What this calculator does

Calculate Cash Flow step by step: Closing cash = opening cash + inflows − outflows. Worked example, questions and limitations included.

Use it to turn Currency (symbol only, never converted), Opening cash balance, Cash inflows in the period, Cash outflows in the period into a checked result you can compare, copy, or rerun with different assumptions.

The page shows the formula, a numeric worked example, and the assumptions that affect this fp&a calculation.

Inputs and what they mean

Currency (symbol only, never converted)
— choice value.
Opening cash balance
— number value.
Cash inflows in the period
— number value.
Cash outflows in the period
— number value.

How to use it

  1. Enter each value in the unit shown next to the box (use the unit converter first if your numbers are in other units).
  2. Check the breakdown to see every intermediate step.
  3. Read the limitations before relying on the result.

Formula

Cash-basis roll-forward consistent with the statement of cash flows (OpenStax Principles of Accounting Vol. 1).

Counts cash when received or paid, not when earned or incurred.

Include financing and investing flows if you want total cash movement.

Closing cash = opening cash + inflows − outflows.

Inputs used: Currency (symbol only, never converted), Opening cash balance, Cash inflows in the period, Cash outflows in the period.

Worked example

A month

  1. Net = −$15,000.
  2. 50,000 − 15,000 = $35,000.

Reading the result

The headline figure is the main answer. Any breakdown underneath shows the parts that make it up, so you can check the working and see what changes when you adjust an input.

Limitations and assumptions

  • Single period.
  • Does not split operating, investing and financing.
  • Results are educational estimates built only from the figures you enter. They are not personalised investment, tax, legal or accounting advice. Rates, growth and discount assumptions are always yours to choose.
  • The result depends on the values you enter for this cash flow calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.

Common questions

Is cash flow the same as profit?

No. Profit uses accruals; cash flow tracks actual money in and out.

Multiple months?

Run month by month, using each closing balance as the next opening. Check the formula, example, and limitations on this page before using the result for a real fp&a decision.

Is this a prediction?

No. It projects the assumptions you enter. Growth, rates and scenarios are your choices — none are built in.

How do I use the Cash Flow Calculator?

Enter the required values for Currency (symbol only, never converted), Opening cash balance, Cash inflows in the period, Cash outflows in the period. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.

What formula does the Cash Flow Calculator use?

Closing cash = opening cash + inflows − outflows. The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone.

Can the Cash Flow Calculator be used for exact decisions?

Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.
