The self-employment tax rate for 2026 is 15.3%, consisting of 12.4% for Social Security (OASDI) and 2.9% for Medicare. For 2026, the statutory Social Security wage base cap is $184,500. Earnings beyond $184,500 are exempt from the 12.4% Social Security portion, but the 2.9% Medicare tax remains uncapped.
Calculate 2026 SE Tax →The IRS allows self-employed individuals to deduct exactly half (50%) of their calculated self-employment tax directly on Schedule 1 (Form 1040, Line 15). This is an above-the-line deduction that reduces your Adjusted Gross Income (AGI), whether you claim the standard deduction or itemize.
Estimate SE Tax Deduction →The statutory IRS Form 1040-ES deadlines for 2026 are: Q1 due April 15, 2026; Q2 due June 15, 2026; Q3 due September 15, 2026; and Q4 due January 15, 2027.
Compute Form 1040-ES Vouchers →W-2 employees receive an employer-paid 7.65% FICA match, subsidized health insurance, paid vacation, sick leave, and unemployment protection. 1099 independent contractors pay the full 15.3% tax themselves and fund all benefits out-of-pocket. Financial planners recommend charging 1.3x to 1.5x your W-2 hourly rate to maintain standard-of-living parity.
Compare 1099 vs W-2 Pay →Yes. Our Invoice Generator utilizes client-side vector PDF rendering via pdf-lib. You can preview and export crisp, high-resolution PDF invoices directly onto your iPhone, iPad, Android phone, or desktop browser in seconds.
Create a PDF Invoice →The standard commercial late payment interest rate in the US is 1.5% per month (equivalent to 18% simple annual interest). To enforce this fee legally, your initial contract, project quote, or invoice terms must state the fee clearly before the invoice becomes delinquent.
Calculate Late Fees & Interest →Yes. Our Quote & Estimate Generator includes a 1-click conversion feature that transfers your client information, scope line items, and pricing directly into the Invoice Generator without re-typing.
Build Client Proposal →While a standard employee schedule totals 2,080 gross hours, independent professionals typically spend 35% to 45% of their time on unbillable administration, pitching, and bookkeeping. After accounting for 3 weeks vacation and holidays, a realistic full-time freelancer bills between 1,000 and 1,200 hours per year.
Calculate Billable Hours →Markup is the percentage added on top of your direct cost to determine the selling price (Profit ÷ Cost). Profit margin is the percentage of the selling price that is kept as profit (Profit ÷ Revenue). For example, a 50% markup on a $100 cost yields a $150 selling price, which produces a 33.3% gross profit margin.
Compare Margin vs Markup →Your break-even point is reached when total revenue equals total fixed plus variable costs. The formula is: Fixed Costs ÷ (Unit Selling Price - Variable Cost per Unit). In consulting, your break-even indicates how many billable client hours you must deliver each month simply to cover your overhead.
Find Break-Even Point →No. Absolutely zero client data, financial figures, hourly rates, invoices, photos, or signature uploads are sent to or stored on any server. DoUrWork operates on a 100% on-device execution model. All calculations, PDF compilations, image resizings, and contrast algorithms run locally inside your browser using HTML5 Canvas and WebAssembly.

Yes. Once loaded, our Progressive Web Application (PWA) caches all client-side logic locally. You can generate invoices, calculate freelance rates, and resize photos without an active internet connection.
Indian government exam portals enforce strict server-side upload limits—typically between 20KB and 50KB for photos and 10KB to 20KB for signatures—as well as exact pixel dimensions (e.g. 3.5cm x 4.5cm). If your file is even 1KB over or under the threshold, the portal halts submission. Our India Copilot resizes and compresses photos locally to land safely within the accepted window.
Open India Document Copilot →Phone camera photos of handwritten signatures often contain shadows, grey paper backgrounds, or faint blue ink. Our signature tool applies on-device thresholding and adaptive contrast enhancement, converting paper background to pure white (#FFFFFF) and darkening ink strokes to crisp black.
Enhance Signature Contrast →Yes. Our tool allows you to merge marksheets, caste certificates, and identity documents into an official A4-standard PDF under 200KB–300KB with zero quality loss and 100% on-device privacy.
