How Interval's Uptrade works
Based on Interval's Buyers' Guide 2026—Amended (correct as of October 3, 2026) and the Deposit Lead Time Guide shown in member accounts.
What changed
On October 3, 2026, Uptrade replaced Interval's Unit-Size Upgrade for members who exchange weeks. Instead of only counting bedrooms, Interval now puts a number on every week and charges by how far apart two weeks are. Points-based exchanges (Club Interval Points, Collection Points) don't use Trading Power.
Two numbers
- Trading Power is the value of the week you deposit. It depends on the resort's rating, the unit size, the season, demand and the date you deposit.
- Exchange Value is the value of the week you want. It uses the same factors except the deposit date.
Interval may adjust both once a year.
Exchange Value ranges
The Buyers' Guide publishes the range for each resort rating and unit size:
| Resort rating | Studio | 1BR | 2BR | 3BR | 4BR+ |
|---|---|---|---|---|---|
| Elite (lotus) | 11–23 | 14–27 | 18–31 | 19–32 | 20–33 |
| Premier (laurel) | 9–22 | 12–25 | 16–29 | 17–30 | 18–31 |
| Select (pineapple) | 7–20 | 10–23 | 14–27 | 15–28 | 16–29 |
| Affiliate (no badge) | 5–18 | 8–21 | 12–25 | 13–26 | 14–27 |
Our reading of the table: each step up in rating adds 2, and the unit-size steps are +3 (Studio to 1BR), +4 (1BR to 2BR), +1 and +1. Within a rating and size, season and demand spread weeks across about 13 values, more than the whole gap between ratings. Interval doesn't state this pattern; it's what the numbers show.
Upgrade fees
You can book a week up to 2 above your Trading Power at no extra charge. Bigger gaps cost:
| Exchange Value minus Trading Power | Upgrade fee |
|---|---|
| Up to +2 | No additional fee |
| From +3 to +5 | $99 |
| From +6 to +8 | $199 |
| From +9 to +11 | $399 |
| +12 and Higher | $599 |
- The fee is on top of the $264 exchange fee, plus tax, and is the same for every membership level.
- You can agree to an upgrade fee on an ongoing request, in case a higher-value week comes through.
- Upgrade fees are refunded only if you cancel within 24 hours.
- Flexchange bookings (30 days or less before check-in) carry no upgrade fee.
- With E-Plus, the upgraded value of your original booking becomes the ceiling for retrades; going higher means buying another upgrade.
Deposit timing
Depositing later cuts Trading Power by a percentage:
| Deposited before check-in | Trading Power kept |
|---|---|
| 181+ days | 100% |
| 91 to 180 days | 95% |
| 61 to 90 days | 90% |
| 31 to 60 days | 85% |
| 7 to 30 days | 80% |
- Depositing more than 181 days ahead already earns full Trading Power.
- The cut is a percentage, so high-value weeks lose more points: at 80%, a 30 becomes 24 but a 15 only 12.
- Interval doesn't say whether it rounds or truncates the result.

What Interval doesn't publish
- Each resort's rating (it's in Interval's online Resort Directory, but not in a list).
- Where a given week falls within its range. That's what member reports fill in.
- How rounding works, and which date Interval uses for a floating week that isn't reserved yet.
