Total Sum^*:

Total Sum means the total of all licence fees or rent payable for full duration of licence period (maximium 60 months) including renewal period + amount of non - refundable depposit or advance or premium + interest calculated @ 10% per annum on refundable security deposit.

If premises is let out for a period of 2 years for Rs.20,000 per month and a non - refundable premium of say Rs.10,000 /- and a refundable deposit of Rs.1,00,000/- then

TOTAL SUM = (RS.20,000 * 24) + (Rs.1,00,000 * 0.10 * 2)
                         = (4,80,000) + (10,000) + (20,000)
                         = Rs.5,10,000

STAMP DUTY = Rs.5,10,000 * 0.25% = Rs.1,275/- Rounded of to Rs.1,300/-
