Short intro
Value for money is one of the most cited but least well explained requirements in donor and government procurement. Evaluators are not asking for academic papers; they want a defensible, transparent explanation that links what you propose to measurable outputs and reasonable costs. This post sets out practical analyses you can include in a bid, how to present them so evaluators can score them, and how to convert a VFM narrative into contractual controls during delivery.
What evaluators actually look for
Donors use the phrase value for money in different ways, but common expectations are consistent. Keep your explanation targeted to these points:
- A clear statement of the outcome you intend to achieve and the unit of measurement for that outcome. Examples: additional households connected, student learning months, treated hectares.
- A transparent cost per unit, showing how you calculated it and what is included or excluded.
- Evidence that the chosen approach is cost-effective compared with plausible alternatives.
- An assessment of risk and uncertainty, with sensible sensitivity analysis.
- Mechanisms in the contract and implementation plan that protect funder interests if performance or costs change.
If your submission does not provide these elements in a compact, verifiable form, evaluators will downgrade the VFM score even if the technical approach is strong.
Practical analyses to include in the bid
You do not need complex econometrics. Simple, transparent calculations beat opaque models every time. Useful analyses include:
- Unit-cost comparators
- Calculate cost per outcome for your proposal and for at least one credible alternative. Be explicit about numerator and denominator definitions and time horizons.
- Cost-effectiveness ratio
- For interventions with a single clear outcome, present cost per unit outcome and rank alternatives if possible.
- Cost-benefit sketch
- When monetisation is feasible, provide a conservative benefit estimate and a sensitivity range. Be explicit about discount rates and assumptions.
- Lifecycle costing
- Show mobilisation, recurrent, maintenance and closure costs over the contract period, and indicate who bears each cost.
- Risk-adjusted costs
- Present a base cost and an adjusted cost that accounts for identified delivery risks, with probabilities or qualitative multipliers.
- Sensitivity analysis
- Change the key assumptions (unit cost, uptake, time to impact) and show how the cost per outcome moves. Use 2-3 realistic scenarios.
Make the calculations simple tables or short annexes. Evaluators prefer readable evidence to long technical notes.
How to present VFM so evaluators can score it
Organisation and clarity improve scoring. Use a single VFM annex with the following structure:
- Executive summary: one paragraph stating the chosen metric, the headline cost per unit, and why the approach is preferred.
- Assumptions table: list each material assumption, its source, and sensitivity.
- Comparative table: show your proposal and at least one alternative on the same metrics.
- Calculation worksheet: show step-by-step how you derived the unit cost and any ratios.
- Risk register summary: link principal risks to potential cost impacts and mitigations.
- Evidence references: cite sources for prices, productivity rates, or comparator studies.
Formatting tips
- Use consistent units and time horizons.
- Label every number with a source or a conservative assumption tag.
- Avoid hidden allocations by putting overheads, contingencies and indirect costs in the worksheet and explaining why they are needed.
- Where possible, visualise: one table and one chart are more effective than several pages of text.
Remember that evaluators are short of time. If they can understand your VFM case within two minutes they will annotate it positively and accept details in annexes.
Link VFM to contract design and delivery
A VFM statement in the proposal is weaker unless contract mechanisms reinforce it. Demonstrate how you will protect VFM during delivery:
- Payment mechanisms aligned to outcomes
- Where appropriate, propose milestone or results-linked payments that align incentives. Describe measurable indicators and data collection arrangements.
- Price adjustment rules
- For long contracts include clear indexation, force majeure and change-control provisions so price movements do not create perverse incentives.
- Performance monitoring
- Describe what data you will collect, how often, and who will audit results. Include an independent verification clause where feasible.
- Cost control and audit trails
- Explain internal controls, procurement rules for subcontracting, and reporting that enable the donor to verify incurred costs.
- Learning and adaptation
- Show a mechanism to use early results to adjust scale or approach, with transparent criteria and limits to change.
Tie these instruments back to the VFM calculations. For example, if unit cost depends on achieving a 70 percent uptake, show what contract actions you will use if uptake falls below that threshold.
Common pitfalls and how to avoid them
- Overcomplicating the model
- Long, opaque spreadsheets reduce trust. Keep the public-facing worksheet short and move complex sensitivity tables to an annex.
- Hiding assumptions
- If evaluators cannot find the logic behind a number they will assume it is optimistic.
- Comparing apples with oranges
- Ensure comparators use the same scope and time horizon. If you cannot find a perfect comparator, explain differences and adjust accordingly.
- Ignoring risk
- Presenting a single point estimate without showing downside scenarios signals poor risk management.
- Confusing cost minimisation with value for money
- The cheapest option is not always best; link costs to outcomes and explain trade-offs.
Takeaways
- Define the outcome metric and present a clear cost per unit with sources and assumptions.
- Use simple comparative tables and one-page executive summaries that evaluators can read quickly.
- Include sensitivity and risk-adjusted costs to show realism and robustness.
- Link VFM calculations to contract design: payments, monitoring, price adjustments and verification.
- Keep annexes transparent, auditable and consistent with the main proposal narrative.
A defensible VFM case increases both technical scores and confidence in your ability to deliver. Make transparency your guiding principle and evaluators will reward clarity over cleverness.
