Why combine your loans into one view?
Most people carry more than one loan at a time — a mortgage, a car payment, student loans — each amortizing on its own schedule. This calculator adds them together so you can see your real combined monthly obligation today, how that total shrinks as each loan finishes its term, and when you'll be completely loan-free across everything at once.
How each loan is calculated
Every loan is amortized independently using the standard formula, on its own balance, rate, and term:
The combined monthly payment shown is simply the sum of every loan still active that month — as loans finish, they drop out and your combined payment steps down. Need to model one loan on its own in more detail, with extra payments? Use the single loan calculator instead.

Frequently asked questions
This tool amortizes each loan on its own fixed term, like a mortgage or auto loan, and adds up the results.

Not in this calculator — each loan runs its own independent schedule. Once a loan's term ends, it simply drops out of the combined monthly payment and total balance automatically.
Yes — any fixed-rate, fixed-term loan works the same way mathematically. Add each one with its own balance, rate, and remaining term.
