# FSD subscription vs purchase calculator

https://cushly.eu/tools/fsd-subscription-vs-purchase/ · Updated 24 September 2026

Enter a monthly price, a one-off price and how many months you keep the car. All three defaults are round examples.

## Inputs

- `monthly`: Subscription price per month (number, default 100 €)
- `purchase`: One-off purchase price (number, default 8000 €)
- `months`: Months you keep the car (number, default 48)

## Result (defaults)

After 48 months the subscription costs €4,800.00, €3,200.00 less than buying.
- Subscription total: €4,800.00
- One-off price: €8,000.00
- Subscription cheaper by: €3,200.00
- Break-even month: Month 80

## How it works

Subscription total = monthly price × months you keep the car. Break-even month = one-off price ÷ monthly price, rounded up. Before that month the subscription has cost less in total, after it buying would have cost less.

## Example

With example prices of €100 a month and €8,000 once, over 48 months: the subscription costs **€4,800.00**, which is **€3,200.00** less than buying. Break-even is **Month 80**.

## Questions

### Are these Tesla’s current prices?

No. The defaults are round examples. Tesla lists its own prices on its order pages and changes them per country, so check there before you decide.

### Does the break-even month say which option is better?

It only compares totals. A subscription can be cancelled and a purchase stays with the car, so the cheaper total is not the whole story.

### Is anything I enter stored?

No. The calculation runs in your browser and nothing is sent.
