Common US Calculations

Here are some of the most frequently used US-specific calculations:

Sales Tax Calculation

The sales tax formula in the US is typically:

Sales Tax = (Price × Tax Rate) / 100

For example, if you purchase an item priced at $100 in a state with a 7% sales tax:

Sales Tax = ($100 × 7) / 100 = $7.00

Mortgage Payment Calculation

The standard mortgage payment formula is:

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

Where: M = monthly payment, P = principal loan amount, i = monthly interest rate, n = number of payments

For a $200,000 loan at 4% interest over 30 years:

Monthly payment ≈ $1,073.64
