01 — Pricing math

Money & Pricing

Thirteen calculators for the numbers that decide whether a job was worth doing.

Profit Margin Calculator

Enter what something costs you and what you charge. Margin is the share of the sale you keep; markup is how much you added on top of cost. They are different numbers and mixing them up is how shops end up working for free.

What do you know?

Materials, product cost, subcontractor — what leaves your pocket.

Rent, insurance, software, truck payment — the bills that show up whether you sell or not.

Hourly Rate Calculator

Most owners guess their rate by looking at competitors. This works backward from your life instead: what you need to take home, what the business costs to run, and how many hours you can honestly bill after driving, quoting and paperwork.

Self-employment plus income tax. Ask your accountant for your real number; 25–30% is a common starting point.

Payment Fee Calculator

Card processors take a percentage plus a flat cut of every invoice. Small on one job, real money over a year. This shows the bite, and what to charge if you want the full amount to land in your account.

Published rates change and yours may differ by plan or card type. Check your statement before you build a price around it.

Break-Even Calculator

The point where your sales stop paying for themselves and start paying you. Everything above this line each month is profit; everything below it is a job that cost you money to do.

Rent, insurance, software, salaries — costs that show up whether you sell anything or not.

What each additional sale costs you — materials, commission, processing.

Markup vs. Margin Calculator

The single most common pricing mistake: treating markup and margin as the same number. A 50% markup is only a 33% margin. Enter one and see both, in plain numbers.

What are you entering?

Add a cost to see the actual price and profit, not just the percentages.

Sales Tax Calculator

Add tax to a price, or work backward from a total that already includes it — useful when a customer pays a round number and you need to know what part of it was tax.

Direction

Discount Calculator

Figure out a sale price fast, in percent off or dollars off, and see exactly what a customer saves.

Discount type

Commission Calculator

What a salesperson, contractor or affiliate takes home from a sale, and what the business keeps after paying it.

Overtime Pay Calculator

Regular hours, overtime hours and what a week actually adds up to at time-and-a-half or whatever multiplier applies.

Paycheck Calculator

A rough estimate of take-home pay from an hourly rate or salary. It is not a real paystub — your actual withholding depends on your W-4, state and benefits — but it gets you in the right neighborhood.

Pay type

Health insurance, retirement contributions and the like.

Recurring Revenue Calculator

Turn a subscriber count and price into MRR and ARR, and see what churn quietly costs you over a year if you stopped signing up new customers.

The share of subscribers who cancel each month.

Project Cost Calculator

Labor, materials and overhead rolled into one estimate, plus the price that hits the profit margin you actually want.

Invoice Due Date Calculator

Enter an invoice date and your payment terms, and get the actual due date — plus whether it’s coming up or already overdue.

These tools were built by the people who build the websites

02 — Website & marketing

Website & Marketing

Fifteen tools for the jobs between a customer hearing about you and calling you.

QR Code Generator

Make a code for your window, truck door, table tent or business card. It is generated on your device, it never expires, and it does not route through a tracking service that can switch off later.

Print it at least an inch wide, keep the white border, and test it with your own phone from where customers will really stand. Dark code on a light background scans best — inverted codes fail on a lot of phones.

UTM Link Builder

Add tags to a link so your analytics can tell you which flyer, post or email actually brought someone in. Use a tagged link everywhere you promote, then stop paying for whatever never shows up.

Quick fill

Your tagged link

 

Keep the words lowercase and consistent. Facebook and facebook count as two different sources in most analytics tools, which is how reports turn into mush.

Business Name Generator

Feed it a word that matters to you and your town, and it builds names in the patterns real local businesses use. Treat the list as a starting point for a conversation, not a verdict.

Before you commit: search the name in Google and on Facebook, check the Alabama Secretary of State business search, and see whether a matching domain is free.

Name ideas — tap to copy

    Business Description Writer

    The same few sentences get asked for over and over: your Google Business Profile, your Facebook about box, the header of your website. Fill in the blanks once and get all three lengths, written plainly rather than stuffed with buzzwords.

    Separate them with commas.

    Fill in the fields and the three versions land here: a one-liner, a Google Business Profile paragraph, and a longer about section.

    Social Media Post Generator

    Staring at an empty post box is why most small business pages go quiet for months. Pick a reason to post, and get three drafts to edit in your own voice and send.

    Posts land here. Change a few words so it sounds like you — a post that sounds like a form letter gets scrolled past.

    Business Hours Generator

    Set your hours once and get clean text for your website, Google Business Profile and Facebook — plus a live status that shows whether you’re open right now.

    Business Name Availability Checklist

    Type the name you’re considering and check it against the places that matter, before you print anything with it on there.

    Progress

    0 / 6

    Checking a box just tracks your progress on this page — it does not check anything for you. Click each link to actually search.

    SEO Snippet Generator

    The title and description Google shows in search results. Both have a hard length limit — go past it and Google truncates it for you, usually badly.

    Titles and descriptions land here, each with a live length check.

    Slug Generator

    Turn a page or post title into the clean, lowercase, hyphenated URL that search engines and humans both prefer.

    UTM Campaign Preset Generator

    One destination and one campaign name, tagged for every channel you actually use, generated all at once and kept consistent with each other.

      Social Media Bio Generator

      Every platform wants the same information in a different length. Fill it in once and get a version sized for each one.

      Instagram, Facebook, LinkedIn, Google and X-sized bios land here.

      Google Business Profile Post Generator

      Google Business Profile posts get seen by people actively searching for you right now. Short, specific and with a clear button beats a wall of text.

