Time card math for solo work

What this calculation answers

A solopreneur time card answers a practical question: how many hours did you work, and how many of those hours belong on an invoice, project report, or business record? The core calculation adds work spans, subtracts nonworking breaks, converts minutes to decimal hours, and multiplies billable hours by the agreed rate. That works for consulting, creative work, repair jobs, coaching, admin support, and part-time gig work.

The legal frame changes by worker status. A solopreneur working in business for themselves is generally an independent contractor or self-employed person, so FLSA minimum wage, overtime, and recordkeeping protections for covered employees do not apply to that person's own work. If you use the same time-card setup for hired covered nonexempt employees, the federal baseline requires overtime after 40 hours in a fixed workweek unless an exemption applies.

Formula for billable totals

Start with each work span: clock-out time minus clock-in time, minus nonworking breaks. Convert minutes with minutes ÷ 60, so 30 minutes equals 0.5 hours and 15 minutes equals 0.25 hours. For overnight work, add 24 hours when the clock-out time is earlier than the clock-in time. A 10:00 PM to 6:00 AM span equals 8 hours.

For example, a solo marketing consultant bills $86 per hour and records client work of 7, 6, 9, 5, and 8 hours across the week. The billable total is 35 hours. The invoice subtotal is 35 × $86 = $3,010. If the consultant also spends 4 nonbillable hours on proposals and bookkeeping, those hours belong in business records, but they do not increase the client invoice.

Separate owner records from payroll rules

The common mistake is treating every time-card total like payroll. For your own self-employed work, the time card supports pricing, invoices, project profitability, and business records. The IRS accepts any recordkeeping system that clearly shows business income and expenses, and invoices are supporting documents for gross receipts and expenses.

Payroll rules still matter when the time card covers someone you hire. Federal law does not require adult lunch or coffee breaks, but state law, contract terms, or employer policy can add rules. For covered employees, short breaks of about 5 to 20 minutes are compensable hours worked, and a bona fide meal period is unpaid only when the worker is completely relieved from duty.

Calculator versus managed workflow

A one-off calculation is enough when you need a quick invoice subtotal, a project estimate check, or a weekly self-review. Keep the inputs simple: start time, end time, unpaid break time, billable category, and hourly rate. Save the result with the invoice or project note so the number can be traced later.

A managed workflow becomes the better answer when the same work repeats across clients, tools, tasks, or subcontractors. Everhour embeds tracking controls inside supported project tools, syncs project and task metadata, and keeps timesheets and budgets visible in work tools. That reduces duplicate entry when billable hours need approval, billing review, or a clean handoff to accounting.

Frequently Asked Questions

Do solopreneurs need overtime on their own time cards?

A solopreneur working in business for themselves is generally not covered by the FLSA minimum wage, overtime, and recordkeeping protections that apply to covered employees. The time card still matters for invoices, business income records, pricing, and project profitability. If the same setup tracks hired covered nonexempt employees, use the federal baseline of overtime after 40 hours in a fixed workweek unless an exemption applies.

How should overnight solo work be calculated?

An overnight span uses the same elapsed-time rule as any other time entry, with one extra step. Add 24 hours when the clock-out time is earlier than the clock-in time. A span from 10:00 PM to 6:00 AM equals 8 hours before subtracting any nonworking break that does not belong in the billable total.

Which breaks should a solopreneur subtract?

Subtract breaks only when they are not part of the work being billed or recorded. A 30-minute lunch away from client work normally comes out of the billable total. A short pause that the client contract treats as billable stays in the invoice calculation. For covered employees, short employer-provided breaks of about 5 to 20 minutes count as compensable hours worked under federal guidance.

Why does decimal time matter for invoices?

Invoices multiply hours by a rate, so hours:minutes must convert to decimal hours before billing. Use minutes ÷ 60. Thirty minutes equals 0.5 hours, 45 minutes equals 0.75 hours, and 1 hour 15 minutes equals 1.25 hours. This prevents base-100 mistakes, such as treating 1:30 as 1.30 hours instead of 1.5 hours.

Which time-card records support self-employed taxes?

Records should clearly show business income and expenses. Time cards support that record when they connect dates, clients, projects, hours, rates, invoice amounts, and reimbursable expenses. A self-employed person generally must file an income tax return when net earnings from self-employment are $400 or more, after subtracting business expenses from business income to determine net profit or loss.

How does Everhour connect solopreneur time cards with work tools?

Everhour integrates with major project management and accounting tools, adds tracking controls inside supported workflows, and syncs project and task metadata into one time layer. A solopreneur can track billable work where tasks already live, then use those entries for timesheets, budgets, and billing review without retyping the same project details.
