Loan calculation questions
What is an amortizing loan?
Each equal payment includes principal and interest. Interest makes up more of early payments, while principal becomes a larger share later.
Can I use this for an adjustable-rate loan?
The result assumes today's rate remains fixed. Recalculate with the remaining balance and term whenever the rate changes.
Does a 0% rate work?
Yes. At 0%, the principal is divided evenly by the number of monthly payments.
