Loan-to-deposit ratio

Loan-to-deposit ratio is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Loan-to-deposit ratio rather than just read about it. In short: Loan-to-deposit ratio (LTD ratio or LDR) is a ratio between the banks total loans and total deposits. The ratio is generally expressed in percentage terms If the ratio is lower than one, the bank relied on its own deposits to make loans to its customers, without any outside borrowing.

Key takeaways

  • Loan-to-deposit ratio belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Loan-to-deposit ratio to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Loan-to-deposit ratio from memory before moving on to harder problems.

Reference excerpt

Loan-to-deposit ratio (LTD ratio or LDR) is a ratio between the banks total loans and total deposits. The ratio is generally expressed in percentage terms If the ratio is lower than one, the bank relied on its own deposits to make loans to its customers, without any outside borrowing. If on the other hand the ratio is greater than one, the bank borrowed money which it reloaned at higher rates, rather than relying entirely on its own deposits. Banks may not be earning an optimal return if the ratio is too low. If the ratio is too high, the banks might not have enough liquidity to cover any unforeseen funding requirements or economic crises. Banking analysts commonly used metric for assessing a bank's liquidity.

By country

Pakistan In Pakistan, loan-deposit ratio is known as the advance-to-deposit ratio (ADR) to describe the advances of loans to businesses and individuals out of total deposits. Since 2021, ADR tax is imposed on the banks in Pakistan if the ADR drops below 50. The Finance Act of 2021 imposed additional taxes on income from investments in federal government securities based on ADRs. The tax rates were set at 5%, 2.5%, and 0% for ADRs up to 40%, between 40 and 50%, and above 50%, respectively, in addition to a corporate tax rate of 39%. The Finance Act of 2022 revised these rates, introducing higher additional taxes of 20%, 14%, and 0% for the same ADR categories while maintaining the corporate tax rate at 35%. Starting in the tax year 2023, the additional tax rates were adjusted to 16%, 10%, and 0%, with the corporate tax rate increasing to 39%. In 2024, some banks in Pakistan, including Bank Alfalah, Bank of Punjab, and Habib Bank Limited, introduced a monthly fee on high desposits to reduce overall deposits and avoid ADR tax.

Worked examples

Example 1 — a first encounter with Loan-to-deposit ratio

Start with the simplest possible case. Write down what Loan-to-deposit ratio claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Loan-to-deposit ratio before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Loan-to-deposit ratio ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Loan-to-deposit ratio

In research
Loan-to-deposit ratio appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Loan-to-deposit ratio in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Loan-to-deposit ratio is common in secondary-school and first-year university syllabi. It links to neighbouring topics Finance stubs, Loans, so understanding it makes those chapters shorter.
In everyday life
Look for Loan-to-deposit ratio outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
