The dealership negotiates monthly. You negotiate the total.
The dealership negotiates monthly. You negotiate the total. One in five new-car buyers now pays $1,000+ a month, and the average loan runs 69.5 months. Nobody plans that — it happens one reasonable-sounding payment at a time. This 14-tab workbook makes the TOTAL the first number you see, on every tab, for every candidate car. Type the payment a dealer quoted and watch the Payment Trap price it at five terms: the same $499/month buys a $15,924 car at 36 months — or a $32,015 car at 84. The payment never moves. The months do.
- The Shortlist — 5 candidates ranked on the 5-YEAR total, not the sticker
- Out-the-Door Decoder — taxes, title, doc fee, and an add-on table defaulting every extra to No
- The Payment Trap — same payment five ways + the negative-equity calculator
- Loan vs Lease — the money factor translated into an APR you can compare
- Loan Interest Deduction — the 2025–2028 rules computed at YOUR income
Overview
The dealership negotiates monthly. You negotiate the total.
One in five new-car buyers now pays $1,000+ a month, and the average loan runs 69.5 months. Nobody plans that — it happens one reasonable-sounding payment at a time. This 14-tab workbook makes the TOTAL the first number you see, on every tab, for every candidate car. Type the payment a dealer quoted and watch the Payment Trap price it at five terms: the same $499/month buys a $15,924 car at 36 months — or a $32,015 car at 84. The payment never moves. The months do.
That is the trick, and this file un-tricks it.

Key Benefits
Why this one
Every tab leads with the out-the-door and 5-year totals — the two numbers the dealership never volunteers.
$499/month is a $15,924 car at 36 months or a $32,015 car at 84. Five terms side by side, every time.
Your Money computes the per-paycheck ceiling before any test drive — and the readiness check is allowed to say no.
Loan Lab runs the full amortization plus an Offer B lane so your pre-approval can fight the dealer's sheet.
Car loan interest 2025–2028: new, US-assembled, with the real phaseout — computed at your income, not the headline.
1,283 formulas · recalculated clean · 496/496 independent math checks. Every image is the real file.
Who It's For
Built for
- Anyone about to walk into a dealership armed with only a monthly budget
- First-time buyers who want the readiness check before the test drive
- Households comparing loan vs lease with real numbers
- Trade-in owners who suspect the payment hides the deal
How It Works
Up and running in minutes
The ACCESS-YOUR-TEMPLATE.pdf in your download opens a copy in Google Sheets with one click
Your Money turns your paycheck into a per-paycheck comfort slice before the lot visit
Five candidates, ranked on the five-year total — the used car often wins the war
Out-the-door line by line; every add-on defaults to No until you say otherwise
The dashboard's readiness check passes or fails the deal — and is allowed to say no
Why It's Different
Not another template
Car budgeting templates compare monthly payments — exactly the number the dealership wants you looking at. This file refuses: totals first, five terms side by side, money factor translated, negative equity computed, and a readiness check that can fail a deal you wanted to pass.
Delivery & Compatibility
Instant, and works with what you use
As soon as your order is complete you get instant access to download your files. Prefer Google Sheets for real-time updates and dropdowns? It's fully optimized. More comfortable in Excel? It works just as well.
Built and tested in the latest Excel (Office 365). On Mac we recommend the Google Sheets version — the template is not compatible with Apple Numbers. Available in English. The template ships with sample data so every screen works on open; clear it whenever you're ready. The images and video show that sample data to demonstrate how it looks in use.
FAQ
Questions, answered
Does it work in Google Sheets?
Yes — one click: the ACCESS-YOUR-TEMPLATE.pdf in your download opens a copy straight into Google Sheets. The .xlsx works in Excel too.
Will it work for used cars?
Yes — candidates can be new or used; the five-year ranking and out-the-door decoder work the same. In the sample, a used car wins.
Does it handle a trade-in?
Yes — three offers side by side, with the trade-in tax credit included where your state allows it.
What about the new car-loan interest deduction?
Computed at your income with the real 2025–2028 rules — new vehicles, US-assembled, with the phaseout cliff shown in dollars.
Is anything pre-loaded?
Sample data (Maya's five-candidate hunt) ships inside so every screen works on open — clear it when you're ready.
Can I get a refund on a digital download?
