I need a dynamic loan amortization spreadsheet for a variable rate loan with the addition of an offset account and the ability of additional repayments. The goal is to forecast when the loan will be paid out based on either fortnightly or monthly repayments and the offset account balance and any additional repayments made. The spreadsheet needs to compute future repayments and loan term based on new inputs without affecting previous payments and interest calculations. The LAS spreadsheet provided in excel can be used as a reference for the layout and requirements but with the ability for various interest rates, offset account and additional repayments Core capabilities • Variable rate mortgage – I must be able to enter different interest rates for specific date ranges and see the schedule update for future without affecting the past calculations. Note interest is calculated daily by the lender • Offset facility – the balance sitting in the offset account should reduce the daily interest calculation. I want the offset amount itself to be changeable period by period so I can see the impact of moving money in or out. • Extra repayments – I need the option to enter additional, irregular payments of any size and date, with the sheet showing the shortened loan term and interest saved. • Overall summary of interest paid on the loan What I expect to see 1. An input area where I enter loan details (principal, term, start date, introductory or later rates, etc.). 2. A clear table or chart that displays the full amortisation schedule, beginning balance, ending balance, scheduled payment, extra payment, total payment, principal, interest and cumulative interest and the offset balance. 3. A summary section highlighting total interest paid, interest saved through the offset, and how much sooner the loan is paid off when I make extra repayments. Excel formulas are required. If you have suggestions for a sleeker layout or additional insights (e.g., yearly summaries, graphs), feel free to build them in. Please let me know how you plan to structure the workbook and roughly how long you’ll need; I’m ready to move ahead as soon as we agree on scope and timeline.

With my comprehensive expertise in Excel and data management, I'm ready to give you a first-rate, visually appealing solution for your variable mortgage offset calculator spreadsheet. I have worked with complex Excel functions, formulas, and pivot tables for loan and interest calculations in the past. I assure you that the spreadsheet will facilitate dynamic inputs without altering any previous calculations, enabling you to track your variable rate loan accurately. Your particular requirement of incorporating an offset account is well within my coding capabilities. I can design the sheet to show the reduction of your daily interest calculation based on changing offset amounts for each period. Moreover, my experience with handling irregular additional repayments empowers me to build an interface where you can enter those payments of any size and date precisely. For an optimized structure, I propose dividing the workbook into 3 sections for input area (loan details), full amortisation schedule (including offsets & extra payments), and summarizing tot aloutcomes (interest paid and saved). For your convenience, I can also include yearly summary visuals and graphs to provide a comprehensive overview. Let's begin now so that we can get on top of this important task together!

Your variable rate mortgage calculator needs VBA macros to handle dynamic rate changes without breaking historical calculations. I'll build a multi-sheet system with input forms, daily interest calculations incorporating offset balances, and automatic amortization updates when you change rates or add payments. I built a similar financial tracking system - my algorithmic trading bot handles complex PnL calculations with variable rates and automated risk management across multiple timeframes. You can see my other automation work at ffulb.com. Available to start immediately. This type of dynamic Excel modeling typically takes me 3-5 days to complete and test thoroughly.
