Weekly closing cash = weekly opening cash + dated receipts − dated obligations − proposed order payment
The next week starts with the previous week’s closing cash. Week 1 begins the day after the reconciled opening cash date. The proposed order is one cash payment in the selected week. The before-order comparison omits that payment.
The lowest balance is the minimum of the opening cash and every weekly closing balance. Buffer headroom or shortfall equals that lowest balance minus your minimum buffer. The buffer is a comparison threshold, so it is not deducted as an expense.
Every receipt arrives and every obligation is paid on its entered date and for its entered amount. Only entered movements are included. Use one currency, CAD, and include each payment once. Opening cash already includes movements through its as of date.
Weekly closes can conceal a shortage within a week. Check daily timing before making a commitment. Delayed collections, unentered bills, changing costs and payment terms can change the outcome. A positive buffer does not prove that an order is affordable or that funds are available today.
This is a planning comparison, not a guarantee, purchasing authorization, lender assessment or accounting or tax advice. Amounts use exact cents. Missing, negative, nonfinite, out-of-range or overly precise inputs withhold the result.
Method context: BDC’s cash flow planning explanation describes comparing expected cash inflows and outflows over a weekly or monthly horizon. This calculator’s order comparison and reserve are explicit user assumptions.
