Finance and accounts
IB Diploma Programme Business Management HL, Unit 3 Finance and accounts
(first assessment 2024). This topic covers sections 3.1 to 3.9: why
businesses need finance and where they get it, costs and revenues, final
accounts, ratio analysis, cash flow, investment appraisal and budgets.
Debt/equity ratio analysis (3.6), budgets (3.9), net present value,
intangible assets and depreciation are HL only. The worked examples use the
course's repair business in its second year as a company, so every number
below fits with every other.
In 2017 the bike-sharing company ofo had millions of yellow bikes on the
streets of Chinese cities and had raised billions of dollars from investors.
By the end of 2018 it had spent most of that money, and more than ten
million users were waiting in an online queue to get their deposits back.
Customers liked the product. The company failed because cash ran out. This
topic shows how a business plans its money, reads its accounts and checks
whether a project is worth the cost.

3.2
Finance and its sources
A business spends money in two ways.
Capital expenditure 资本支出 buys non-current assets 非流动资产,
things the business keeps for more than a year: a workshop, a machine, a
van.
Revenue expenditure 收益支出 pays for day-to-day running: wages,
parts, rent and electricity.
The money for each should come from a source that fits. A long-term asset
needs long-term finance. Paying for a new workshop with an overdraft is
risky, because the bank can ask for the overdraft back at any time.
Internal finance comes from inside the business; external finance comes from outside
Internal finance 内部融资 comes from inside the business:
personal funds 个人资金: the owner's own savings, the main source for
a sole trader;
retained profit 留存利润: profit kept in the business instead of
being paid to the owners. It costs no interest, but a new or loss-making
business has none;
the sale of assets 出售资产 the business no longer needs, such as an
old van.
External finance 外部融资 comes from outside:
Source
What it is
For and against
share capital 股本
money from selling shares (companies only)
never repaid and no interest; the owners lose some control
loan capital 贷款资本
a bank loan repaid with interest over years
large sums; interest must be paid even in a bad year
overdraft 透支
the bank lets the account go below zero
flexible and quick; expensive, and the bank can end it at any time
trade credit 商业信用
suppliers let the business pay 30 to 60 days later
free; paying late harms the relationship
crowdfunding 众筹
many people each give a small amount online
also tests the idea; most campaigns fail to reach their target
leasing 租赁
renting equipment instead of buying it
no large payment; costs more in total
microfinance 小额信贷
small loans to people that banks will not serve
helps very small and new businesses; amounts are small
business angels 天使投资人
rich individuals who invest and give advice
money plus experience; they want a share of the business
Sources are also short term (under a year: overdraft, trade credit), medium
term (one to five years: leasing, most loans) or long term (over five
years: share capital, long loans). To choose, a manager weighs the cost,
the amount needed, how long it is needed for, control of the business, and
how much the business has already borrowed.
Worked example. The repair business built a second workshop for
120,000. Half came from retained profit and half from a five-year bank loan.
The workshop will earn money for many years, so long-term finance fits. The
monthly parts bill uses trade credit. For eleven days in December, when
wages were paid before customers paid their bills, the business used its
overdraft.
A fixed cost 固定成本 does not change with output: rent, salaries,
insurance.
A variable cost 可变成本 changes with output: car parts, paint,
energy for the machines.
A semi-variable cost 半可变成本 has a fixed part and a variable part,
such as a phone contract with a monthly charge plus a cost per call.
A direct cost 直接成本 belongs to one product or department, such as
the parts used in one repair. An indirect cost 间接成本, or
overhead 管理费用, is shared, such as the manager's salary.
Total revenue 总收入 is price × quantity sold. The repair business does
2,000 repairs a month at an average price of 25, so its revenue is
$2{,}000 \times 25 \times 12 = 600{,}000$ a year. Many businesses also
have other revenue streams 收入来源: the repair business sells tyres,
rents out its car wash and earns a fee from an insurance company for every
customer it sends.
Final accounts
The final accounts 财务报表 are prepared at the end of each year. Many
stakeholders 利益相关者 read them: owners and shareholders check
profit, banks check the business can repay, suppliers check it can pay its
bills, employees check their jobs are safe, and the government checks tax.
The income statement 损益表 shows how much profit the business made
over the year.

Brackets mean the number is taken away. Cost of sales 销售成本 is the
direct cost of the repairs that were sold: opening stock 18,000, plus parts
bought 372,000, minus closing stock 30,000, gives 360,000.
The statement of financial position 资产负债表, or balance sheet, is a
picture of the business on one day: what it owns (assets 资产), what
it owes (liabilities 负债) and the owners' money (equity 所有者权益).
current assets: stock 30,000; debtors 45,000; cash 5,000

