Formula Explained

The financial calculator uses standard financial formulas to compute the results. The most common formulas used are:

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

Where:

PMT: Periodic payment
PV: Present value
FV: Future value
r: Interest rate per period
n: Number of periods

These formulas are based on the principles of compound interest and are widely used in finance to calculate loan payments, investment growth, and other financial transactions.

Worked Examples

Let's look at a few examples to understand how the calculator works.

Example 1: Calculating Monthly Loan Payment

Suppose you want to borrow $200,000 at an annual interest rate of 5% for 30 years. You can use the calculator to find the monthly payment.

Using the formula:

PMT = 200000 * (0.05/12 * (1 + 0.05/12)^360) / ((1 + 0.05/12)^360 - 1)

The calculator will compute the monthly payment as approximately $1,199.55.

Example 2: Calculating Future Value of an Investment

If you invest $10,000 at an annual interest rate of 7% for 10 years, you can use the calculator to find the future value.

Using the formula:

FV = 10000 * (1 + 0.07)^10

The calculator will compute the future value as approximately $20,589.11.

Frequently Asked Questions

What is the difference between PMT, PV, and FV?

PMT stands for periodic payment, which is the amount paid regularly, such as monthly mortgage payments. PV is the present value, which is the current worth of a future sum of money. FV is the future value, which is the value of an investment or loan at a specific point in the future.

How accurate are the results from this calculator?

The results from this calculator are based on standard financial formulas and are accurate as long as the input values are correct. However, real-world financial transactions may have additional factors that affect the outcome.

Can I use this calculator for both loans and investments?
