# Staking & Returns
The 200% Base APY, 12-hour epochs, term weights, the renewal ladder, the early-exit rule and the dynamic-reward boundary.
The interest base is `S`, the 72% principal component of the order. The Base APY parameter is **200%**, settled every 12 hours and multiplied by the selected term weight `w`.
```
r_epoch = (S × APY × w) ÷ (365 × 2) per epoch
r_day = (S × APY × w) ÷ 365 per day
R_term = S × APY × w × T ÷ 365 over the full term
```
All three are the same formula — **base × APY × weight** — sliced by time.
## Five terms
Weights lift the 200% Base APY into a 200%–300% band
| Term `T` | Weight `w` | Effective APY parameter | Liquidity condition |
| -------: | ---------: | ----------------------: | ---------------------------------------------------------- |
| 30 days | 1.00 | 200% | Flexible; early exit deducts 10%–15% of the principal base |
| 90 days | 1.10 | 220% | Unlocks at maturity |
| 180 days | 1.20 | 240% | Unlocks at maturity |
| 360 days | 1.35 | 270% | Unlocks at maturity |
| 540 days | 1.50 | 300% | The long term recommended in the approved paper |
## The renewal ladder
The renewal path is `30 → 90 → 180 → 360 → 540 days`. Renewed step by step, it accumulates roughly **1,200–1,400 locked days**.
A user can also take the other path: redeem at maturity and open a fresh 540-day order. **Both paths end at the same weight; the liquidity along the way is completely different.**
## Early exit
Only the 30-day term supports early exit:
```
Refund = S × (1 − λ), where λ is 10%–15%
```
The exact value of λ inside that band has not been published. With `S = 21,600 USDT`, an early exit returns **18,360–19,440 USDT**.
## Dynamic rewards
The dynamic component establishes levels from **community contribution and team performance**, and applies a **Differential Matching Bonus** between adjacent levels, settled in the **same epoch** as static rewards.
**The Reward Payout Ratio band is 150%–200%**, adjustable by issuance round and market conditions.
Level names, qualification thresholds, per-level differential rates and team-performance boundaries have not been published, so **an individual dynamic reward cannot be calculated from this paper** ([Open Parameters](/nexon-docs/appendix/open-parameters.md), OP-T04).
{% hint style="info" %}
**Both 200% and the 150%–200% band are adjustable protocol parameters, and both may change by issuance round and market conditions.** Every order and every epoch records the parameter version in force at the time, so a later change does not rewrite a historical accrual. An interface should be able to tell a user which version applied when their order executed.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://nexon-3.gitbook.io/nexon-docs/part-v-economics/05-tokenomics/staking-and-returns.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
