Enhancing clarity and precision in daily interest calculations
At FinForta, interest is calculated and credited daily. This approach ensures steady accumulation of returns and allows investors to see their earnings grow day by day.
Recently, some users noticed small differences in displayed daily interest amounts - for example, seeing €0.35 on one day and €0.36 on another - and asked why the numbers did not always appear identical.
We appreciate this feedback. Transparency, accuracy, and investor trust are core values at FinForta, and we take such questions seriously.
Why daily interest amounts may look different
Daily interest calculations often result in values with more than two decimal places.
For example:
Investment amount: €1,000
Annual return: 13% p.a.
Investment period: 1 year
Calculation:
Yearly interest: €1,000 × 13% = €130
Daily interest: €130 ÷ 365 = €0.35616 per day
From a financial and accounting perspective, this value is precise and correct.
However, most financial interfaces display only two decimal places, which means the amount may appear as €0.35 or €0.36 depending on rounding rules.
The interest calculation logic itself has always been correct and remains unchanged.
The differences some users noticed were related only to how rounded values were displayed, not to how interest was earned.
How daily interest is calculated
The daily interest formula used by FinForta is straightforward and transparent:
EARNED_INTEREST = INVESTMENT_AMOUNT × INTEREST_RATE ÷ 365
What has changed is not the formula, but how daily rounding is applied - to make it fully consistent, predictable, and aligned with accounting best practices.
How rounding works
To provide full clarity, here are two practical examples showing how daily rounding was previously applied and how it works today.
Example 1: €500 invested at 13% p.a.
Calculation:
€500 × 0.13 ÷ 365 = €0.17808 per day
Previously:
In some cases, this value was rounded up
The daily interest could be displayed as €0.18
Now:
A consistent accounting rounding rule is applied down
The daily interest is displayed as €0.17
The fractional part is not lost and is tracked internally
Example 2: €1,000 invested at 13% p.a.
Calculation:
€1,000 × 0.13 ÷ 365 = €0.3561 per day
Previously and now:
The value is rounded down to €0.35
In this case, the rounding logic has not changed
Why this change improves transparency
It is important to clearly state what does and does not change as a result of this update.
What does not change:
The interest calculation formula
Project APY and investment terms
The total return earned by investors
What improves:
A single, predictable rounding rule at the daily level
Clear and verifiable daily interest values
Accounting consistency across all investments
This approach ensures that daily interest values are easier to understand and verify, without altering the economics of investments.
Automatic monthly interest reconciliation
To further protect investor interests, FinForta has implemented an automatic monthly reconciliation mechanism.
At the end of each month:
All daily interest credited during the month is reviewed
Any differences caused by daily rounding are identified
If even a minimal amount of interest is missing, it is automatically credited to the investor’s wallet
This guarantees that 100% of earned interest is always paid, without requiring any action from the investor.
Our commitment to investors
These improvements reflect our ongoing commitment to:
Full transparency
Accurate, investor-first accounting
Clear and proactive communication
We believe investors should not only earn returns, but also fully understand and trust how those returns are calculated.
Thank you for your feedback and trust - it helps us continue improving FinForta.
