Scope: Market-neutral small-business planning using your own assumptions.
Owners stress-testing whether operating cash can cover scheduled debt and lease obligations.
Total debt service, base and downside coverage, cash gap to the selected threshold and downside status.
Use one period for cash and debt payments, then choose a conservative cash-reduction scenario.
Use a different tool when: Do not use this to compare periodic loan repayments and total interest across financing terms; use Business Loan Repayment Planner for that decision. Use this tool to stress-test operating cash coverage of scheduled debt obligations.
