How to Calculate Loan?

In the following sections you can get the step by step process to find loan. Go through the below segments and follow them.

  • Get the total loan amount, interest rate per month and number of months details.
  • Substitute all these values in the loan formula.
  • Solve the equation to get the monthly payment value.

Loan Payment Calculations

Before checking the loan formulas, have a look at the terminology used in the loan process.

  • Loan Amount: It is the original principal on a new loan or principal remaining on the old loan.
  • Monthly Payment: It is the amount to be paid towards the loan each month before the due date.
  • Number of months: The total number of payments needed to repay the loan.
  • Interest Rate: The annual nominal rate or stated rate of the loan.
  • Compounding: In general, interest will be compounded monthly as per the payments.

When you take the loan in the bank, you must pay the loan amount along with interest by making regular payments. So, for the loan calculations, we use the Present Value of an Ordinary Annuity formula.

Loan Amount PV = (PMT/i)[1 - 1/(1+i)n]

Other Loan Calculations:

Monthly Payment Amount PMT = (PVi(1+i)n]/(1+i)n-1)

Number of months n = [ln[(PMT/i)/((PMT/i)-PV)]/ln(1+i)

Interest rates can be calculated using the Newton-Raphson method.


PV is the loan amount

PMT is the monthly payment

i is the interest rate per month in decimal form

n is the number of months


Find the loan amount? If the interest rate is 5%, the monthly payment is $1500 and the number of months is 32.


Given that,

Number of months n = 32

Monthly payment PMT = $1500

Interest rate i = 5% = 0.05/12 = 0.004

Loan amount formula is PV = (PMT/i)[1 - (1/(1+i)n)]

PV = (1500/0.004)[1 - (1/(1+0.004)32]

= 44,850.32

Therefore, the loan amount is $44,850.32.
