Accounting Entry of installment.
Example with equation:
I = PRN/100

E is EMI

I is for Interest

P is Principal Loan Amount

r is rate of interest calculated on monthly basis. (i.e., r = Rate of Annual interest/12/100. If rate of interest is 9% per annum, then r = 9/12/100=0.0075) n is loan term / tenure / duration in number of months

Loan for 10 months

N = 1/12 for monthly intrest P = 2,50,000 R = 9%


I = 250000*9 / 100*12

I1 = 1875

Above screen is show calculation by month :

If rate is 9 %

Per month rate of interest is 0.0075

1st month principal amount is 2,50,000

Payment amount

EMI = P*r*(1+r)^n /((1+r)^n-1*(1 /100)

First Installment Calculation

250000*0.0075*(1 + 0.0075)^10 / ((1 + 0.0075)^10-1) = 26042.81

Installment amount = 4612.49 Interest amount = 1875.00 Principal amount = 3781.16

So next month Remaining Amount is 2,50,000 - 24167.81 = 225,832.19

Next month Interest amount = 225,832.19 * 9 * 1 / 12/ 100 = 1693.74

Second Installment Calculation

225,832.19*0.0075*(1 +0.0075)^9 / ((1 + 0.0075)^9 - 1) = 26042.81
