B. Planning and managing a person's money to meet needs and wants

Personal finance is the planning and management of an individual's money to meet their needs and wants. It involves smart decisions about how much to spend, how much to save, where to invest and how to prepare for future needs, such as buying a house in five years. Hiding all money away (c) is not management, and taxes or company accounts are not personal finance.

In the same budget, the family earns ₹40,000 a month and saves ₹8,000. What percentage of its income does the family save?

A bar chart of a family's monthly budget in six categories
  1. 20%
  2. 25%
  3. 80%
  4. 8%
Show the answer

A. 20%

Savings rate =8,00040,000×100=20%= \dfrac{8{,}000}{40{,}000} \times 100 = 20\%. 25% comes from dividing by spending (₹32,000) instead of income, 80% is the share that is spent, and 8% just copies the ₹8,000 figure. The chapter's activity asks the same question: what percentage of the money did you save?

In the chapter's activity, a family saves ₹30,000 at 8% compound interest a year. Using A=P(1+r)nA = P(1 + r)^n, find about how much interest it earns in 5 years. (Take (1.08)5≈1.4693(1.08)^5 \approx 1.4693.)

A chalkboard with the compound interest formula and the family's savings figures
  1. ₹12,000
  2. ₹14,080
  3. ₹44,080
  4. ₹2,400
Show the answer

B. ₹14,080

A=30,000×(1.08)5≈30,000×1.4693≈₹44,080A = 30{,}000 \times (1.08)^5 \approx 30{,}000 \times 1.4693 \approx ₹44{,}080, so interest =₹44,080−₹30,000=₹14,080= ₹44{,}080 - ₹30{,}000 = ₹14{,}080. ₹12,000 is simple interest (30,000×8×5100\dfrac{30{,}000 \times 8 \times 5}{100}), which ignores interest on interest; ₹44,080 is the amount, not the interest; ₹2,400 is only one year's interest.
