Revenue minus a lump of operating expenses you chose to sum for a planning pass.
Overview
Plain subtraction for founder snapshots—not tax, interest, or depreciation precision unless you fold them into the expense blob with intent.
When to use this calculator
- When you need blunt revenue minus a lump-sum expense blob
- Before you call it audited net income—the nuance stays with finance
- When owner draws and tax timing refuse to behave monthly
- When seasonality swings one-month reads
Rule of thumb
Lump-sum expenses hide tax timing, capex quirks, draws—finance still owns audited truth.
