Dear student,
Interest coverage ratio= Net profit before interest and tax
Interest on long term funds
Here, Profit after tax=1,20,000
Tax=40%
Profit before tax=1,20,000*100/60=2,00,000
Here tax is 40% therefore balance profit is only 60% of original profit (profit made before tax calculation)
So to find out total profit made it is enough to multiply profit before tax with reciprocal of percentage of original profit after deducting tax (100-40=60)
Profit before tax= 2,00,000
Add Interest on debentures=1,00,000*15%=15000
Add Interest on mortgage loan=1,00,000*12%=12000
Profit before interest and tax= 2,27,000
Total interest on long term debt=15000+12000=27000
Interest coverage ratio= 2,27,000 = 8.4 times
27,000
Interpretation- Standard ratio on interest coverage is 6 to 7 times.Here the ratio is above ideal ratio indicating that interest charges of the company can be covered even if profit before interest and tax of the company falls to one eighth of the present level.
