How to measure return from estate agent prospecting

By ProspectOS Editorial Team|Published 14 August 2026|Last reviewed 14 August 2026

To measure return from estate agent prospecting, use a defined reporting scope, complete recorded costs and confirmed agency fee revenue linked through an agreed attribution model. Keep return multiple, net ROI percentage and break even separate so the branch knows what each figure means.

Key points
Define the campaign, postcode, branch and period being measured.
Use agency fee revenue, not property sale price or annual rent.
Include every cost that belongs in the selected scope.
Keep return multiple and net ROI percentage distinct.
Treat attribution as recorded contribution, not proof of exclusive causation.

Define the reporting scope

Start by stating whether the review covers one campaign, one postcode, one market type or the whole branch. Set the start and end dates and decide which cost components belong in the view.

Do not compare a narrow campaign cost with revenue from a wider branch period. The scope of the numerator and denominator must agree.

Total cost

Total cost is the sum of all costs included in the reporting scope. It may include letters or postcards, a selected campaign package, Land Registry or data checks and other explicit campaign costs.

Include fixed subscription allocation only when the view is clearly labelled as fully loaded and the allocation policy is approved. Preserve the send time or purchase cost rather than silently replacing it with today's price.

Attributed revenue

Attributed revenue is confirmed agency fee revenue connected to an instruction through the approved attribution model. It is not the property's sale price, asking price, annual rent or deposit.

A possible detected instruction should contribute no won revenue until an authorised person confirms the outcome.

Return multiple

Return multiple equals attributed revenue divided by total cost.

Illustrative example: attributed fee revenue of £3,000 divided by recorded cost of £1,000 gives a return multiple of 3.

Net ROI percentage

Net ROI percentage equals attributed revenue minus total cost, divided by total cost, multiplied by 100.

Using the same illustrative figures, the net return is £2,000 and the net ROI is 200 per cent.

The return multiple and net ROI describe the same inputs in different ways. A return multiple of 3 is not the same as 300 per cent net ROI.

Break even

Break even revenue is the attributed fee revenue required to equal total cost. If recorded cost is £1,000, the campaign reaches break even at £1,000 of attributed fee revenue.

When total cost is zero, do not display an infinite return. Mark the measure as unavailable because no cost was recorded.

Attribution and causation

An instruction may be influenced by local reputation, previous contact, portal activity, staff relationships and several campaigns. Attribution applies a consistent rule to connect the confirmed outcome with recorded sources.

That connection supports contribution reporting. It does not prove that one letter or one campaign caused the instruction alone. Prevent the same instruction from being counted more than once across contributing sources.

A practical branch workflow

  1. 1Define scope, market type and period.
  2. 2Reconcile sends and other recorded costs.
  3. 3Confirm won instructions and agency fee revenue.
  4. 4Apply the attribution model once per outcome.
  5. 5Calculate return multiple, net return, net ROI and break even.
  6. 6Flag missing or incomplete data.
  7. 7Review the result alongside activity and follow up quality.

Common mistakes

  • Using property value as agency revenue.
  • Excluding package or data costs without explanation.
  • Calling return multiple ROI percentage.
  • Counting possible instructions as won.
  • Counting one instruction against several campaigns.
  • Presenting a forecast as an achieved result.
  • Treating attribution as proof of causation.

Measurement and review

Reconcile campaign totals with postcode and branch views. Make sure visible reports and exports use the same cost snapshot, outcome status and formula. Review data completeness before drawing a commercial conclusion.

Forecasts should remain separate from actuals and show their volume, conversion, fee and cost assumptions. They are models, not guarantees.
