FTE difference vs current0.00 FTE

FTE requirement is based on your KPI and fixed target revenue per FTE.

Formula: FTE Required = Recognised Revenue KPI ÷ Target Average Revenue per FTE. Use matching periods (for example, monthly revenue and monthly revenue per FTE). This is a total-company FTE equivalent, not an installer-only headcount.

Option B · Company-wide revenue target, installer-only output

Recognised Revenue KPI ($) Total revenue target for the period.

Actual Recognised Revenue ($) Actual revenue recognised for the same period.

Target Average Revenue per FTE ($) Target based on all company FTE, including installers and office staff.

Office & Non-Installation FTE Assumed to remain constant.

Current Installer FTE Current installer FTE to compare against the requirement.

INSTALLERS REQUIRED

5.00 FTE

Total company FTE required 8.00 FTE

Additional installers needed 0.00 FTE

Revenue KPI achieved 87.5%

Revenue remaining $50,000

Current total company FTE 8.00 FTE

Installer requirements are calculated using the revenue target per FTE.

Formula: Total company FTE required = Revenue KPI ÷ Target Average Revenue per FTE. Installers required = total company FTE required − office/non-installation FTE. Additional installers needed = the greater of zero or installers required − current installer FTE.

Important assumption: This calculation assumes the revenue target per FTE is appropriate for the whole company and holds office/non-installation FTE constant. Validate the result against actual installation capacity.

Forecast installer capacity using historical recognised revenue. Office and support staff are included in company-wide productivity.

Recognised Revenue KPI ($) Revenue target for the forecast period.

Actual Recognised Revenue ($) Historical revenue for the productivity calculation.

Historical Installer FTE Average installer FTE during the historical period.

Current Installer FTE Current available installer workforce.

Office & Support FTE Include sales, scheduling, management and other non-installation staff.

INSTALLERS REQUIRED

6 installers

Historical revenue per installer FTE $70,000

Additional installers needed 1.00 FTE

Total company FTE required 9.00 FTE

Current total company FTE 8.00 FTE

Company-wide revenue per FTE (historical) $43,750

Revenue KPI achieved 87.5%

Revenue remaining to KPI $50,000

Installer requirements are based on historical recognised revenue per installer FTE.

Formulas: Revenue per installer FTE = historical actual recognised revenue ÷ historical installer FTE. Installers required = KPI ÷ revenue per installer FTE, rounded up to a whole installer. Company-wide revenue per FTE = historical revenue ÷ current total company FTE.

Use the same period for historical revenue and installer FTE. This forecast assumes historical productivity is a reasonable guide to future capacity. Seasonality, job mix, downtime and installation complexity can affect results.
