate are these financial calculations?

Our calculations use standard financial formulas and are accurate for planning purposes. However, actual results may vary due to market conditions, fees, and other factors.

What's the difference between simple and compound interest?

Simple interest is calculated only on the principal amount, while compound interest is calculated on both the principal and accumulated interest, leading to exponential growth over time.

How much should I save for retirement?

Financial experts typically recommend saving 10-15% of your income for retirement. The earlier you start, the less you need to save each month due to compound interest.
