They sit next to each other but answer different questions: Balloon Loan Calculator is the one to open when you need it to works out the instalment and the balloon lump sum for a loan amortised over one term but repaid in full after a shorter one. The balloon is the true remaining principal after k payments, not the amount borrowed minus the payments made — the two differ by tens of thousands. Interest-only balloons are handled too, with the full schedule. Pick whichever matches what you're starting from — both are free.

Car Loan Payoff Calculator is the closest one after this: How long to pay off your car loan, total interest and payoff date — plus the effect of an extra payment.

Loan Comparison Calculator and Student Loan Payoff Calculator — they come up in the same task often enough to be worth a second tab.
