How it works
Closing balance = opening balance + each period change. Net cash flow = closing − opening.
Worked example
Opening cash of 1,000 plus changes of 500, -200, and 100 closes at 1,400; net movement is 400.
Edge cases and limitations
Inputs must be finite. Negative values are accepted only where they represent a meaningful loss or cash outflow. Rounding is display-only, and results are not tax, legal, accounting, investment, or financial advice.
Frequently asked questions
What does a negative change mean?
It represents cash leaving the business during that period, such as a payment or purchase.
