Cash Reserve Target Calculator
Decide how much cash buffer to keep.
The Open buttons send the prompt text as currently shown below to that site only when you click. Fill in the placeholders first.
Help me set a cash reserve target. Monthly fixed costs: [MONTHLY_FIXED_COSTS]. Monthly variable costs at normal sales: [MONTHLY_VARIABLE_COSTS]. How predictable my income is (very, somewhat, not): [INCOME_PREDICTABILITY]. Customer payment delays: [PAYMENT_DELAYS]. Current cash: [CURRENT_CASH]. Compute reserve targets in months of essential costs for three levels: minimum, comfortable, and resilient, using about 1 to 2, 3, and 6 months as illustrative planning ranges rather than a standard, with amounts from my numbers. Recommend a level based on my predictability and explain why. Compute the gap versus current cash and a savings plan: monthly amount needed to reach the target in 6, 12, and 24 months, showing arithmetic. Add triggers for using the reserve and for rebuilding it, a note on keeping it in an accessible account, and a review each quarter. This is general planning support, not financial advice [VERIFY with an adviser]. Include a worked example with made-up numbers labelled as an example, a monthly saving table, and a rule for what happens in a month when the saving cannot be made, such as carrying the shortfall rather than abandoning the plan.

Monthly fixed costs 6,200; variable costs at normal sales 3,800; essential monthly costs 6,200 + 3,800 x 0.5 (half the variable costs are discretionary) = 8,100. Income predictability: somewhat. Illustrative targets: minimum 2 months = 16,200; comfortable 3 months = 24,300; resilient 6 months = 48,600. Recommendation: comfortable, because invoices arrive about 25 days late. Current cash 9,500, so the gap to 24,300 is 14,800. Saving plan: 14,800 / 6 = 2,467 a month; / 12 = 1,233; / 24 = 617. Use the reserve only for a drop in income above 20 percent for two months; rebuild before new spending. Planning support, not advice.
