What this finance path helps compare
Use this collection when you are comparing real money decisions, not just looking for a one-off formula. Start with business loan payment estimate, then move through the supporting calculators to pressure-test payment size, cash needed, breakeven timing, tax exposure, and the next best alternative.
How to use this collection
Move through the decision in order
- 1Start with the business loan or SBA calculator to translate the borrowing request into a realistic monthly payment.

- 3For acquisitions, compare business valuation, SDE vs EBITDA, and seller financing before treating the asking price as the deal value.
- 4Estimate self-employment and quarterly taxes before committing all available cash to debt payments or equipment purchases.
- 5Use QBI, S-corp, and Section 179 calculators as planning estimates, then confirm final treatment with a qualified tax professional.
