Estimates obtained from the credit and collection department are as follows: collections within the month of sale, 20%; collections during the month following the sale, 60%; collections the second month following the sale, 25%. Payments for labor and raw materials are typically made during the month following the one in which these costs were incurred. Total costs for labor and raw materials are estimated for each month as shown in the table. General and administrative salaries will amount to approximately $25,000 a month; lease payments under long-term lease contracts will be $7,000 a month; depreciation charges will be $8,000 a month; miscellaneous expenses will be $5,000 a month; income tax payments of $30,000 will be due in both August and December; and a progress payment of $95,000 on a new office suite must be paid in October. Cash on hand on July 1 will amount to $70,000, and a minimum cash balance of $30,000 will be maintained throughout the cash budget period.
