This method is useful for startups with no revenue or for companies who want to invest a fixed amount in an experimental project.
The reserves method is simple. You look at your total Free Cash and divide it by the number of periods you need the funds to cover. The result is your budget for the period.
Free Cash = Total Cash in Bank - Current Liabilities - Other Cash Outflows.
Note: for pre-revenue companies who are using this method to determine the budget for an experimental project, the formula for Free Cash is reduced by the operational expenses required to operate the business until it is profitable or until additional funding is made available.
Operating Budget Example:
Unicorn LLC. has the following balance sheet composition:
Cash in Bank: $100,000
Accounts Payable: $5,000
Credit Card Balance: $3,500
Unicorn LLC has no revenue coming in the door and needs to last another 6 months to buy itself time until the next funding round. The company also anticipates an upcoming tax bill of appx. $5,000
Free Cash = $86,500
6 Month Budget = $86,500
Project Budget = $86,500 - (6 x 12,000) =
Avg. Monthly Budget = $14,400/mo
Action Plan
The company needs to ensure its operating expenses to fit into a budget of $14,400/month in order to last 6 months.
Project Budget Example
Unicorn LLC has same scenario as above and the company spends $12,000/mo on average and forecasts the same to be true for the next 6 months. It wants to invest in a marketing campaign to improve its customer growth numbers so it has an easier time impressing investors.
Total Project Budget
$86,500 - (6 x 12,000) = $14,500
Avg. Monthly Marketing Budget
$14,500 / 6 months = $2,416/mo
Action Plan
Unicorn LLC has enough cash to last for 6 months and invest $14,500 in a marketing campaign provided it does not exceed $12,000/mo in operating expenses.
