Find loan balance formula below,

B = Balance Amount
A = Loan Amount
P = Payment Amount
r = Rate of Interest (compounded)
n = Number of time periods

Solved Examples


Find the balance loan after 1 year, when the original loan amount is Rs 100000, the monthly payment amount is Rs 900 and the annual interest rate of 4%.


Given Original loan amount A = 100000

B = Balance Amount

P = 900

r =4/1200 = 0.0033

n = 01 years = 12 months

Using the loan formula:

\(B=A(1+r)^n-\frac{p}{r}[(1+r)^n -1]\)

\(B=100000(1+0.0033)^{12}-\frac{900}{0.0033}[(1+0.0033)^{12} -1]\\ =100000\times 1.0403-272727.27(1.0404-1)\\ =104030-10990.9\\ =93039.1\)