Current assets 流动资产 turn into cash within a year. Debtors应收账款 are customers who still owe money. Current liabilities流动负债 must be paid within a year; creditors 应付账款 are suppliers
the business still owes. Current assets minus current liabilities is
working capital 营运资本: $80{,}000 - 40{,}000 = 40{,}000$, the money
available for day-to-day running. Net assets always equal equity, because
everything the business owns is paid for either by borrowing or by the
owners.
The balance sheet balances: total assets of 400,000 are paid for by equity, long-term debt and short-term debt
Intangible assets and depreciation (HL)
An intangible asset 无形资产 has value but cannot be touched: a brand,
a patent 专利, a copyright, a trademark, or goodwill 商誉 (the
extra a buyer pays for a business's reputation and customers). They are
hard to value, and the value can fall fast after a scandal.
Depreciation 折旧 is the fall in value of a non-current asset as it is
used and gets older. It spreads the cost of the asset over its life and is
counted as an expense each year. The repair business buys a diagnostic
machine for 22,000. It expects to use it for 4 years and then sell it for
2,000, its residual value 残值.
Straight-line method 直线法:
$\dfrac{\text{cost} - \text{residual value}}{\text{years of life}} = \dfrac{22{,}000 - 2{,}000}{4} = 5{,}000$
a year, the same every year.
Units of production method 工作量法: the machine is expected to do
20,000 tests in its life, so each test costs
$(22{,}000 - 2{,}000) \div 20{,}000 = 1$. In a year with 6,000 tests,
depreciation is 6,000. This method fits machines that are used more in
some years than in others.
$$\text{profit margin} = \frac{\text{profit before interest and tax}}{\text{sales revenue}} \times 100 = \frac{90{,}000}{600{,}000} \times 100 = 15\%$$
Capital employed 运用资本 is non-current liabilities plus equity:
$160{,}000 + 200{,}000 = 360{,}000$.
$$\text{ROCE} = \frac{\text{profit before interest and tax}}{\text{capital employed}} \times 100 = \frac{90{,}000}{360{,}000} \times 100 = 25\%$$
The return on capital employed 资本回报率 (ROCE) of 25% is far above
the roughly 6% interest on the bank loan, so borrowing to invest has paid
off. To raise profitability, a business can raise prices where customers
are loyal, buy parts more cheaply, cut waste, or sell more of its
high-margin services.
Liquidity ratios 流动性比率 show whether the business can pay its
short-term debts.
A current ratio between 1.5 and 2 is usually safe. The acid test ratio速动比率 leaves out stock, because stock may be slow to sell; a result
above 1 is usually safe. Both results here are healthy. A ratio far above
the safe range is not good either: money is sitting idle instead of
earning a return. To improve liquidity, a business can sell old stock,
collect money from debtors faster, or turn an overdraft into a long-term
loan. Each step has a cost: discounts to sell stock lower profit, and
pushing customers to pay faster may lose some of them.

3.5
Efficiency ratios and gearing (HL)
Efficiency ratios 效率比率 show how well the business manages its stock
and its credit. Average stock is (opening stock + closing stock) ÷ 2
$= (18{,}000 + 30{,}000) \div 2 = 24{,}000$.
$$\text{stock turnover} = \frac{\text{cost of sales}}{\text{average stock}} = \frac{360{,}000}{24{,}000} = 15 \text{ times a year}$$
or, in days, $\dfrac{24{,}000}{360{,}000} \times 365 = 24.3$ days. The
business sells and replaces its stock of parts about every 24 days. Faster
stock turnover 存货周转率 frees cash; too little stock means customers
wait for parts.
Debtor days 应收账款天数 is how long customers take to pay;
creditor days 应付账款天数 is how long the business takes to pay its
suppliers. Here customers pay about two days more slowly than the business
pays its suppliers, so the business pays out before it is paid. It could
ask insurance companies to pay within 20 days, or ask suppliers for 45-day
terms.
The gearing ratio 资本负债率 shows how much of the long-term finance is
borrowed. Above 50% a business is usually called highly geared. High
gearing is risky: interest must be paid even when sales fall, and banks
may refuse more loans. When profit is strong, though, borrowing lets the
owners earn more without giving away shares. At 44.4% the repair business
is close to the line, so its next project should be paid for with share
capital or retained profit, not another loan.
Profit 利润 and cash flow 现金流 are different. Profit is revenue
minus costs for the year. Cash flow is the money that actually comes in and
goes out, and when. A repair finished on 28 December counts as revenue in
December, but if the customer pays in February, the cash arrives in
February. A profitable business can still fail if it has no cash to pay
wages and suppliers. A business with cash can survive a loss-making year.
The working capital cycle 营运资本周期 is the time between paying for
inputs and receiving cash from customers.
The longer the working capital cycle, the more cash the business needs to keep running
Businesses hold cash for three reasons: to pay day-to-day bills, to keep a
safety reserve for surprises, and to take chances when they come, such as
a supplier's discount for buying in bulk.
A cash flow forecast 现金流量预测 shows the cash a business expects to
receive and pay out, month by month. Each month:
net cash flow = cash in − cash out;
closing balance = opening balance + net cash flow;
the closing balance becomes next month's opening balance.
Worked example. The repair business forecasts the first half of next
year (in $000).

