Generate a full payment-by-payment amortization table for any business loan amount, rate, and term. See exactly how each payment splits between principal and interest.
Frequently Asked Questions
What is an amortization schedule?
A payment-by-payment table showing how each installment splits between principal and interest, plus the remaining balance after each payment. Early payments are interest-heavy; later payments shift to principal.
How is each payment split?
Each period: interest = remaining balance × periodic rate. The rest reduces principal. As the balance falls, interest share shrinks and principal share grows — even though the payment stays the same.
What's the difference between monthly and biweekly schedules?
Biweekly schedules make 26 half-payments per year (equivalent to 13 monthly payments), cutting months off the term and reducing total interest on long loans.
Does the schedule include fees?
It shows principal and interest only. Origination fees, closing costs, and servicing fees are not amortized into the table — add them separately.
Can I use this for an SBA loan?
Yes — SBA 7(a) and 504 loans amortize like standard term loans. Use your specific rate and term. Variable-rate SBA loans reset periodically, so the schedule is an estimate.
What if my loan has a balloon payment?
This generator models a fully amortizing loan. For balloon structures, amortize on the implied term and add the balloon as a final payment outside the table.
How does extra payment affect the schedule?
Extra principal reduces the balance immediately, lowering future interest and shortening the term. Even small extra payments early in the schedule save significant interest.
Is the interest in this table tax deductible?
Interest on a legitimate business loan is generally tax deductible as a business expense. The schedule helps you identify the interest portion of each payment for accounting.
Why does the last payment sometimes differ?
Rounding to the cent across many periods creates tiny differences. The final payment is adjusted to bring the balance to exactly zero.
