Loan Calculator for Dentists: Monthly Payment, Interest & Affordability
Before you sign a practice acquisition, fit-out, or equipment loan, run the numbers once — properly. Our free loan calculator shows your monthly payment, total interest, payoff timeline with extra payments, and a simple affordability check based on your practice collections.
TL;DR
- Keep total debt service around 15–20% of gross monthly collections.
- Extra payments early (even $500/month) can save tens of thousands.
- Fees compound: rolled-in origination fees increase both principal and interest.
What this loan calculator helps you decide
Generic calculators usually stop at a monthly payment. For dentists, the more useful questions are: what is the true lifetime cost, how do fees change the deal, and can your collections comfortably service the debt while you still pay staff, lab bills, rent, and yourself?
- Monthly payment (standard amortisation)
- Total interest + total repaid across the term
- Loan + fees so you can compare lenders correctly
- Extra payment impact (time saved + interest saved)
- Affordability vs gross monthly collections (15–20% guideline)
Worked example (to sanity-check a lender quote)
Example
Loan: $400,000 | APR: 7.5% | Term: 10 years
- Monthly payment: $4,744
- Total interest: $169,280
- Total repaid: $569,280
Get the inputs right (4 numbers that change everything)
Loan amount
Use the amount your collections can support — not the maximum approval. If the payment forces you above the 20% debt-service guideline, it's usually a term/price/loan-size problem.
APR (interest rate)
Enter APR (Annual Percentage Rate) to compare lenders on a like-for-like basis.
Term
Longer terms reduce monthly payments but increase total interest. Use the calculator to find the shortest term your cash flow can carry.
Fees
Ask for the full fee schedule (origination, valuation, legal, closing). If fees are rolled into the loan, they compound for years.
Affordability (15–20% rule)
A widely used benchmark in practice finance is keeping total debt service around 15–20% of gross monthly collections. If your payment is $5,000/month, the practice typically needs roughly $25,000–$33,000/month in collections to remain comfortable.
