Give every monthly dollar a job, then see the cushion left over.
Formula: income − bills − flexible spending − saving − extra debt.
Explore how contributions, time, and a hypothetical return change a long-term scenario.
Monthly rate = (1 + annual return / 100)^(1/12) − 1. Contributions arrive at month-end. A 7% assumption means 7% yearly growth before contributions. Investing can lose value.
Calculate the share of your combined revolving limits represented by reported balances.
Use balances reported to credit bureaus, which may differ from today’s app balance.
Turn an income target and realistic billable capacity into a starting hourly floor.
Formula: (annual take-home goal + annual business costs + tax reserve) ÷ (weekly billable hours × working weeks per year). Billable hours and working weeks must be greater than zero. The result rounds to the nearest whole dollar per hour. The reserve is the entered percentage of the take-home goal; it is a planning buffer, not a calculation of tax owed.
Use a simple work estimate to compare the same lift across sessions.
Formula: working sets × reps × load. Warm-ups are usually tracked separately.
