How to Calculate Profit on Dual Investment Structured Products

Dual investment lets you subscribe with one asset — say BTC or ETH — lock it for days or weeks at a quoted APY, and at settlement receive either your original asset back plus interest, or the paired asset at a pre-agreed strike price.

It looks like free yield, but real profit depends on where the price settles relative to the strike — not just the APY. Quoted rates also ignore the friction of moving funds: the same fees and slippage in our crypto arbitrage profit guide.

Below: the mechanics, the profit formula, and a fully worked example with three settlement scenarios — so you see the genuine return and the genuine trade-off before subscribing.

How Dual Investment Works: Sell-High and Buy-Low

Four parts define every dual investment: the subscription currency (your deposit), the strike price (the conversion trigger), the APY (your fixed rate), and the tenor (the lock-up, usually 1–30 days). At settlement the exchange compares market price with the strike and pays the dictated asset.

Sell-high: target a higher price for your coins

Deposit the base asset (e.g. BTC) and pick a strike above the current price. Settle at or above it: you get your BTC back plus interest — a limit sell that paid yield while you waited. Settle below: your BTC converts into the quote asset (e.g. USDT) at the strike, plus interest.

Buy-low: target a cheaper entry

Buy-low reverses it: deposit the quote asset (e.g. USDT) and pick a strike below the current price. Settle at or below it and your USDT converts into BTC at the strike — a limit buy that earned yield. The example below uses sell-high.

The Profit Formula: Interest Plus Settlement Outcome

Profit has two components. First, the interest — fixed and simple:

Interest = subscription amount × APY × (tenor in days ÷ 365)

It is paid in the settlement asset. The second component is the settlement outcome itself: you either keep your original asset and ride its price move, or you are converted at the strike, locking in a sale or purchase at that price.

So profit = settlement value − your subscription's dollar value at deposit, benchmarked against simply holding. Structurally, sell-high is a covered call — the same payoff as in our worked example of how crypto options calls and puts work.

Worked Example: 0.5 BTC at $80,000, $84,000 Strike, 10% APY, 7 Days

You subscribe 0.5 BTC at $80,000 — a $40,000 subscription — into a sell-high plan: $84,000 strike, 10% APY, 7-day tenor.

Interest: 0.5 × 10% × (7 ÷ 365) = 0.0009589 BTC (≈$76.71 at subscription price), which annualizes to exactly the quoted 10%. Three settlement scenarios:

Key takeaway: In Scenario A the product beats holding by exactly the interest — when the strike is never triggered, the APY is pure extra return.

Key takeaway: Scenarios B and C pay identically: below the strike your outcome is frozen at the strike conversion, which floors your dollar result but strands you in USDT if the market rebounds.

Effective Yield vs the Real Opportunity Cost

Beginners quote the APY as the return. Sharper: total profit ÷ subscription value, annualized. In Scenario B that is ($2,080.55 ÷ $40,000) × (365 ÷ 7) ≈ 271% annualized — the strike conversion did most of the work, not the 10% APY.

The hidden cost is Scenario C: you hold $42,080.55 in USDT while the holder still owns 0.5 BTC. If BTC rebounds to $95,000, their coins are worth $47,500 — you buy back higher, spending more dollars for fewer sats. The yield was the premium for surrendering that upside.

Two checks before subscribing: pick a strike you would genuinely trade at — it is a real order, not decoration. And confirm the settlement price source and timing on the exchange's product page; most venues settle against an index price at a fixed time. Track the reference on CoinGecko through the tenor, and read the Binance Academy explainer on dual investment for the mechanics.

Conclusion

Dual investment profit is fixed interest plus the settlement outcome at the strike. The APY tells you the interest; the strike tells you what you may be forced to sell or buy. Model all three scenarios, subscribe only at a strike you would trade at willingly — and it becomes what it should be: yield on a trade you already wanted.
