Your Digital Surge wallet makes it easy to track how your crypto is performing over time.
For each coin and for your overall portfolio, you’ll see two main Return On Investment (ROI) figures:
Total Return
Day Return
These give you a clear view of how your crypto’s value has changed, both overall and during the current day.
All returns are calculated using the First In, First Out (FIFO) method and are based on unrealised gains, meaning they show the current market performance of the crypto you still hold, not what you’ve already sold or withdrawn.
Total Return
Total Return shows your overall unrealised gain or loss, either for a specific asset (for example, ETH) or for your entire portfolio.
It represents the difference between your holdings’ current total value and their cost basis, using FIFO.
Your Total Return updates automatically as market prices move or as you buy, sell, deposit, or withdraw crypto.
You’ll see Total Return displayed as both:
A dollar amount – showing your total unrealised gain or loss in AUD, and
A percentage – showing how much your current holdings have changed in value overall
Day Return
Day Return measures how much your portfolio or an individual asset has changed in value since midnight (AEST).
It compares your wallet’s total value (or a single coin’s value) at midnight to its current value.
You’ll see Day Return displayed as both:
A dollar amount – showing today’s total change in AUD, and
A percentage – showing your daily percentage gain or loss.
This gives you a quick, real-time view of your daily performance, updated automatically throughout the day as market prices change.
How FIFO Works
Digital Surge uses the First In, First Out (FIFO) method to calculate your ROI and ensure all performance figures are consistent and transparent.
FIFO is a standard accounting method that assumes the first crypto you bought or deposited is the first one used when calculating returns.
In other words, when you make multiple purchases or deposits of the same asset, FIFO looks at your transactions in the order they occurred — starting with the earliest.
How FIFO affects your return calculations
Oldest assets are counted first: When you sell, withdraw, or move crypto out of your wallet, the system assumes you’re using or selling your oldest holdings first.
Newer assets remain active: Any crypto you bought or deposited more recently stays in your wallet and continues to be included in your ROI calculation.
Accurate cost tracking: FIFO allows each unit of crypto to keep a defined cost basis — the value used to calculate profit or loss — so your returns stay precise and consistent.
Deposits
When you deposit crypto into your Digital Surge wallet, that transaction is recorded with a cost basis equal to the market value at the time of deposit.
This ensures that your ROI reflects the performance of that cryptocurrency from the moment it enters your wallet, even if you originally purchased it elsewhere or at a different time.
Withdrawals
When you withdraw crypto, it’s treated as if you’ve sold that portion at the current market price.
The withdrawn amount is removed from your wallet and no longer included in future return calculations.
This means your ROI always represents the performance of your current holdings only, not any assets you’ve already moved out.
Automatic and continuous tracking
Your returns are updated in real-time as market prices change or when you buy, sell, deposit, or withdraw crypto.
There’s no need to manually adjust or reset anything — FIFO ensures your ROI calculations always reflect your active holdings accurately and automatically.
Example 1 - Simple Buy and Hold
Example 1 - Simple Buy and Hold
You buy 1 ETH at $3,000.
A few days later, the market price of ETH rises to $3,600.
Your Total Return shows the unrealised profit (the increase in value) of your ETH compared to what you paid for it.
(3,600 − 3,000) ÷ 3,000 × 100 = 20%
The value of your ETH holdings has increased by $600 (20%).
Example 2 - Two Purchases and One Sale
Example 2 - Two Purchases and One Sale
You make the following transactions:
Buy 1 ETH at $2,500
Buy another 1 ETH at $3,000
Sell 1 ETH at $3,500 (Current market price)
Digital Surge uses the First In, First Out (FIFO) method, which means your first purchase (the 1 ETH bought at $2,500) is used for this sale.
Realised Gain (on the ETH sold):
(3,500−2,500) = $1,000
You’ve made a realised gain of $1,000 on the ETH you sold.
Unrealised Gain (on the ETH still held):
Your remaining 1 ETH was bought at $3,000 and is now worth $3,500.
(3,500−3,000) ÷ 3,000 × 100 = 16.7%
Your unrealised gain is $500 (16.7%).
Your Total Return reflects only the unrealised gain on the ETH remaining in your wallet.
Example 3 - Multiple Purchases and a Partial Withdrawal
Example 3 - Multiple Purchases and a Partial Withdrawal
You make the following transactions:
Buy 1 ETH at $2,000
Buy 1 ETH at $2,500
Buy 1 ETH at $3,000
You now hold 3 ETH in total.
Later, when the ETH market price rises to $3,500, you withdraw 1.5 ETH to an external wallet.
Digital Surge uses the First In, First Out (FIFO) method, which means your oldest ETH purchases are used first when calculating returns.
In this case, the withdrawal comes from the 1 ETH bought at $2,000 and 0.5 ETH bought at $2,500.
