Car Loan Payment

 The Car Loan Payment formula computes your monthly payment amount, including principal and interest, on a fixed interest car loan that, like most standard loans, compounds interest monthly.  This equation can be used to compute payment amounts for car loans and other standard personal loans.

INSTRUCTIONS: Choose units and enter the following:

• (L) Loan Amount
• (i%) Percent Interest Rate
• (n) Number of Months
  • Common Duration: between 36 and 72 months

The Math / Science

This formula is commonly used for auto loans and other simple debt.  The word AMORTIZATION comes from the Middle English amortisen which means "to kill".  In essence, this is the amount needed on a regular basis "to kill" a debt.  The formula for amortized payment is:

`MP =  (P * (r/12)) / (1- (1+(r/12))^(-12*N))`

where:

• MP = Monthly Payment
• P = Principal Loan Amount
• r = Annual Interest Rate
• N = Number of Years
