Mr Raman, age 32, works for a bank as a senior manager. He earns Rs 50,000 per month take-home salary. His wife works as a school teacher earning Rs 15,000 per month. Raman had, earlier in his career, sold life insurance policies as an agent earning roughly Rs 50,000 per annum (Rs 4200 per month) as renewal commission every year from those policies sold. Raman has a flat of his own plus a small investment property in neighbouring suburb giving him Rs 15,000 p.m. rent. Raman has a decent small savings portfolio giving him an interest of Rs 5,000 per month. Raman believes he will increase his savings income from Rs 5000 to 15,000 in 5 years time as he plans to save all of his annual bonus (Rs 1.5 lacs per annum) every year.
Residual income is the amount of net income generated in excess of the minimum rate of return. Residual income concepts have been used in a number of contexts, including as a measurement of internal corporate performance whereby a company's management team evaluates the return generated relative to the company's minimum required return. Alternatively, in personal finance, residual income is the level of income that an individual has after the deduction of all personal debts and expenses have been paid.
