An AAACU loan calculator is a web-based tool that estimates monthly payments, total interest, and loan payoff schedules for loans offered by AAACU (or any lender) using the principal amount, APR, term length, and optional extra payments.
How to Use the AAACU Loan Calculator — Step-by-Step Guide
What this calculator does
This calculator helps borrowers estimate monthly payments, total interest, and the amortization schedule for a loan. It computes the standard amortizing monthly payment (using APR converted to a monthly rate), allows you to add optional extra monthly payments to model accelerated payoff, and displays interactive visualizations (an amortization balance chart and monthly payment breakdown) using Plotly.js. It is sized to fit a typical WordPress content column (responsive, max-width 720px), has a white background for clean visual integration between sidebars, and is delivered as a single HTML file you can paste into a WordPress Custom HTML block.
Inputs explained
- Loan amount (Principal) — Enter the total amount you plan to borrow. The calculator uses this to compute payments and interest.
- Interest rate (APR %) — Enter the annual percentage rate as a percent (e.g., 7.5). The calculator converts APR to a monthly rate for calculations.
- Term (years) — Select the loan term in years. The calculator converts years into months to calculate the monthly payment and schedule.
- Extra monthly payment — Optional. If you add an extra amount to each monthly payment, the calculator will show how much sooner you’ll pay off the loan and how much interest you’ll save.
- Start month — Optionally choose the month you expect the first payment to appear; this helps the table and charts show calendar dates for each payment.
Outputs and visuals
After entering values and clicking Calculate, you’ll see:
- Estimated monthly payment — the base payment plus any extra payment you entered (displayed clearly).
- Total interest paid — the sum of all interest across the amortization schedule.
- Total loan cost — principal + total interest.
- Remaining balance chart — interactive line chart showing the loan balance falling over time.
- Payment breakdown chart — stacked area chart showing how each monthly payment is split between principal and interest over time.
- Amortization preview table — the first 12 payment rows are shown in a scrollable table for quick review (full schedule is derived in the background for the charts).
How the math works (brief)
The calculator uses the standard fixed-rate amortization formula:
Monthly payment = (P * r) / (1 − (1 + r)^−N)
where P = principal, r = monthly interest rate (APR / 12 / 100), and N = number of months. If extra monthly payments are provided, the extra reduces principal faster, accelerating payoff and lowering total interest.
Embedding in WordPress (practical steps)
- Open your page/post editor and add a Custom HTML block (or use your theme’s code area if supported).
- Copy the entire HTML file from the tool I created and paste it into the Custom HTML block. The single-file structure includes CSS, the Plotly.js script reference (CDN), HTML layout, and the JavaScript calculation logic — no other files required.
- Save and preview. The container is responsive and uses
max-width: 720pxso it will comfortably fit most WordPress content areas located between left and right sidebars. If your theme’s content column is narrower or wider, the tool will adapt (it useswidth: 100%up to the max width). - If your WordPress host or security plugin blocks inline scripts from the editor, paste the HTML into a template file or use a plugin that permits custom HTML with scripts (e.g., a code snippet plugin or a child theme template).
Design & accessibility notes
- The calculator uses a white background and subtle shadows to blend with most site designs.
- Inputs are large and labeled for clarity; results are in visually distinct cards so users can quickly scan totals.
- Charts are interactive (Plotly) and responsive; they include hover tooltips for precise values.
Why include extra payments?
Making extra monthly payments directly reduces outstanding principal. This reduces future interest charges and shortens the loan term — the tool quantifies both the interest saved and the earlier payoff date by recalculating the amortization schedule when extras are added.
Troubleshooting & tips
- If the chart or scripts don’t load, ensure your site allows external script loading and that the Plotly CDN isn’t blocked.
- If your content column is narrower than 720px, the tool will scale down; no action required. If you want a different max width, you can edit the
max-widthproperty in the embedded CSS. - For lenders requiring daily interest accrual or simple interest calculations, this fixed-rate amortization model may not match exact contractual accruals; consult loan documents for exact payoff amounts.
Disclaimer

Always confirm exact payment schedules, interest calculations, and payoff amounts with your lender before making financial decisions.
FAQ
Q: Is this tool specific to AAACU rates or accounts?
A: No — the calculator models standard fixed-rate amortizing loans. You can enter any principal and APR to model loans. Use AAACU-specific rates to estimate AAACU loan results.
Q: Can I export the amortization schedule?
A: The embedded tool shows the first 12 rows and powers the charts from the full schedule. You can extend the code to export CSV or a printable table — if you want, I can add a CSV export button.
Q: Will this work in any WordPress theme?
A: Yes, as long as the theme allows custom HTML blocks with inline JavaScript and external script loading. If your host removes inline scripts, use a child theme template or a plugin that lets you add custom code safely.
Q: Does the calculator consider fees or balloon payments?
A: The current version does not include origination fees, upfront charges, or balloon payments. If you need those features, I can modify the code to include fees or a balloon/balloon payoff input.
Q: Is Plotly required? Can I swap charts?
A: Plotly provides interactive charts and is loaded via CDN in the single-file tool. If you prefer another charting library (Chart.js, D3), the UI can be adapted — let me know which one and I’ll provide an alternate version.
