Formulas Used

The money calculator uses various formulas depending on the type of calculation you perform. Here are some of the key formulas:

Compound Interest Formula

A = P(1 + r/n)^(nt)

Where:

A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per unit t
t = the time the money is invested or borrowed for, in years

Loan Payment Formula

M = P [i(1 + i)^n] / [(1 + i)^n - 1]

Where:

M = the monthly payment
P = the principal loan amount
i = the monthly interest rate (annual rate divided by 12)
n = the number of payments (loan term in years multiplied by 12)

Worked Examples

Example 1: Investment Calculation

Suppose you invest $10,000 at an annual interest rate of 5%, compounded annually. How much will your investment be worth after 10 years?

A = P(1 + r/n)^(nt)

A = $10,000(1 + 0.05/1)^(1*10)

A = $10,000(1.05)^10

A ≈ $16,288.94

After 10 years, your investment will be worth approximately $16,288.94.

Example 2: Loan Payment Calculation

You take out a $200,000 loan at an annual interest rate of 4.5% for 30 years. What will your monthly payment be?

M = P [i(1 + i)^n] / [(1 + i)^n - 1]

i = 4.5%/12 = 0.00375

n = 30*12 = 360

M = $200,000 [0.00375(1 + 0.00375)^360] / [(1 + 0.00375)^360 - 1]

M ≈ $1,073.64

Your monthly payment will be approximately $1,073.64.
