Financial and Economic Modelling
A useful model connects operating assumptions to financial consequences and makes uncertainty visible. IDER develops financial and economic models for businesses, projects and public-sector decisions, using a structure that clients can interrogate and update. We translate demand, pricing, costs, investment and financing assumptions into cash flows, performance measures and scenarios, supporting decisions about capital allocation, funding, affordability and wider economic value.
The decision challenge
Spreadsheets can appear precise while concealing weak assumptions, inconsistent calculations or unexplained links. Decision-makers need models that show what drives results, how funding choices affect cash flow and whether conclusions hold under changing demand, costs, timing and other relevant conditions.
Questions we help you answer
- Which operating and financing assumptions drive performance and cash requirements?
- How do alternative investment, funding or policy scenarios compare?
- What financial and wider economic effects follow from the proposed decision?
What the research covers
How we build the evidence
- Driver-based modelling of revenue, expenditure, working capital and capital investment
- Integrated financial-statement construction and cash-flow reconciliation
- Discounted cash-flow and economic cost-benefit analysis with explicit assumptions
- Sensitivity, scenario and probabilistic analysis where the evidence supports it

What this enables you to decide
Compare investment and funding options, understand liquidity pressures and identify the assumptions that deserve closer attention. The model supports an informed decision by showing how results change; its projections remain conditional on the underlying evidence and assumptions.
Quality and interpretation
We document units, periods, sources and calculation logic; apply reconciliation and reasonableness checks; and separate observed inputs from estimates. Sensitivity analysis, model limitations and review notes help users interpret outputs without treating forecasts as certainty.
