Quick answer

What does the Seasonal cash gap calculate?

How low does cash fall when busy months are followed by quiet ones? This calculator uses cash at the start, busy months, receipts in a busy month, receipts in a quiet month, and spending every month to estimate lowest cash in the year immediately in your browser.

With the values currently entered, the result is -$21,000.00 — short at the low point. It also shows ending cash, months spending exceeds receipts, quiet-month gap, and cash after the busy months.

How to use the Seasonal cash gap

  1. Replace the example values with your own numbers.
  2. Review the result and supporting figures as they update automatically.
  3. Check the formula and assumptions before using the estimate for a decision.

Inputs used

  • Cash at the start
  • Busy months — entered in months
  • Receipts in a busy month
  • Receipts in a quiet month
  • Spending every month

Seasonal cash gap formula

For 12 months, busy months come first. Each month adds receipts and subtracts spending. The gap is the lowest cash on that path.

Assumptions

  • SBA describes a cash-flow projection as money in and money out. The cash method records a sale when the payment arrives. This page uses the receipts and spending you type.
  • Busy months come first, then quiet months. A tax bill, a stock-up, or a busy season later in the year can move the trough.

Practical guide

Seasonal cash gap example and edge cases

A seasonal year can show a profit and still run out of cash. SBA asks you to project cash flow from money in and money out. This page walks twelve months. Busy months come first. Quiet months follow. Cash moves by that month’s receipts minus spending.

Example: Three busy months, then nine quiet ones

You start with 12,000. Three busy months bring 18,000 each. The other nine bring 5,000. Spending stays 11,000 every month.

Calculated result-$21,000.00short at the low point

Cash reaches 33,000 after the busy months, then falls. The low point is 21,000 short. Nine months spend more than they collect. Ending cash is also 21,000 short.

How to read the result

  • Read the lowest cash first. A negative number is the extra cash this calendar needs before the year starts, if the pattern holds.
  • The short-month count is how long spending outruns receipts. The quiet-month gap is one of those months on its own, here 6,000.

Edge cases worth checking

The busy season is not at the start

This page puts busy months first. If the slow season comes first, the trough arrives sooner and the opening cash has to cover it. Raise the starting cash and read the low point again.

A tax bill lands in one quiet month

Spending is flat here. A quarterly tax payment or a stock-up belongs in the heavy month. Raise monthly spending if you want the trough that bill would create.

What changes the result most

Cash at the start

Use a current amount for cash at the start. Include fees or recurring costs that belong in the same figure.

Busy months

Keep busy months on the same time basis as the other inputs. Monthly and annual values are easy to mix up.

Receipts in a busy month

Use a current amount for receipts in a busy month. Include fees or recurring costs that belong in the same figure.

Common mistakes

Check cash at the start

SBA describes a cash-flow projection as money in and money out. The cash method records a sale when the payment arrives. This page uses the receipts and spending you type. Make sure this matches the number you enter.

Keep spending every month consistent

Busy months come first, then quiet months. A tax bill, a stock-up, or a busy season later in the year can move the trough. Use the same units and time period throughout the calculation.

Do not rely on one seasonal cash gap scenario

Run a cautious case and an optimistic case. The range is often more useful than one exact-looking number.
