How this calculator works
Estimate monthly payment, extra payment payoff speed, interest saved, and loan fees.
Example
Extra monthly payments can shorten the payoff schedule and reduce interest, but origination fees still affect total borrowing cost.
What makes this tool more practical
- The extra payment field estimates how faster principal reduction affects payoff time and total interest.
- Origination fee is shown separately because it may not appear in the monthly payment but still increases total borrowing cost.
- Use the result as a cash-flow planning estimate before comparing lender quotes and repayment terms.
When to use it
Use this tool when you need a quick business estimate before setting a price, sending a quote, planning a campaign, comparing fees, or checking whether the numbers still make sense.
Important note
Results are estimates based on the numbers you enter. They do not replace professional accounting, tax, legal, lending, or financial advice.
