Flat Interest Rate Formula = (P xtxi) : jb


P = original loan principal

I = interest rate per year

T = credit term by year

Jb = credit term by month.

2. Effective Interest Rate

This type of interest rate is using the calculation of the remaining principal amount of the loan. So that the amount of interest that must be paid will decrease as the installment period goes on. So, the less principal the loan, the smaller the interest that needs to be paid.

Effective Interest Rate Formula = SP x 1 x (30/360)


SP = monthly loan principal balance

i = interest rate per year

30 = number of days in 1 month

360 = number of days in 1 year

3. Annuity Interest Rate

The last type of interest rate based on the calculation is the annuity interest rate which is a combination of the effective interest rate and the flat interest rate. So the interest is calculated from the remaining principal of the loan and then divided evenly based on the repayment period.

Annuity Interest Rate Formula 

= Principal Installment + Effective Interest Installment

= PP xi : (1-1 : (1+i) xn)


PP = loan principal

n = number of installments

i = interest rate per year.
