Sources of finance and interest

🎬 The doodle video for this lesson is coming soon. Subscribe on YouTube to see it first.

Businesses need money to start and to grow. Each source of finance suits different situations.

Short-term sources

Overdraft: take more money out of a bank account than you have, up to a limit. Flexible, but high interest.
Trade credit: buy now from suppliers and pay later, often within 30 to 90 days.

Long-term sources

Personal savings: no interest, but the owner risks their own money.
Venture capital: investors give money in exchange for a share of the business.
Share capital: selling shares in the business.
Loans: borrow a fixed sum and repay with interest.
Crowdfunding: many people each give small amounts, often online.
Retained profit: profit kept in the business from earlier years.

Interest on loans

Interest (%) = (total repayment − amount borrowed) ÷ amount borrowed × 100
Worked example

A business borrows £5000 and repays £5600 in total. Find the interest rate.

  1. Interest paid = 5600 − 5000 = £600
  2. 600 ÷ 5000 × 100
  3. = 12%

Answer: 12%

Key idea

Short-term: overdraft, trade credit. Long-term: savings, venture capital, shares, loans, crowdfunding, retained profit. Interest % = (repayment − borrowed) ÷ borrowed × 100.
