Budgeting, Savings and Debt Management for Clients

Updated 11 October 2026 · Fact-checked

Budgeting, savings and debt management means tracking a client's income and spending, finding the surplus, directing it to savings and goals, and keeping loan repayments affordable. You solve questions by computing surplus, savings rate and EMI-to-income ratio, then comparing them with the benchmarks given in the question.

Understand Budgeting, Savings and Debt Management

A budget is a plan for how a client's income will be used over a period, usually a month or a year. It lists income, then expenses. The gap between them is the surplus (income minus expenses) or a deficit if expenses are higher.

Spending falls into two broad groups. Fixed expenses stay the same each period, such as rent, EMIs and insurance premiums. Variable expenses change, such as food, travel and entertainment. Variable expenses are where a client can cut most easily. You may also see them split into needs and wants. Needs are essential. Wants are optional.

Savings planning puts the surplus to work. A good order is: first build an emergency fund, then make sure insurance cover is in place, then fund long-term goals such as retirement or education. Many advisers suggest paying yourself first: set aside savings as soon as income arrives, rather than saving what is left over. The savings ratio shows how much of income is saved.

Debt management means keeping borrowing under control. Debt is not bad in itself. Borrowing for a home can be sensible. The risk is too much debt compared with income. Advisers check the debt service ratio, which is total monthly loan repayments divided by gross monthly income. A commonly used guide is that total EMIs should stay within about 40% of income, and the EMI on a home loan alone within about 30 to 35%. These are guides, not legal limits. Use the figure the question gives.

When debt is too high, the adviser can suggest: clear high-cost debt such as credit card dues first, avoid new borrowing, prepay loans from surplus, or restructure loans to lower the EMI. Interest rate is the key. Pay off the costliest loan first, unless the question says otherwise.

Key formulas to remember

Surplus or deficit: Surplus = Total income − Total expenses (including EMIs); A negative result is a deficit. Use the same period (monthly or annual) for both.
Savings ratio: Savings ratio = Savings ÷ Gross income × 100; Check whether the question asks for gross or net income. Use what is stated.
Debt service ratio (EMI to income): Debt service ratio = Total monthly EMIs ÷ Gross monthly income × 100; A common guide is up to about 40%. It is a rule of thumb, not a law.
Housing EMI ratio: Housing EMI ratio = Home loan EMI ÷ Gross monthly income × 100; A common guide is about 30 to 35%. Compare only with the benchmark in the question.
Emergency fund: Emergency fund = Monthly essential expenses (including EMIs) × number of months; Three to six months is the usual guide. Use the months stated in the question.
Debt repayment priority: Repay the loan with the highest interest rate first; Credit card dues usually come first because the cost is very high.

How to solve Budgeting, Savings and Debt Management questions

Use this order for any numerical or judgement question on budgeting, savings and debt.

1Read what the question asks: surplus, a ratio, an emergency fund, or a recommendation.
2Put income and expenses on the same time basis. Convert annual to monthly, or the reverse.
3Separate fixed expenses, variable expenses and EMIs. Check that EMIs are not counted twice.
4Compute surplus, then the needed ratio using the formula above.
5Compare the result with the benchmark in the question. If none is given, use the common guide and say it is a guide.
6For a recommendation, follow the order: emergency fund, insurance, clear costly debt, then goal-based savings.
7Check the answer for sense: surplus less than income, ratio between 0 and 100, and units correct.

Quickest way: Ratio-first shortcut

When to use it: Use when the question gives income, EMIs and expenses and asks which option is correct, and time is short.

Write income and total EMIs, then divide to get the EMI-to-income ratio.
Compare with the benchmark in the question and reject options that contradict it.
If the question asks for priority, pick the highest-interest debt or the emergency fund before long-term investing.
Check the period (monthly or annual) before choosing the final option.

Common mistakes in Budgeting, Savings and Debt Management

Using net income in one place and gross income in another.
Both figures appear in the question and students pick the nearest number.
Fix: Use the income the formula needs. Debt service ratio normally uses gross income unless the question says otherwise.
Leaving EMIs out of expenses when computing surplus.
EMIs are listed under liabilities, so they feel separate from expenses.
Fix: Treat EMIs as a fixed outgo. Subtract them to get true surplus.
Mixing monthly and annual figures.
Income is given yearly and EMIs monthly.
Fix: Convert everything to one period before dividing.
Paying the smallest loan first without checking interest rates.
Clearing a small loan feels like a quick win.
Fix: Rank loans by interest rate and repay the costliest first, unless the question sets another rule.
Treating the 40% or 30% guides as fixed legal limits.
Benchmarks are quoted so often that they look like rules.
Fix: Call them guides. Use the figure in the question when one is given.
Recommending long-term investing before an emergency fund.
Students focus on returns and goals.
Fix: Build the emergency fund and adequate insurance first, then invest for goals.

Worked examples

Example 1

A client earns a gross monthly income of ₹1,00,000. Her EMIs total ₹35,000 and other monthly expenses are ₹40,000. Find her monthly surplus and EMI-to-income ratio.

Show the solution

Total outgo = EMIs + other expenses = ₹35,000 + ₹40,000 = ₹75,000.
Surplus = ₹1,00,000 − ₹75,000 = ₹25,000.
EMI-to-income ratio = ₹35,000 ÷ ₹1,00,000 × 100 = 35%.

Answer: Monthly surplus is ₹25,000 and the EMI-to-income ratio is 35%.

Example 2

A client has monthly essential expenses of ₹45,000, which include EMIs. The adviser wants an emergency fund of 6 months of these expenses. The client already holds ₹1,20,000 in a savings account kept for this purpose. How much more must be set aside?

Show the solution

Target fund = ₹45,000 × 6 = ₹2,70,000.
Shortfall = ₹2,70,000 − ₹1,20,000 = ₹1,50,000.

Answer: The client must set aside another ₹1,50,000.

Exam tips

Expect short numerical questions on surplus, savings ratio and EMI-to-income ratio. Practise them until they take under a minute.
Watch the wording: gross or net income, monthly or annual, and whether EMIs are inside the expense figure.
For priority questions, the usual answer is emergency fund first, then high-cost debt, then long-term goals.
Wrong answers carry negative marking of 25% of the question's marks, so skip a question only if you cannot narrow to two options.
Caselet questions reuse one data set. Compute surplus and ratios once and use them for every sub-question.

Practice questions from Evaluating the Financial Position of Clients

Budgeting, Savings and Debt Management: frequently asked questions

What is a good EMI to income ratio?

A common guide is that total EMIs should stay within about 40% of gross monthly income. It is a rule of thumb, not a legal limit. In the exam, use the benchmark given in the question.

Which debt should a client repay first?

Normally the one with the highest interest rate, such as credit card dues. This cuts the total interest paid. Follow any different rule that the question states.

How big should an emergency fund be?

The usual guide is three to six months of essential expenses, including EMIs. The right size depends on how stable the client's income is. Use the number of months stated in the question.

Is debt always bad in financial planning?

No. Borrowing can help buy a home or fund education. The problem is debt that is too high for the client's income or that carries a very high rate.
