Equity IRR calculator

Calculate the time-weighted internal rate of return on the equity invested in a development project — what capital partners care about most.

Run it in FeasoSee worked example

Formula

Equity IRR = discount rate that sets NPV of equity cashflows to zero

Equity cashflows = equity contributions (negative) plus equity distributions (positive), period by period.

Inputs

Equity drawdown schedule
Equity contributions, period by period — usually heaviest in months 1–6 (acquisition, deposits, early works).
Equity distribution schedule
Equity returns, period by period — usually concentrated around settlement of completed dwellings.

Output

Equity IRR (%)
Annualised time-weighted return on equity. Capital partners typically look for 20%+ on build-to-sell apartments.

Worked example

$5M of equity drawn evenly over months 1–6, $7.1M returned over months 30–34: equity IRR ≈ 18.4%.

If the same $2.1M equity profit returned in 18 months instead of 34, IRR climbs above 25%. Time matters.
