Amortization Schedule Calculator
A mortgage-only amortization schedule (principal + interest + mortgage insurance if applicable). Taxes and homeowners insurance are intentionally excluded.
How to Use This
Enter purchase price, down payment, and interest rate to generate a month-by-month amortization schedule. Use the controls to view shorter windows or the full term to understand how your loan balance declines over time.
Planning Tips
Mortgage loans are front-loaded with interest. Early years build equity more slowly than many buyers expect. Reviewing the full amortization schedule helps clarify how refinancing, extra principal payments, or term selection affect long-term ownership value.
Report Information
Loan Inputs
- We use a conservative, minimum average annual rate by area (Queens/Other 3%, Nassau 5%, Suffolk 4%).
- Monthly “Market Appreciation” is calculated as (Purchase Price × Annual Rate ÷ 12) and then accumulated.
- Total Equity Appreciation = Total Principal Paid + cumulative Market Appreciation.
Mortgage Insurance (PMI / FHA MIP) — How this tool estimates it
- Conventional PMI (estimate): monthly PMI is calculated on the original loan amount (base principal) as (Loan Amount × 0.30% ÷ 12). PMI remains flat until it ends.
- PMI end rule: this tool ends PMI at 78% LTV (auto-cancel). Many borrowers can request cancellation at 80% LTV—we show the conservative 78% rule in the math.
- FHA: 1.75% upfront fee (assumed financed) plus monthly MIP based on the current outstanding balance: (Balance × 0.55% ÷ 12).
- FHA duration (simplified): if down payment is < 10%, MIP is modeled for the full term; if ≥ 10%, MIP is modeled for 11 years (or until payoff if sooner).
- Removal strategy note: refinancing to conventional is typically the way to eliminate FHA MIP once you have sufficient equity.
- Rate note: FHA effective rate is modeled as (entered rate − 0.20%) for comparison consistency across your calculators.

How to Interpret This Estimate
This amortization schedule shows how each monthly payment is divided between principal reduction, interest expense, and mortgage insurance (if applicable), and how your balance declines over time.
- Early payments are interest-heavy: principal reduction accelerates later in the term.
- Equity builds gradually at first: then compounds as balance declines and appreciation accumulates.
- LTV milestones matter: crossing 80%, 75%, or 50% loan-to-value can affect refinancing flexibility and risk profile.
The chart visualizes long-term ownership behavior — not just monthly cost.
Next Step: Refine Your Strategy
Understanding how your loan amortizes helps you make smarter decisions about refinancing, term selection, prepayment strategy, and long-term wealth positioning.
Strategic homeowners evaluate not only payment size, but how capital is allocated over time and how market appreciation interacts with debt reduction.
