Sir, We have taken Bank Guarantee of Rs.2892000 for 10 years. As per bank circular BG commission charges 0.30% per month. Bank is charging the commission on full amount. But sum bank charge the commission per thousnd amount, i.e. 2892000/1000*0.30 per month amount is Rs. 867.60. It is the correct calculation or not. If it is correct, inform if any RBI Circular or guidline please.
