Investment decisions and capital allocation
Clear definitions and practical examples to help you understand the numbers and decisions.
Capital allocation
Capital allocation is the choice of where a business commits scarce money and management capacity: a new asset, product launch, acquisition, debt repayment, working capital, or distribution to owners. The choice is not simply “which project has the highest return.” Funding one option can prevent the business from taking another.
Read the explanationInvestment appraisal
Investment appraisal is the disciplined assessment of a proposed investment before approval. It turns a commercial idea into dated incremental cash flows, assumptions, risks, and decision criteria. Methods such as net present value (NPV), internal rate of return (IRR), payback, and sensitivity analysis are tools inside that process, not substitutes for judgment.
Read the explanationBusiness case
A business case explains why a decision is requested, what alternatives are available, what the preferred option needs, and how success will be judged. It is broader than a financial model. The model estimates numbers; the case connects those numbers with customers, operations, people, timing, risks, and the owner who will deliver the result.
Read the explanationFeasibility study
A feasibility study tests whether a proposed project can actually be delivered in its intended market and operating setting. It examines the conditions that must be true: customer demand, technical capability, permits, suppliers, people, funding, timing, and economics. A project can be profitable on paper but infeasible because one of those conditions is absent.
Read the explanationFinancial model
A financial model is a structured set of inputs, calculations, and outputs used to estimate a business or decision’s financial consequences. It can connect volume, price, costs, working capital, tax, funding, and cash so that a change in one assumption reaches the relevant outputs.
Read the explanationThree-statement model
A three-statement model links the income statement, balance sheet, and cash flow statement. Revenue and costs affect profit; profit, investment, borrowing, and working capital change assets, liabilities, and equity; those movements explain the change in cash. The links force the forecast to tell one consistent story.
Read the explanationTime value of money
The time value of money recognises that a riyal available today is different from a riyal received later. Cash held today can be used, invested, or kept available for an obligation. Future cash also carries timing, inflation, and collection risk. For that reason, investment decisions compare dated cash flows rather than simply adding their nominal amounts.
Read the explanationPresent value
Present value is the value today of a future cash flow after applying a discount rate for the time and risk between today and receipt. For one annual period, present value equals future cash divided by one plus the discount rate. The discount factor is the reciprocal of that denominator.
Read the explanationFuture value
Future value is the amount that cash available today will grow to after compounding at a stated rate for a stated number of periods. For annual compounding, future value equals today’s amount multiplied by one plus the annual rate for each year. It answers the opposite question from present value: instead of bringing future cash back to today, it moves today’s cash forward.
Read the explanationDiscount rate
A discount rate is the rate used to convert future cash flows into present values. It represents the return required for deferring cash and bearing the risk reflected in the forecast. It should be chosen to fit the currency, timing, inflation basis, and risk of the cash flows being discounted.
Read the explanationCost of capital
Cost of capital is the return that lenders and owners require for committing money to a business. It reflects what they could earn elsewhere and the risk, timing, currency, and liquidity of the funds they provide. Management uses it as a hurdle or as an input to a discount rate when it compares investments.
Read the explanationWeighted average cost of capital
Weighted average cost of capital, or WACC, combines the required return on equity with the after-tax cost of debt using their weights in the capital structure. It is commonly used to discount cash flows that have risk similar to the company’s existing operations. The debt component is normally after tax because interest can reduce taxable profit where that tax benefit is available.
Read the explanationNet present value
Net present value, or NPV, asks a simple question: after allowing for when cash arrives and the return required for its risk, does a project add value today? It is the present value of all relevant future incremental cash inflows less the present value of all relevant cash outflows.
Read the explanationInternal rate of return
Internal rate of return, or IRR, is the discount rate at which the present value of a project’s future cash inflows equals its initial outflow, so net present value is zero. It expresses one possible return implied by a particular pattern of cash flows. Management often compares it with a required return, but the comparison is useful only after the cash flows and timing have been scrutinised.
Read the explanationPayback period
Payback period is the time required for cumulative cash inflows to recover an initial investment. It answers a liquidity question: how long is capital exposed before the project has returned the amount put in? The usual version uses undiscounted cash, so it is simple to explain and useful when survival, funding capacity, or uncertainty beyond the early years matters.
Read the explanationDiscounted payback period
Discounted payback period is the time required for the present value of a project’s cash inflows to recover its initial outlay. It improves on simple payback by discounting each future cash flow at a stated required return before adding it to the cumulative recovery. The result therefore gives a more realistic view of how long capital remains unrecovered in today’s value.
Read the explanationProfitability index
Profitability index, or PI, divides the present value of future project cash inflows by the initial investment. A PI above 1.0 means that discounted inflows exceed the outlay and the project has positive NPV at the chosen rate; a PI below 1.0 means they do not. It can help rank divisible investments when capital is rationed because it shows value per unit of capital committed.
Read the explanationReturn on investment
Return on investment, or ROI, measures a stated gain relative to a stated investment. A common project formula is gain divided by investment, expressed as a percentage. It is useful as a compact summary only when the organisation is explicit about what counts as the gain, what costs are included, the period covered, and whether the figure is cash-based or accounting-based.
Read the explanationSensitivity analysis
Sensitivity analysis changes one input at a time while holding the other stated assumptions constant, then observes the effect on an output such as NPV, cash balance, or break-even volume. It does not predict the future. It reveals which assumptions deserve the most evidence because a plausible movement in them would change the recommendation.
Read the explanationStress testing
Stress testing asks what happens when several adverse but plausible conditions occur together. Unlike one-way sensitivity analysis, it combines drivers that may move at the same time: lower volume, delayed collection, higher input cost, unavailable finance, or a slower ramp-up. Its purpose is not to assign a precise probability. It is to expose the point at which the business loses liquidity, breaches a commitment, or can no longer execute the plan.
Read the explanationCapital rationing
Capital rationing occurs when a company has a fixed limit on the capital it can deploy, so it cannot accept every project with positive NPV. The constraint may be hard, such as unavailable external finance or a covenant limit, or soft, such as a temporary management-capacity limit. The decision becomes a portfolio problem: which feasible combination creates the most value while respecting cash timing, risk, dependencies, and execution capacity?
Read the explanationTerminal value
Terminal value estimates the value of cash flows after an explicit forecast ends. In a discounted cash-flow valuation it can be based on a stable-growth formula or an exit assumption, then discounted back with the forecast cash flows. It often represents a large share of total value, so it must be visible rather than treated as a spreadsheet remainder.
Read the explanationPost-investment review
A post-investment review compares an approved investment case with actual results after implementation. It asks whether the project delivered the cash, benefits, timing, risks, and operating changes that justified approval, and why material differences occurred. Its purpose is to improve future decisions and execution, not to punish a forecast for being uncertain.
