Line of Credit for Small Business Explained

An educational guide to business lines of credit, including utilisation, cost, flexibility and repayment discipline.

A line of credit is a revolving facility that provides access to funds up to an approved limit. It can be useful where funding needs move up and down, but the business should understand how the drawdown will be repaid and whether fees apply even when the facility is lightly used.

Overview

Start with the business outcome.

A line of credit is a revolving facility that provides access to funds up to an approved limit. It can be useful where funding needs move up and down, but the business should understand how the drawdown will be repaid and whether fees apply even when the facility is lightly used.

Comparison

Potential advantages and trade-offs.

Why a business may consider finance

  • Flexible access for variable working-capital needs
  • Potential to repay and redraw within the facility terms
  • Can provide contingency headroom without drawing the full amount
  • Often better aligned with recurring cycles than repeated term loans

What the business gives up

  • Variable rates and fees can change the cost
  • The limit may be reviewed or reduced
  • Permanent usage can signal that the facility is solving the wrong problem
  • Strong internal controls are needed to prevent casual spending

Model the decision.

Adjust the assumptions to see how the structure changes liquidity, repayment pressure or estimated cost. The output is educational and intentionally conservative.

Simple estimate only. Product terms may include establishment, line, review, transaction, minimum-interest or unused-limit fees.

Practical example

Put the structure into context.

Illustrative scenario

An importer may draw a line for freight and stock arrival costs, then repay it as inventory is sold and customer cash is collected.

Balanced decision

When cash or finance may fit.

Paying cash may fit when

Using cash may be simpler for infrequent minor gaps that do not threaten the operating buffer.

Finance may fit when

A line of credit may fit where the need is recurring, temporary and supported by a clear conversion back into cash.

A blended structure can also be considered—for example, contributing a deposit from surplus cash while financing the long-lived asset and retaining an operating buffer.

FAQs

Frequently asked questions.

What is utilisation?

It is the proportion of the approved limit that is actually drawn.

Why does utilisation matter?

It affects interest cost and may reveal whether the limit is appropriately sized.

Can a line fund a long-term asset?

A dedicated asset or term facility may better match a long-lived purchase.
