Net Worth Tracker for People Paying Off Credit Card Debt

It is a balance-sheet tool that records all assets and liabilities — including credit card balances at full current value — to show your true net worth, even when it is negative.

At 21.52% average APR, a $10,895 balance adds roughly $2,344 in annual interest that directly reduces your net worth if unpaid.

It is your annual credit card interest cost divided by the absolute value of your current net worth, expressed as a percentage — showing how much of your net worth deficit is consumed by interest each year.

It is a balance-sheet tool that records all assets and liabilities — including credit card balances at full current value — to show your true net worth, even when it is negative.

A net worth tracker in this context goes beyond listing your savings and investments. It requires inputting every credit card balance, loan balance, and other liability alongside your assets. U.S. credit card balances totaled $1.252 trillion in Q1 2026, with average balance-carrying households owing $10,895. When 47% of cardholders carry a balance monthly, the resulting net worth figure is often negative. The tracker's job is to show that negative number accurately and update it each month so you can measure real direction of travel.

At 21.52% average APR, a $10,895 balance adds roughly $2,344 in annual interest that directly reduces your net worth if unpaid.

Interest accrues daily regardless of your spending behavior. At the Q1 2026 Federal Reserve G.19 average APR of 21.52%, a $10,895 balance costs approximately $6.41 per day in interest. Over a year, that is $2,344 in additional liability — money that goes nowhere except into the lender's revenue. The CFPB reported $160 billion in credit card interest charged in 2024 alone. If your monthly payments do not exceed both the minimum and the accruing interest, your balance grows even as you pay, and your net worth deteriorates regardless of what your asset side looks like.

It is your annual credit card interest cost divided by the absolute value of your current net worth, expressed as a percentage — showing how much of your net worth deficit is consumed by interest each year.

The Credit Card Debt-Drag Index quantifies the rate at which interest is compounding your net worth deficit. The formula is: (cc_balance × apr) ÷ |net_worth| × 100. Using Q1 2026 averages — $10,895 balance, 21.52% APR, $3,500 in assets, $5,000 in other liabilities — the index calculates to 18.9%. That means interest alone would deepen the net worth deficit by nearly 19% of its current size in one year. As the balance falls, both the interest cost and the deficit shrink, causing the index to compress — which is the measurable signal that payoff momentum is real.

Monthly, on the same calendar date, is the right cadence — frequent enough to catch trends, infrequent enough that noise doesn't dominate signal.

Daily balance fluctuations from pending transactions, statement timing, and payment processing create noise that obscures the real trend. A monthly snapshot taken on the same date each month — ideally the day after your payment posts — gives you a clean time series. The key comparison is not just the net worth number itself, but whether the month-over-month improvement exceeds the interest you paid. If it does not, your balance is still growing in effective terms. Sixty-one percent of cardholders have been in debt for at least one year, which suggests that irregular tracking — or no tracking — fails to surface this signal in time.

Yes — MFFT displays negative net worth as a negative number and charts the upward trajectory from that baseline without any cosmetic adjustments.

Many tools orient their UI around positive-balance users, which creates a misleading experience for anyone whose liabilities exceed assets. MFFT treats the net worth calculation as a straight balance-sheet exercise: total assets minus total liabilities, with the result displayed accurately regardless of sign. The month-over-month chart anchors at your actual starting negative number, so the visual direction of travel is meaningful. The Debt-Drag Index is also displayed alongside the net worth figure, giving you a two-number summary: where you stand today and how fast the interest cost is affecting your position.

You need the current balance (not statement balance) and APR for each credit card, plus current values for all assets and all other liabilities.

The most common error is using statement balances rather than current balances — the difference can be hundreds of dollars mid-cycle. For assets, enter checking, savings, brokerage, and retirement account values; for physical assets like a car, use current market value minus any remaining loan balance, not the full asset value. For liabilities, include every credit card balance, the personal loan or auto loan balance, and any other debt. The Federal Reserve G.19 reports that the average APR on interest-bearing credit card accounts was 21.52% in Q1 2026, but your specific card APR will differ — use your actual rate, not the average, for the Debt-Drag Index calculation.

The CFPB identifies 13% of cardholders as persistent debtors — paying more in interest than principal — and measurement gaps are a significant contributing factor.

Persistent debt, defined by the CFPB as paying more in interest than reducing principal in a calendar year, affects 13% of all cardholders. The CFPB's 2025 Consumer Credit Card Market Report notes that these borrowers often lack visibility into how their payment amounts compare to accruing interest. When a cardholder believes they are making progress but their balance is barely moving, the issue is frequently that minimum payments are nearly consumed by interest — a dynamic that a net worth tracker surfaces immediately when you compare month-over-month net worth change against interest paid. The tracker does not fix the math, but it makes the math impossible to ignore.

MFFT automates the monthly recalculation, applies the Federal Reserve default APR for the Debt-Drag Index, and visualizes the net worth trend from a negative baseline without manual formula management.

A spreadsheet requires you to rebuild or update formulas each month, manually enter the current Federal Reserve APR, and design the chart yourself with a negative y-axis starting point — steps that introduce errors and create friction that leads to inconsistent tracking. MFFT pulls the calculation layer into the product: enter your balances, get your net worth and Debt-Drag Index. The historical chart is generated automatically from your monthly entries, anchored at whatever negative number you started with. For the 61% of credit card debt holders who have been in debt at least a year, eliminating that friction matters — because irregular tracking produces incomplete data, and incomplete data produces poor payment decisions.
