What is the loan-to-deposit ratio formula?

Loans divided by deposits, multiplied by 100%. State whether loans are gross or net and match the entity scope and reporting date.

Is an LDR of 80–90% always healthy?

No. There is no universal safety range across bank business models and jurisdictions. Deposit stability, other assets, capital and funding access all matter.

What is the deposit-to-loan ratio formula?

Deposits divided by loans, multiplied by 100%. With loans of 80 and deposits of 100, LDR is 80% and the inverse is 125%.

Does an LDR above 100% mean the bank is insolvent?

No. It means loans exceed deposits under the selected definitions. Other liabilities and equity also fund the balance sheet; assess their terms and liquidity risks separately.

Does a low LDR guarantee deposits are held as cash?

No. The bank may hold securities or other assets. The ratio does not show cash reserves, asset liquidity or the insurance coverage of a depositor’s account.

Loan to Deposit Ratio: LDR Formula, Liquidity Risk, and Bank Health

The loan-to-deposit ratio (LDR) compares a bank’s reported loans with its deposits: loans / deposits × 100%. It describes lending relative to one funding source. It does not identify how each loan was funded or how much cash is available for withdrawals, and there is no universal 80–90% safe range.

See the decision guide

What LDR can and cannot tell you

Deposits are one source of bank funding alongside equity and other liabilities. Assets include loans, securities and cash. Comparing only loans with deposits leaves those other positions out, so the ratio is not a measure of cash reserves or solvency.

Observation	Possible explanation	Required follow-up
LDR rises	Loan growth, deposit outflows or changes in reporting scope	Inspect both balances and the funding used to replace lost deposits.
LDR falls	Deposit inflows, loan repayments, sales or write-offs	Check whether other assets or credit losses changed; lower is not automatically better.
LDR exceeds 100%	Reported loans exceed the chosen deposit base	Review other liabilities, equity, liquidity resources and refinancing needs.
Similar LDR across two banks	Similar loan size relative to deposits	Compare deposit concentration, insurance status, asset maturity, collateral and funding access.

Calculate comparable loan and deposit balances

Choose the definition used in the relevant bank disclosure or benchmark and keep it consistent. Gross loans, net loans after credit allowances, loans held for sale and leases can be treated differently. Domestic deposits and consolidated deposits are also different populations.

Record the filing date, entity scope, currency and whether balances are period-end or averages. Use compatible inputs.
Hypothetical example: gross loans are 80 million and deposits 100 million. Gross LDR = 80%. If the credit allowance is 2 million and the chosen net-loan measure deducts it, net LDR = 78%; label the definition rather than treating the figures as conflicting.
Using gross loans in that example, deposits / loans = 100 / 80 = 1.25, or 125%. This reciprocal is not an extra 25% cash reserve.
With loans unchanged at 80 and deposits falling to 80, LDR rises to 100%. The ratio alone does not show whether the bank paid withdrawals from cash, sold assets or obtained other funding.
Zero deposits make LDR undefined; zero loans make the inverse undefined. Missing fields should remain unavailable rather than silently becoming zero.

Compare LDR with liquidity and capital measures

Use each ratio for the question it actually measures. Neither a single threshold nor a high ranking proves a bank can meet an unexpected run.

Measure	Main question	Limitation
LDR	How large is the loan book relative to deposits?	Omits other assets, funding sources and withdrawal timing.
LCR	How much eligible liquidity covers prescribed 30-day stressed net outflows?	A modelled scenario, not a guarantee; applicability and reporting basis matter.
NSFR	Does available stable funding cover required stable funding under the rule?	Not a direct forecast of future market access.
Capital ratios	How much eligible loss-absorbing capital supports exposures?	Capital is not the same as available cash.

Use a defined peer group instead of an ideal range

Compare banks with similar business models and reporting definitions over several periods. A lending-focused bank and a custody bank can have very different ratios without either being automatically mismanaged.

Review insured and uninsured deposits, depositor concentration, brokered funding and maturity or repricing terms. No single category captures every source of withdrawal risk.
Inspect securities, unrealised losses, encumbrance and available collateral. A low loan ratio can hide risk elsewhere on the balance sheet.
For US industry data, the Federal Reserve H.8 release specifies its banking population and balance-sheet categories. Match dates and seasonal-adjustment basis; an industry aggregate is not a typical individual bank.
Do not treat historical figures without a defined population and source as benchmarks. A regulatory host-state loan-to-deposit test serves a different purpose from assessing an individual bank’s liquidity safety.
