Provides a reusable sanctioned limit for eligible short cash-flow gaps.
Business & revolving credit
An overdraft is a revolving facility that allows an eligible account holder to draw beyond the available balance up to a sanctioned limit under stated conditions. It is designed for short, fluctuating cash gaps—not permanent losses or long-lived assets.

Quick answer
Provides a reusable sanctioned limit for eligible short cash-flow gaps.
It may be secured or unsecured, with renewal and operating conditions.
Interest commonly depends on utilised amount and time, while other charges may use the full limit.
The key decision is whether cash reliably returns to reduce utilisation.
Direct answer
An overdraft loan or facility permits an eligible borrower to withdraw more than the available account balance up to a sanctioned limit. As receipts enter the account, utilisation can fall and available drawing power can return under the contract. It differs from a term loan that disburses a defined principal for scheduled repayment.
Businesses may use overdraft for temporary timing gaps between supplier, payroll or tax payments and customer collections. Individuals may see overdrafts linked to eligible deposits, salary relationships or other security under specific products. The facility should have a clear self-liquidating source; repeated use at the maximum indicates a structural funding problem.
The main costs can include interest on utilised balance, processing or renewal fees, charges on sanctioned or unutilised limits, security costs and penalties. A variable or on-demand structure creates repricing and renewal risk. Compare the complete annual cost with Working Capital Finance, Cash Credit and a term facility.
Use the Loan EMI Calculator only for a term-loan alternative; overdraft interest needs a utilisation-by-day model. Begin with the Loans hub and Budget Planner.

Actual lender steps, timelines and documents vary. Approval is complete only when communicated through the official lender process and all stated conditions are met.
An overdraft may be secured by a fixed deposit, property, receivables, inventory or another accepted asset, or may be unsecured under a specific product. Security, guarantee and account-control rights vary. The lender may review, reduce, freeze or recall the facility according to terms. Understand demand clauses and never assume the full limit is permanently available.
Assessment
Assessment may include account conduct, verified income or business turnover, cash conversion cycle, collection history, existing borrowing, credit profile, security, guarantees, requested limit and purpose. A high turnover does not prove free cash. Providers can require periodic information and renewal. Criteria and limits vary.
Use only the lender's verified branch, website or app. Never share an OTP, PIN, screen-access code or payment merely to ‘unlock’ approval.
Cost and repayment
Interest may be calculated on daily or periodic utilised balance under the contract, but processing, renewal, commitment, non-utilisation, inspection, documentation, security or delayed-payment costs may also apply. Ask for a complete fee schedule and the interest basis. Do not compare only the stated rate.
Build a daily or weekly cash calendar showing opening balance, draw, customer receipts and closing utilisation. Multiply the applicable daily balance by the contractual rate method for an educational estimate. Frequent deposits that are immediately withdrawn can create the appearance of turnover without reducing average use.
A limit that remains nearly fully drawn is functioning like a permanent loan but may have renewal and demand risk. Move long-lived machinery, renovation or structural debt to an appropriate term schedule rather than repeatedly rolling it through overdraft. Lower initial cash outflow is not lower total cost.
P is principal, R is the monthly interest rate and N is the number of monthly instalments. Approximate borrowing cost also includes total interest and applicable fees or charges. A lower EMI does not automatically mean a cheaper loan.
Balanced view
Borrow only when an eligible timing gap appears.
Lower utilisation can reduce interest under applicable terms.
Repaid amount may become available again within conditions.
Receipts can directly restore borrowing capacity.
Account activity shows reliance and peak gaps.
Different products may accept different support.
The limit may not remain available indefinitely.
Daily balance and rate movement affect interest.
A fully used limit can hide business losses.
Default can affect pledged assets and guarantees.
Stock, statements or routing requirements may apply.
Charges can apply beyond used-balance interest.

Illustrative example only
A fictional business has a ₹10,00,000 limit and uses the full amount for three months at a hypothetical 12% annual rate. This simplified illustration treats the amount as a three-month interest-only utilisation and excludes all fees.
If average use is only ₹5,00,000 because customer receipts reduce the balance, interest can be lower under a utilised-balance method. Actual daily balances, rate basis and fees determine cost.
Record days inventory is held, customer credit, supplier credit and collection delay. Identify the largest cumulative gap rather than requesting a round limit. Separate predictable seasonality from chronic losses. A limit based on peak sales can be excessive when margin or collections are weak.
Update opening cash, expected receipts, supplier, payroll, tax, rent and capital spending every week. Mark confirmed and uncertain receipts. Forecast limit usage and headroom. Compare forecast with actual and investigate missed collections immediately. This operational discipline is more useful than checking the balance only on a due date.
Where the contract requires or supports it, customer receipts should reduce overdraft before new draws. Do not divert collections to another account to make utilisation appear lower temporarily. Transparent account conduct supports control and accurate cost measurement. Reconcile interest and charges each statement cycle.
A late customer payment can be temporary; a business that loses money on every sale has no self-liquidating source. Machinery and expansion should use an appropriate Term Loan. If average utilisation rises month after month, reassess pricing, inventory, collections and facility design rather than requesting repeated increases.
Maintain current financial, tax, insurance, stock, receivable and security records as applicable. Know the review date and conditions. Stress a reduced or delayed renewal and keep a contingency plan for payroll and suppliers. Never assume an old limit renews automatically on identical terms.
A zero utilised balance does not necessarily close the sanctioned facility or release collateral. Submit formal cancellation, settle charges, collect no-dues and release security or guarantees. Confirm unused cheques, mandates and account controls are handled safely.
Choose internal warning points for average utilisation, days near maximum, overdue receivables and renewal headroom. Decide what action follows each trigger: collection calls, inventory reduction, expense delay, fresh equity or conversion of permanent use to term debt. Review triggers monthly with someone other than the person authorising payments. Early action is safer than treating available drawing power as proof that operations are healthy. Calculate interest as a share of gross margin, not only turnover. A business can appear active while finance cost consumes the surplus. Track customers responsible for the longest delays and change credit terms where commercially possible. Keep tax and payroll money distinct from available drawing power so routine statutory or employee obligations do not depend on last-minute lender headroom.
Early repayment
Depositing receipts generally reduces utilisation rather than functioning like term-loan prepayment. For permanent closure, request exact dues and fees, cancel the facility formally and obtain release of every security and guarantee. Preserve operating liquidity during the transition.
Avoidable errors
Sanctioned credit becomes routine spending.
Short revolving money supports a long asset.
Only the month-end balance is monitored.
The business depends on automatic continuation.
Borrowing does not self-liquidate as designed.
Facility and security remain active.
