Business Calculators

Put your business plans into numbers.

How business calculators can help.

Whether you’re preparing for self-employment taxes or considering financing for your business, a little planning can help you make more informed decisions. Use our free business calculators to estimate potential costs, compare scenarios and better understand the numbers behind your next move.

Business decisions often involve several variables. These calculators allow you to explore different scenarios before speaking with a tax professional or applying for financing.

Use them to:

  • Plan ahead for potential self-employment tax obligations
  • Estimate an affordable commercial loan payment
  • Compare different loan amounts, rates or repayment terms
  • Understand how financing costs could change over time
  • Prepare questions for a financial or tax professional

Self-Employment Tax Calculator

Estimate how much you could owe annually in self-employment taxes based on your net earnings. See projected Social Security and Medicare taxes and plan more confidently for potential tax obligations.

Commercial Loan Calculator

Estimate your monthly commercial loan payment and the total interest you could pay over the life of the loan. Adjust the loan amount, interest rate and repayment term to compare potential financing scenarios.

Understanding your results

The results are estimates based on the information you provide and the assumptions used by each calculator. They are intended for general planning purposes and do not represent tax advice, a loan offer, an approval or a guarantee of available rates or terms.

Actual tax obligations, loan payments and financing costs may vary. Consider consulting a qualified tax professional about your tax situation or speaking with a Michigan First business professional about financing options.
