DCF vs Multiples: When to Use Which, and Why You Need Both

Founders and chief executives preparing a valuation for a fundraise, an exit, or an EMI share scheme almost always ask the same question: should the valuation be built on discounted cash flow, or on multiples?

The most accurate answer, and the one consistent with IVSC IVS 105, is that a defensible business valuation normally requires both. A single-method valuation is rarely robust enough to survive investor diligence, acquirer scrutiny or review by HMRC Shares and Assets Valuation. The skill lies in knowing when the cash flow model should carry more weight, when the market evidence should lead, and how to reconcile the two into a range you can stand behind.

This matters particularly for technology businesses. Valuing a UK SaaS company, a marketplace or a fintech means valuing growth, recurring revenue and forward-looking uncertainty at the same time. In those conditions, neither method is usually sufficient alone.

Why the debate matters

The two approaches answer related but different questions.

A discounted cash flow estimates intrinsic value by projecting future cash flows and discounting them to today. It is only ever as strong as the forecast behind it and the discount rate applied to it, and both are open to challenge.

Multiples estimate value by reference to what comparable companies and completed transactions are actually priced at. They are only as strong as the relevance of the comparable set, and a poorly matched peer group produces a number that looks objective and is not.

A valuation that runs both and explains where they converge, or why they do not, is materially harder to argue with. That matters most where the number will be tested from several directions at once: a fundraise, a sale, or a formal HMRC submission.

When cash flow should lead

The discounted cash flow tends to be the stronger primary method in three situations.

**The business has a credible multi-year forecast.** Where management can support revenue drivers, retention, margins, hiring and cash conversion with stated assumptions, the model becomes genuinely informative rather than decorative. This is common in growth-stage SaaS, and in fintech once unit economics are visible.

The discipline that makes the difference is the discount rate. A cost of capital assembled from a documented risk-free rate, an equity risk premium and a relevered beta can be defended line by line. One asserted as a round number cannot, and it is usually the first thing a diligence team asks about.

**The comparable set is thin, dated or poorly matched.** In emerging niches and specialised verticals, public and transaction comparables may barely exist. Forcing a multiples conclusion there manufactures false precision. The cash flow model gives an independent view that does not depend on finding peers that are not there.

**The company is in transition.** A SaaS business recovering from elevated churn, a marketplace improving liquidity, a fintech moving from investment mode toward profitability, or any company commercialising significant research. Trailing multiples systematically misread these situations, because they price the position the company is leaving rather than the one it is reaching.

Most growth-stage SaaS businesses meet at least one of those conditions, which is why the cash flow model usually leads in that work, particularly where the company is preparing to raise or to sell.

When multiples should lead

The market evidence deserves greater weight in three corresponding cases.

**The comparable set is dense and current.** Where there are enough relevant listed peers publishing transparent metrics, market pricing becomes highly informative, and arguing against it requires a reason. This is more common in established SaaS categories and in parts of fintech.

**The business is mature and financially stable.** Predictable margins, lower growth volatility and clearer earnings power all make an EV/Revenue or EV/EBITDA conclusion more reliable, and reduce how much work the forecast has to do.

**The question is strategic rather than intrinsic.** A trade buyer rarely arrives with a cash flow model. They arrive with a multiple, drawn from what they or their competitors last paid. A valuation that ignores the prevailing range has to work considerably harder to be believed, however sound its internal logic.

That last point is worth stating plainly, because it is the one founders most often underestimate. Multiples matter partly because they are correct and partly because they are the language the market negotiates in. A board, an acquirer and an investor will each arrive with a figure already in mind.

How the balance shifts by sector

The principles hold everywhere. What changes is the weighting.

SaaS

Growth-stage SaaS leans on the cash flow model, because value is driven by future retention, expansion and margin progression rather than by the current year's revenue. Current market multiples remain essential as a cross-check: if the model concludes far outside the range comparable businesses are trading at, that gap needs explaining rather than ignoring.

Marketplace

Marketplaces are more sensitive to liquidity, take rate and network effects. Where cohort behaviour and contribution margin are genuinely forecastable, the cash flow model is strong. Where relevant transactions or listed peers exist, they anchor the market view. Both perspectives matter here, because the two can disagree sharply and the disagreement is usually informative.

FinTech

FinTech valuations vary more widely by model than any other sector we work in. Payments, lending, infrastructure, wealth and embedded finance are priced on different bases and are not interchangeable. Some support strong intrinsic analysis once unit economics stabilise; others are still valued primarily on revenue or gross profit. A careful fintech valuation tests both and states which is leading.

Why triangulation produces a defensible business valuation

A valuation presenting only one method leaves the obvious question unanswered.

Cash flow alone invites the criticism that it is assumption-driven, and that a different set of equally plausible assumptions would produce a different number. Multiples alone invite the criticism that they were applied mechanically to a peer group that does not really match.

Running both, comparing the outputs and explaining the difference addresses both objections at once. This is also the standard expected in formal contexts such as EMI and HMRC share valuations, where the methodology and the reasoning are examined as closely as the figure.

In practice it improves credibility with investors during a raise, acquirers during a sale, HMRC in share scheme work, and boards who need a balanced view rather than an advocate's number.

The football-field reconciliation

The clearest way to present triangulation is a football-field chart, showing the range implied by each method on a single page.

Where the ranges overlap, that overlapping zone is usually the most defensible conclusion, because more than one line of evidence supports it. Where they diverge, the analyst has to explain why, and that explanation is frequently the most valuable page in the report. A wide divergence is not a failure of the work; it is a finding about the business, and it usually points at the assumption doing the most work.

This is consistent with our methodology and with IVS 105, and it is what experienced diligence teams expect. A report showing one method and no reconciliation is straightforward to challenge.

What buyers and investors actually test

In exit-readiness work and in technology transactions generally, the recurring areas of scrutiny are:

• The quality of recurring revenue
• Retention and expansion dynamics
• Margin structure and the path to profitability
• Customer concentration
• The credibility of the forecast
• How the valuation was derived, and whether it holds together across methods

That final point is the one this article is really about. A valuation defensible from only one direction is fragile, and diligence teams are practised at finding the direction you did not cover.

Practical implications

If you are preparing a valuation for a fundraise, a sale, or an EMI grant:

• Do not rely on a single method
• Lead with cash flow where forecast quality or a business in transition makes intrinsic analysis meaningful
• Lead with multiples where the market evidence is dense and genuinely comparable
• Reconcile the two, and state the weighting rather than leaving it implicit
• Present the conclusion as a reasoned range, not a lone figure

How we approach it

Every ValuCap valuation is triangulated by default. A typical engagement runs a three-scenario discounted cash flow, comparable company analysis and precedent transaction analysis, reconciles them through a football-field presentation, and weights them according to business stage, sector and the quality of available evidence.

The conclusion is a reconciled range with the reasoning attached. For SaaS, marketplace and fintech companies the weighting is adjusted to reflect the economics of the model and the multiples currently observable in each sector.

Final thought

The choice between the two is usually a false one. A serious valuation does not pick a method and ignore the alternative. It runs both, tests where they agree, investigates where they do not, and presents a conclusion that can be defended from more than one direction.

That is what makes a valuation useful in a fundraise, credible in a sale, and robust when it comes under formal scrutiny.
