Keep what the yield earns
An illustrative yield-bearing position earns a flat simple annual yield for an entered holding period. Entry fees, fixed entry costs and gas come out of the same starting budget, so only the remainder earns yield. Exit fees then reduce ending wealth. Compare the cost schedule without increasing the budget, assumed yield or holding period.
Every mission compares policies using the same starting resources and shared conditions. The public browser engine calculates the results from entered assumptions, without an account or live market feed.
Run this free missionThe decision to compare
Do the declared costs leave positive net income?
- Keep the reference costs. Repeat the entered cost schedule to see gross income, costs and ending wealth separately.
- Test a zero exit fee. Assume an exit fee of 0%. This tests a hypothetical contract condition; no available product or fee waiver is asserted.
- Enter a different cost schedule. Change the assumed entry, fixed, gas or exit costs while keeping starting budget, simple annual yield and holding period identical.
Asset identity and cash access
Asset identity, price and usable cash are separate questions in this mission.
- Asset identity
- A generic illustrative yield-bearing position, with all amounts measured in USD. It is not a specified stablecoin, fund, vault or lending protocol.
- Yield mechanism
- Flat simple annual yield on the principal left after entry costs, using actual days divided by 365. This is a yield assumption, not compounding APY or a quote.
- Access and loss
- Ending wealth is modelled value. This calculation does not verify withdrawal access, price stability, legal rights, custody or principal protection.
- What can change
- Only the declared costs change across plans. The budget, yield and holding period remain identical.
A calculated reference example
The $100,000.00 starting budget leaves $99,650.00 earning the entered 5.00% simple annual rate after entry costs. Over 30 days the gross interest is $409.52. Total declared entry and exit costs are $550.12; ending wealth is $99,859.40. Net income is -$140.60, so the reference loses money after costs despite the positive gross rate. The calculation does not establish withdrawal access or principal protection.
The worked example uses the published default inputs and Go model yieldguard-experiments-1.2.0. The scenario starts on 2026-01-01; that date is an illustrative calendar origin, not a market observation date.

Sources and interpretation limits
No live rate, specific coin, issuer, protocol or legal classification is inferred. Taxes, token-price changes, slashing, insolvency and withdrawal queues are not modelled. A positive result is conditional arithmetic, not an investment recommendation.
Primary documentation explains mechanisms and product distinctions. The documentation does not verify these inputs or identify the illustration as a named product.
- Illustrative user assumptions; no live market data or calibrated forecast.
- Results apply only to the declared mechanisms, horizon and search bounds.
- Entry percentage fee, fixed cost and assumed USD-equivalent gas cost are paid from the same starting budget. Only the remaining principal earns simple ACT/365 interest; the exit fee applies to principal plus accrued interest at the horizon. Costs must not exceed the budget.
- Flat entered rate and USD valuation only: no live APY, compounding, reward token, token-price change, tax, protocol failure or withdrawal restriction. The value path is not available cash. Gas is a stated USD-equivalent cost, not native-token execution eligibility.
- The break-even gross annual rate uses the algebra before interest and exit-fee cent rounding. It is undefined with no invested principal or a 100% exit fee; rounding can shift the exact cent-level threshold. Annualised net return is a simple scaling, not a reinvestable APY.