In April the yearly insurance and a large parts order are paid in the same
month, and the balance falls to −5,000. The forecast shows the problem in
January, so the manager has three months to arrange an overdraft or move a
payment.
The closing balance falls below zero in April and May: the forecast warns of a cash shortage three months early
A forecast is only as good as its guesses. Sales may be lower than
expected, customers may pay late, and costs may rise. Managers should
change it as new information comes in.
A business can deal with a cash flow problem in three ways:
Approach
Examples
Drawback
reduce cash outflows
delay buying new equipment; lease instead of buy; ask suppliers for longer credit
old equipment may break; suppliers may refuse
improve cash inflows
ask customers to pay faster; offer a discount for paying cash; sell old stock
discounts lower profit; customers may go elsewhere
find more finance
overdraft; short-term loan; sell an asset
interest costs; the asset may be needed later
Investment, profit and cash flow are linked. A new workshop uses a lot of
cash now and earns profit only later, so even a good investment can cause
a cash shortage in its first months.
Investment appraisal 投资评估 checks whether a capital project is worth
its cost. The repair business plans a third workshop. It costs 120,000 and
should bring in a net cash flow of 40,000 a year for four years.
The third workshop pays back its 120,000 cost after exactly three years
The payback period 投资回收期 is the time a project takes to earn back
its cost. After three years the workshop has earned
$3 \times 40{,}000 = 120{,}000$, so the payback period is 3 years. If the
cash flow is not the same each year, add the years until the total covers
the cost, then work out the part year: months $= \dfrac{\text{amount still needed}}{\text{cash flow in that year}} \times 12$.
Payback is simple and shows risk, because money that comes back sooner is
safer. It ignores everything that happens after the payback date.
The average rate of return 平均收益率 (ARR) is the average yearly profit
as a percentage of the cost.
ARR uses all the years of the project and can be compared with the
interest rate on a loan. It ignores timing: 40,000 received in year 4 is
treated the same as 40,000 received in year 1.
Net present value (HL)
Money received in the future is worth less than money today, because money
today could be saved and earn interest. Net present value 净现值 (NPV)
turns each future cash flow into its value today with a discount
factor 折现系数, then subtracts the cost. At a discount rate of 6%:

NPV $= 138{,}600 - 120{,}000 = +18{,}600$. A positive NPV means the
project earns more than the 6% the money could earn elsewhere, so it is
worth doing. NPV counts timing, but the result depends on the discount
rate chosen, and it is harder to explain to non-specialists.
All three methods depend on forecasts of cash flow, which may be wrong.
Managers also weigh things the numbers leave out: the effect on staff,
the business's image, and the risk that a rival opens nearby.
A budget 预算 is a financial plan for a future period, such as next
year's sales or costs for one workshop. A forecast predicts what will
happen; a budget sets a target for what should happen. Budgets help a
business plan, share out resources, give managers clear targets, and
check results.
A cost centre 成本中心 is a part of the business whose costs are
recorded, such as the repair business's IT department. A profit centre利润中心 has both costs and revenues recorded, so its profit can be
measured, such as each workshop. Profit centres show which parts do well,
but they can make managers compete with each other instead of working
together.
A variance 差异 is the difference between the budget and the actual
result. It is favourable 有利 (F) when it raises profit and adverse不利 (A) when it lowers profit.
Worked example. Workshop 3, one month:

Revenue rose because the workshop cut its price to win more repairs. But
the extra repairs needed more parts, and parts became dearer, so profit is
60 below budget. A manager should find the cause of each variance before
acting: was the price cut a good decision, or did parts cost more because
of a new supplier? Used this way, budgets and variances feed back into
the business's plans for next year.

Scope and prerequisites
IB business management first assessment 2024. Business research project investigates one real organization through a conceptual lens. The toolkit and change, creativity, ethics and sustainability connect units; HL-only topics remain marked.
Mapped preparation outcomes: ib_business_management_hl.3.1, ib_business_management_hl.3.2. Read the matching native lesson first. Actual approved choices, evidence and final learner work remain separate.
Source vocabulary
cash flow 现金流; liquidity 流动性.
Explanation and worked method
Profit records revenue and expenses; cash flow records receipts and payments. A profitable sale on credit may not supply cash today. Match finance duration, cost, control and repayment to the need. Appraisal must state forecast assumptions and uncertainty.
Original case: opening cash 1,500 currency units, receipts 2,800, payments 3,600. Compute closing cash and evaluate paying 900 for equipment immediately.
Net cash flow=receipts−payments=2,800−3,600=−800 units. Closing cash=opening cash+net cash flow=1,500−800=700 units. An immediate 900-unit purchase creates a 200-unit cash gap unless other timings or finance change. Forecast later receipts, consider staged purchase or suitable finance and compare repayment with expected benefits. A positive accounting profit cannot resolve this timing gap.
Independent transfer
Project A repays sooner; project B produces larger later inflows. Is payback sufficient for choosing?
Attempt independently before reading the model.
Checked original model
Payback indicates recovery time and liquidity exposure but ignores later flows and, in its simple form, time value. Compare relevant appraisal measures, forecast reliability, finance and strategic fit. Neither larger total cash nor quicker recovery alone decides every context.
These are authored formative expectations, not official IB descriptors. Accept other justified arguments with evidence and material limits.
