HI Everyone .

Please help me out. Can anyone just tell me how to calculate Interest U/s., 234B and C  in cases where the Income tax officer has made an addition. For Ex. : Total Taxable Income at the original filing time was 6,00,000/- and the case was selected for scrutiny and addition of Rs. 40,000/- was made. At the time of filing assessee paid Rs. 2000 as interest for 234-B and 700/- For Interest 234-C. So now after taking into consideration the addition made by ITO we have to pay interest till date in case of 234B . so how to calculate . does anybody have a calculator for that. Whether 234C will change or not. Please help me out how to calculate or else provide a calculotor. 

Thanks
