Understand what the model assumes
The loan model uses equal monthly payments in arrears, a nominal annual note rate divided by 12, and a balance measured just after the scheduled maturity payment. A 0% note rate and an all-cash purchase are supported. The note rate excludes fees and is not APR.
Routine-service allowances exclude the individually listed maintenance events. Event reserve funding sets cash aside; it is separate from operating expenses. A due-now event gap appears separately so it does not disappear into a monthly average.
This file does not determine airworthiness, taxes, aircraft value, lender eligibility, variable-rate resets or credit approval. Confirm costs, maintenance timing, structure, recourse, prepayment and covenants with the appropriate professionals. Jaken Aviation is a financing brokerage. Jaken fees are due at closing; nothing is charged upfront. Third-party expenses follow their own terms.

Workbook questions
What is included in the aircraft purchase workbook?
One Excel workbook with nine tabs and a PDF quick-start guide. The model compares three financing offers, reconciles cash at closing, builds an annual ownership budget, plans maintenance reserves and tests a stress case.
How do I download the workbook?
Submit your email on this page. After Netlify records and verifies the request, a download page opens and starts the Excel download. No inbox verification is required. You can also download the PDF guide during the same 24-hour browser session.
Do I need to provide a phone number or financial documents?
No. Only email is required. Aircraft category and purchase timeline are optional. Do not submit tax returns, account numbers, financial statements or other sensitive documents through this resource form.
Are the example rates and costs current financing terms?
No. Every prefilled financial example is fictional and editable. It is not a market rate, a financing offer, an aircraft valuation or a lender decision. Replace the example with estimates and written terms relevant to your purchase.
Will my workbook inputs be uploaded to Jaken Aviation?
No. This downloadable workbook has no macros, external data connections or upload feature. Financial modeling stays in your saved workbook. The website stores the contact and interest details submitted through the resource form.
Can I use the workbook for a turboprop or jet purchase?
The editable cash, fixed-payment loan, budget and reserve calculations can support planning across aircraft categories. Complex jet structures, variable-rate loans, multiple-aircraft transactions, tax treatment, maintenance programs and lender covenants need separate professional review.
Does downloading the workbook apply for financing?
No. Requesting a resource is separate from a financing inquiry, underwriting or approval. If you want to discuss a purchase, you can choose the separate financing inquiry after downloading.
Are there any upfront Jaken fees?
Jaken fees are due at closing; nothing is charged upfront. Third-party expenses follow their own terms. The workbook is free to request.