Realised Gain (on the withdrawn ETH):
1 ETH bought at $2,000, withdrawn at $3,500:
(3,500 − 2,000) = $1,500
0.5 ETH bought at $2,500, withdrawn at $3,500:
(3,500 − 2,500) × 0.5 = $500
Total Realised Gain:
1,500 + 500 = $2,000
Your realised gain on the withdrawn ETH is $2,000.
After the withdrawal, you still hold 1.5 ETH in your wallet:
0.5 ETH from the $2,500 purchase
1 ETH from the $3,000 purchase
Your cost basis for the remaining ETH is:
(2,500 × 0.5) + (3,000 × 1) = 1,250 + 3,000 = $4,250
At the current market price of $3,500 per ETH, your remaining holdings are worth:
3,500 × 1.5 = $5,250
Unrealised Gain (Value − Cost Basis):
5,250 − 4,250 = $1,000
Unrealised Gain Percentage (Gain ÷ Cost Basis × 100):
(1,000 ÷ 4,250) × 100 = 23.5%
Your unrealised gain is $1,000 (23.5%), based on a cost basis of $4,250 for your remaining 1.5 ETH.
Your Total Return now reflects the unrealised gain of $1,000 (23.5%) on the ETH remaining in your wallet, while the realised gain of $2,000 from the withdrawn portion is no longer included in your wallet’s return calculations.
Example 4 - Purchase, Full Withdrawal, and Later Redeposit
Example 4 - Purchase, Full Withdrawal, and Later Redeposit
You buy 1 ETH at $2,000 on Digital Surge.
Later, you withdraw the full 1 ETH to an external wallet.
Because you no longer hold ETH on the platform, your Total Return resets to zero — there are no remaining holdings to calculate performance from.
While your ETH is outside Digital Surge, its value continues to change.
After some time, the market price increases to $3,000, and you decide to re-deposit 1 ETH back into your Digital Surge wallet.
When you make this deposit, Digital Surge records the cost basis at the market value at the time of deposit, which in this case is $3,000.
Your Total Return is now $0, as the deposit is treated as a new acquisition at its current market value.
Later, the market price of ETH rises again to $3,600.
Your unrealised gain is now calculated from the deposit cost basis of $3,000.
Unrealised Gain (Value − Cost Basis):
(3,600 − 3,000) = $600
Unrealised Gain Percentage (Gain ÷ Cost Basis × 100):
(600 ÷ 3,000) × 100 = 20%
Your unrealised gain is $600 (20%), based on the cost basis of $3,000 at the time of redeposit.
Additional Note:
Even though you originally purchased the ETH at $2,000, Digital Surge can only track transactions made on the platform.
When you withdraw and later re-deposit crypto, it’s treated as a new acquisition at the market value at the time of deposit.
This ensures your Total Return reflects only the performance of the assets held within your Digital Surge wallet.
Example 5 - Multiple Buys and Sells
Example 5 - Multiple Buys and Sells
You make the following transactions:
Buy 1 ETH at $2,000
Buy 1 ETH at $4,000
Sell 1 ETH at $3,000
Buy 1 ETH at $5,000
Sell 1 ETH at $6,000
Digital Surge uses the First In, First Out (FIFO) method, which means your oldest ETH purchases are used first when calculating gains or losses.
Sale 1 – 1 ETH sold at $3,000
Your first sale uses the first ETH you bought at $2,000.
(3,000 − 2,000) = $1,000
You have a realised gain of $1,000 (50%) on this sale.
Sale 2 – 1 ETH sold at $6,000
After the first sale, FIFO applies the next oldest ETH purchase.
This sale uses the ETH bought at $4,000.
(6,000 − 4,000) = $2,000
You have a realised gain of $2,000 (50%) on this sale.
If the market had dropped and you sold at $3,500 instead, FIFO would calculate:
(3,500 − 4,000) = −$500
This would be a realised loss of $500 (–12.5%).
Remaining Holdings
You still hold 1 ETH, which was bought at $5,000.
The current market price is $7,000.
Unrealised Gain (Value − Cost Basis):
(7,000 − 5,000) = $2,000
Unrealised Gain Percentage (Gain ÷ Cost Basis × 100):
(2,000 ÷ 5,000) × 100 = 40%
Your unrealised gain is $2,000 (40%), based on a cost basis of $5,000 for your remaining ETH.
This example shows how FIFO applies your oldest purchases first for each sale, calculating realised gains or losses for completed transactions, while continuing to track unrealised performance for the ETH still held in your wallet.
These examples are simplified to help explain how calculations work and are for educational purposes only.
Important Notes
Total Return and Day Return only track performance for crypto held within your Digital Surge wallet.
Once crypto leaves your wallet, its performance can’t be tracked until it’s deposited back in.
When you re-deposit crypto, its cost basis is set to its AUD value at the time of deposit.
Displayed return figures are based on the buy price of the asset on Digital Surge.
These figures are informational only and do not represent realised profits, tax outcomes, or financial advice.
