Forecasting Intelligence is the part of ElenIQ that models what spend changes will do. Upload your historical campaign data and it fits response curves per channel, models diminishing returns and saturation, and forecasts revenue, ROAS, leads and CPL with prediction intervals - replacing fixed spreadsheet assumptions with confidence-scored forecasts you can plan against.

The problem

Budgets move on averages. Returns happen at the margin.

Most plans assume the next pound performs like the last one. It rarely does: channels saturate, efficiency decays as spend scales, and a shift in one channel changes what the others deliver.

When the forecast is a spreadsheet with a fixed ROAS, the first time anyone sees the real response is after the money has been spent - and the explanation to the client or the CFO is written in hindsight.

  • Average ROAS hides saturation

    A channel can look efficient overall while the next increment of spend returns far less.

  • Scenarios are slow to build

    Testing three budget options by hand takes days, so most plans only ever test one.

  • Recommendations lack a why

    A number without its drivers is hard to defend in a budget review.

  • Uncertainty is invisible

    A single point forecast gives no sense of the range you are actually planning against.

Inside Forecasting

Test the budget shift before you make it.

The scenario planner compares your baseline plan with a proposed reallocation and shows the projected outcome, efficiency and risk for each channel - explained, not generated.

Reallocate Budget (Scenario Planner)

Move budget between channels and see the projected impact across your plan.

What Forecasting Intelligence covers

Each part of Forecasting Intelligence takes you from raw campaign data to a budget recommendation you can defend.

Response curves & diminishing returns

A response curve is fitted to every channel, with adstock and saturation, so you can see where each additional pound stops paying back.

Marginal return by channel

Compare the return on the next pound, not the blended average, and see which channels still have headroom and which are past their ceiling.

Scenario modelling

Model balanced, aggressive or conservative plans across months and channels, including cross-channel interaction and seasonal effects.

Budget reallocation

Optimise across all channels at once. ElenIQ recommends where to move spend and quantifies the expected change in outcome and efficiency.

Incremental revenue forecasting

Forecast the incremental revenue and ROAS of a change for e-commerce, or leads and CPL for lead generation, with 95% prediction intervals.

Confidence and assumptions

Accuracy reported as WMAPE against your own history, a baseline comparison, and the assumptions behind every forecast shown beside it.

Explainable recommendations

Every recommendation comes with its drivers and plain-English reallocation narratives you can take into a budget review.

From input to decision

  1. 01

    Bring in campaign data

    Upload a CSV or connect a Google Sheet. ElenIQ detects channels, cost columns, currencies and date formats, then checks data quality.

  2. 02

    Set the baseline

    Set monthly budgets per channel, the KPI you plan against and the forecast horizon.

  3. 03

    Model scenarios

    Test reallocations, scale-ups and cuts, and see projected outcome, marginal return and confidence for each option.

  4. 04

    Decide and share

    Apply the scenario you back, then export the forecast and its rationale as CSV or PDF for stakeholders.

Forecasting Intelligence and Annual Investment Planning

Two capabilities, two workflows. Forecasting models proposed changes; annual planning builds the year. Forecasts can inform the returns and assumptions an annual plan uses - neither replaces the other.

Supported business models

E-commerce - Revenue & ROAS

Forecast revenue, model return on ad spend and optimise budget allocation across paid channels. ElenIQ calculates marginal efficiency curves and ROAS projections for every channel in your dataset.

Lead generation - Leads & CPL

Forecast lead volume, model cost per lead and apply lead-gen guardrails to prevent unrealistic projections, including CPL clamping, spend-range validation and conversion-rate stability checks.

Works with the rest of ElenIQ

Forecasting Intelligence sits alongside Media Planning, Annual Investment Planning, Creative Intelligence and Affiliate Growth Intelligence in the same advertiser workspace and the same subscription, with Ask Dex working across all of them. Nothing to buy separately.

Ask Dex

Ask the question. Get the reasoning.

Ask Dex works across ElenIQ. From Forecasting Intelligence it can interrogate this workspace’s outputs and the assumptions behind them, and bring in the rest of the platform when the answer needs it.

How Ask Dex works

Ask Dex · from Forecasting

“Where should we move £50k to produce the strongest incremental return?”

Based on the current response curves, Market B paid social and generic search still have headroom: their marginal return is above the portfolio average. Moving £50k from brand search - which is past its saturation point - is forecast to add incremental revenue, within a 95% range. Confidence is medium because Market B has 14 weeks of history.

  • Shows the marginal return it relied on, channel by channel
  • States the forecast range and confidence, not a single number
  • Names the assumption that would change the answer

Frequently asked questions

What is marginal ROAS?

Marginal ROAS is the return on the next pound of ad spend, not the blended average of everything spent so far. It is the additional revenue an extra increment of budget is forecast to produce divided by that increment. Forecasting Intelligence models marginal ROAS per channel so budget moves to where the next pound works hardest.

How do you forecast ad spend?

You model the relationship between spend and outcomes - accounting for diminishing returns and saturation - to project revenue, leads, ROAS or CPL before budget is committed. ElenIQ trains on your historical campaign data, fits response curves per channel, and returns confidence-scored projections with prediction intervals.

What is a saturation curve in paid media?

A saturation curve describes how extra spend on a channel returns progressively less as it scales. Early spend is efficient; beyond a point each additional pound buys fewer conversions. Forecasting Intelligence fits a saturation curve to every channel so you can see where returns start to flatten.

How do you know when a channel is saturated?

A channel is saturating when its marginal ROAS falls below its average ROAS and keeps declining as spend rises. ElenIQ flags this by comparing the next pound's forecast return against the channel's recent efficiency, so you can stop scaling before returns turn unprofitable.

How do you move budget between paid media channels?

Shift budget away from channels whose marginal return has dropped and toward channels where the next pound still performs - without starving a channel below the point it can sustain. Forecasting Intelligence recommends reallocations across all channels at once, modelling cross-channel interaction effects rather than treating each in isolation.

What data does Forecasting Intelligence need?

Historical campaign data with dates, channels, spend and an outcome column (revenue or conversions for e-commerce, leads for lead generation). Upload a CSV or connect a Google Sheet; ElenIQ auto-detects channels, cost columns, currencies and date formats, then checks data quality before forecasting.

Does it work for lead generation as well as e-commerce?

Yes. Forecasting Intelligence supports both business models: revenue and ROAS for e-commerce, and leads and CPL for lead generation. The lead-gen mode applies guardrails - CPL clamping, spend-range validation and conversion-rate stability checks - so projections stay realistic.

How accurate are the forecasts?

Every forecast reports accuracy against your own history using WMAPE as the primary metric, alongside a baseline comparison and 95% prediction intervals. ElenIQ never presents a single point estimate as certainty - it shows the expected range and a confidence score so you can judge how much to trust each projection.

How is Forecasting Intelligence different from Annual Investment Planning?

Forecasting Intelligence answers questions about scenarios and proposed changes: what happens if spend moves, where the next portion of budget should go and what the incremental return is likely to be. Annual Investment Planning is a separate workflow for the full-year budget - its market, channel and monthly allocation. Forecasts can inform the annual plan's assumptions, but the two stay distinct.
