Amortization front-loads the interest
An estimate, not tax or lending advice
This calculator provides a simplified estimate for planning purposes only. Your lender's figures are authoritative for your loan. For questions about the tax treatment of interest, talk with Alumbra CPA.
- Every payment is the same size, but the split changes. Interest is charged on the outstanding balance, so as the balance falls, more of each payment goes to principal.
- Extra principal payments compound in your favor. Each dollar of extra principal removes all the future interest that dollar would have accrued.
- Mortgage interest may be deductible if you itemize, subject to limits on the amount of qualifying debt. Interest on business or rental property loans follows different rules.
- Business loan interest is generally deductible as a business expense, which can change the after-tax cost of borrowing meaningfully.
- Not included here: property taxes, insurance, PMI, HOA dues, escrow, closing costs, points, prepayment penalties, and variable-rate adjustments.
- This assumes a fixed rate with monthly compounding and payments applied on schedule. Confirm the details with your lender.
The after-tax cost of a loan is often what matters most
Whether you are financing a property, equipment, or a business acquisition, we can help you look at deductibility, structure, and timing alongside the payment itself.
