Fix Remaining Balance Bug For EOY & Custom Cycles

Understanding the Remaining Balance Issue

If you've been using our budgeting tool, you might have encountered a peculiar issue related to the remaining balance when dealing with specific cycle configurations. This isn't just a minor glitch; it affects how accurately you track your financial progress, especially around the End of Year (EOY) and when you opt for custom budget cycles. We've received reports and confirmed that the remaining balance calculation falters under these conditions, leading to discrepancies that can be quite confusing. The core problem lies in how the system computes and displays the net total of savings up to a certain point in time. When a cycle aligns perfectly with the calendar year (January to December), and you reach the end of December, the system, instead of showing the actual remaining balance, displays the entire ending balance. This means you're seeing the total amount at the end of the period, not what's left to be accounted for within that cycle's scope. Similarly, for custom cycles, let's say from March through February of the next year, the behavior is even more erratic. You might see an entirely incorrect balance, or worse, misleading text that refers to years in the past or future, or suggests the cycle is coming to an end when it's not. This inconsistency can significantly undermine your trust in the tool's accuracy and make financial planning more challenging.

Why Accurate Remaining Balance Matters

The remaining balance is a critical metric for anyone serious about managing their finances. It's not just a number; it's a snapshot of your financial health at a specific moment, indicating how much of your budget is left to spend or save within a given period. When this figure is incorrect, especially during significant financial checkpoints like the End of Year (EOY) or within custom budget cycles, it can lead to poor decision-making. Imagine planning your holiday spending based on an inflated remaining balance, only to realize later that you've overspent because the initial calculation was wrong. Or perhaps you're trying to stick to a specific savings goal within a custom cycle, and the tool misrepresents your progress, demotivating you or leading you to abandon your targets prematurely. The expected behavior, as users rightly anticipate, is for the tool to always display the net total of savings up to the end of the current cycle. This means if your cycle ends in March, the remaining balance should reflect your financial standing as of the end of March, accurately representing your savings and expenditures within that defined period. The bug we're discussing here deviates from this fundamental expectation. It replaces a clear, actionable number with either the full ending balance (making it seem like there's more available than there actually is within the cycle's context) or with confusing textual placeholders. This directly impacts the utility of the tool for effective budgeting and financial oversight, turning what should be a source of clarity into a point of confusion and potential financial missteps.

Diving Deeper into the Bug Scenarios

Let's break down the specific scenarios where the remaining balance calculation goes awry. The first problematic situation arises when a cycle concludes on its End of Year (EOY) date. For instance, if your budget cycle runs from January 1st to December 31st, reaching December 31st should ideally show the final remaining balance for that cycle. However, the bug causes the system to display the entire ending balance instead. This is misleading because the ending balance typically represents the total accumulated funds at the very end, which might not accurately reflect the net savings within that specific cycle if there were carry-overs or other complexities. The user expects to see the final remaining amount for the 12-month period, not just a general end-of-period figure. The second, and arguably more confusing, scenario involves custom cycles. These are cycles that don't necessarily align with the standard calendar year, perhaps running from March to February, or any other arbitrary 12-month period. In these cases, the remaining balance display becomes even more unreliable. The system might show an incorrect balance altogether, making it impossible to gauge your financial standing. More jarringly, it can display placeholder text that nonsensically refers to years in the past or future, or even suggests the cycle is nearing its end when it's actually in full swing. For example, if you're in a March-to-February cycle, you might see text like "Balance for 2023" when you're currently in 2024, or "Cycle ending soon" when you're only a few months in. This kind of output is not only unhelpful but actively detrimental to effective financial management. The expected behavior across all cycle types is straightforward: always display the net total of savings until the end of the current cycle. This ensures consistency and provides users with reliable data for their budgeting decisions, regardless of whether they use standard or custom periods.

Steps to Reproduce and Environment

While the specific steps to reproduce this bug aren't detailed in the initial report, the conditions are clear: the issue manifests when a budget cycle concludes on its End of Year (EOY) date or when a custom cycle is configured. To observe the EOY issue, one would typically set up a budget with a standard January-December cycle and navigate to the end of the year. The expectation is to see the final remaining balance for that specific year's cycle. Instead, the bug presents the overall ending balance. For custom cycles, the reproduction would involve setting a non-standard start and end date for the budget period (e.g., March 1st to February 28th of the following year). Upon reaching different points within this custom cycle, particularly as the end date approaches or even mid-cycle, users would observe the incorrect balance figures or the nonsensical text replacements.
