General expenses split across units: the maths, made visible

The four rules

Equal shares — every unit the same. Simple, fair for buildings where units are alike. By floor area — bigger units carry more. Usual for mixed buildings and what most leases imply. By occupancy — only occupied units share; vacant ones bear nothing, so the cost per occupied unit rises when the building empties. Custom weights — you set a number per unit (2 for the penthouse, 0.5 for the studio) and the split follows.

Choose per place in Settings › Money › Expense split. You can also override the rule on a single expense: the elevator service split only across floors above ground, say.

Vacancy

The honest question is who pays for the corridor light outside an empty unit. Two answers, both supported. Vacant units bear their share: the P&L for an empty unit shows a cost and no income, which is exactly what vacancy costs you. Occupied units absorb it: the empty unit's P&L is flat and the others carry more. The first is more truthful; the second is what you would use to set rents that cover costs. The setting is per place.

Seeing the arithmetic

On any unit's P&L, each general line shows its share and how it was computed: "Meralco Aug ₱6,240 × 28/1,368 m² = ₱127.72". On the expense itself, a breakdown lists every unit's share. Nothing is hidden, because the day a tenant asks why their service charge went up, you want to answer in ten seconds.
