Financial Planning in one look
budgeting what comes in against what goes out, and the arithmetic of income tax
Income, expenditure and savings
- income is everything coming in, from salary, interest, rent or a business
- expenditure is everything going out, and it splits into essential items such as food and rent and optional ones
- savings is simply income minus expenditure, and it is the single relation the whole first half rests on
- a budget is a plan written in advance, setting expected income against planned expenditure
- a surplus means income exceeded expenditure, and a deficit means the reverse
- investment is savings put to work so that it earns further income, rather than merely being held
The relations used in the sums
- the basic budget relation
S = I - E - savings as a percentage of income
S/I × 100 - expenditure when the savings rate is known
E = Ileft(1 - r/100right) - simple interest on a sum P
I = P × R × T/100 - amount returned after that interest
A = P + I
A budget question
Q. A person earns ₹45,000 a month and saves 20% of it. Find the monthly expenditure.
- savings are 20% of the income, not of anything else
- so the savings are 20/100 × 45000 = ₹9,000
- expenditure is income minus savings
- so E = 45000 - 9000 = ₹36,000
- the same answer comes directly from the remaining 80%: 80/100 × 45000 = 36000
- check that the two parts add back: 9000 + 36000 = 45,000, the whole income
Answer: the monthly expenditure is ₹36,000
