DentiPath Tools
Dental loan repayment calculator
Estimate the payment, total interest, and total cash on a student, practice, or equipment loan. Switch between amortized and interest-only, and between monthly, biweekly, and weekly payments. Everything runs in your browser.
Enter decimals with a period. Commas can separate thousands.
How the estimate works
A fixed-rate loan payment depends on three things: the amount borrowed, the periodic interest rate, and the number of payments. The calculator divides your annual rate evenly across the periods in a year (12 monthly, 26 biweekly, 52 weekly), then solves for the level payment that clears the balance over the term.
Take the default: $350,000 at 6.5% over 10 years, paid monthly. That is about $3,975 a month, roughly $477,000 repaid in total, of which about $127,000 is interest. Switch to interest-only and the monthly payment drops, but none of the principal is repaid, so the full $350,000 is still owed at the end. The total interest you pay is the real cost of the loan, and it grows with the rate and the term.

Questions
Does this calculator send my numbers anywhere?
In the current version, calculations run locally in your browser. Values entered in this calculator are not transmitted to DentiPath, saved to an account, or used for advertising tracking.
What is the difference between amortized and interest-only?
An amortized loan pays interest plus a little principal each period, so the balance reaches zero by the end of the term. An interest-only loan pays just the interest, so the full principal is still owed at the end.
Does the rate include compounding?
The estimate divides the annual rate evenly across the payment periods, the common approximation for fixed-rate loans. Your lender’s exact method, fees, and compounding can change the real figures, so confirm with your lender.