      Your post lands here, sized for a Google Business Profile card.

      Call-to-Action Generator

      Button text and ad copy that tells someone exactly what to do next. A vague button gets ignored; a specific one gets clicked.

        Website Content Checklist

        What a small-business site needs before it’s actually ready to launch, not just ready to look at.

        Ready to launch

        0 / 14

        Work through the list — it’s the same one we run through before we flip a client’s site live.

        Need the domain and the hosting sorted?

        Silvea registers your domain, sets up email on it and runs the hosting, so you are not juggling three logins and a renewal notice you forgot about. If you would rather run it yourself, we will point you at the setup we use.

        Ten small tools for the paperwork and quick math that fills the rest of the day.

        PDF Invoice Generator

        A plain, professional invoice as a real PDF — not a screenshot of a spreadsheet. Fill it in, download it, email it. Your business details can be remembered on this device so the next one takes a minute.

        Time Zone Converter

        Line a meeting or call time up across the country before you send the invite, not after someone shows up an hour off.

            Eight tools for moving text and pages between PDF, DOCX, TXT, Markdown and HTML — everything processed on your device.

            Document Converter

            Paste text or upload a file, pick where it needs to end up. Complex formatting, tables and images in the original are not preserved — this moves the words, cleanly.

                05 — Image tools

                Image Tools

                Nine tools for getting a photo ready — sized, compressed, cropped or cleaned up — all processed on your device.

                Image Resizer

                Phone photos are enormous, and a page full of them is why a website crawls on a truck-stop signal. Resize before you upload. Your photo is processed on your device and never sent anywhere.

                Tap to choose a photo, or drag one here

                Around 80 is the sweet spot. Above 90 the file gets much bigger and almost nobody can see the difference.

                Choose a photo and the resized version shows up here with its new file size.

                Image Type Converter

                Switch a photo between JPG, PNG and WebP without changing its dimensions. Browsers cannot write GIF files, so GIF is supported as an input only.

                Tap to choose an image, or drag one here

                Choose an image to preview the conversion.

                Image Compressor

                Same dimensions, smaller file. Good for photos that are already the right size but too heavy to email or upload quickly.

                Tap to choose a photo, or drag one here

                Choose a photo and see the size drop as you move the slider.

                Image Cropper

                Drag the box to move it, drag the corner handle to resize it, then crop. Pick a ratio preset for a square profile photo or a widescreen banner.

                Tap to choose a photo, or drag one here
                Aspect ratio

                Works best on desktop for now — drag with a mouse. On a phone, pinch-crop tools built into your photo app usually work better anyway.

                Rotate & Flip

                Turn a sideways photo right-side up, or mirror it, before it goes anywhere.

                Tap to choose a photo, or drag one here

                Choose a photo to start turning it.

                Image Metadata Remover

                Phone photos carry hidden EXIF data — sometimes including exactly where the photo was taken. This rebuilds the image without any of it.

                Tap to choose a photo, or drag one here

                Choose a photo — the version we hand back has no location or camera data attached.

                Image Background Remover

                Best on a product photo shot against a plain, solid-colour background. It lifts the background by color, not by recognizing objects, so busy or textured backgrounds will not come out clean.

                Tap to choose a photo, or drag one here

                Choose a photo, then remove the background.

                Image ↔ Base64 Converter

                Turn a small image into a text string you can embed directly in code or CSS, or turn that string back into a picture.

                Upload a photo or screenshot and click anywhere on it to pull the exact color — useful for matching a brand color from a logo.

                Favicon Generator

                Upload a square logo and get back every icon size a modern site actually asks for, zipped up together with the HTML tags to drop in your <head>.

                Tap to choose a logo, or drag one here

                A square image works best — anything else gets center-cropped to a square first.

                Social Media Image Resizer

                Crops and resizes to the exact dimensions each platform wants, instead of leaving it to their auto-crop to guess what matters in the frame.

                Tap to choose a photo, or drag one here

                Choose a photo to preview the crop.

                Website Screenshot Tool

                Capture any public page as an image. This is the one tool on this page that is not fully offline — it asks a third-party screenshot service to load the page, since a browser cannot photograph a site it did not open itself.

                Uses the free Microlink.io API. Only public pages work — nothing behind a login.

                The screenshot appears here once it loads.

                Color Palette Generator

                Upload a photo or logo and pull out the colors that actually appear in it — a fast way to find a palette that already matches your branding.

                  07 — FAQ

                  Questions

                  Are these tools really free?

                  Yes. No account, no email, no trial that turns into a bill. Silvea Technologies builds websites, email and hosting for small businesses — these tools are how a lot of people meet us first.

                  Do my numbers, photos or invoices get uploaded?

                  No. Everything on this page runs inside your browser. Your invoice details and photos never leave your device, and nothing is stored on a server. You can turn off your internet after the page loads and the tools still work.

                  Can I use what I make here for my business?

                  Yes. QR codes, invoices, links, names and images you create are yours, commercially, with no attribution and no license.

                  How do I get more Google reviews?

                  Ask every happy customer the same day the job finishes, while your name is still fresh, and make it one tap with a direct review link. Never offer a discount or a freebie in exchange — Google strips those reviews and it can cost you the listing.

                  Are the calculators tax or legal advice?

                  No. They are arithmetic to help you think, not advice. Rates, fees and tax rules change and your situation is specific — run anything important past your accountant.

                  Will my QR code stop working later?

                  Not from our side. The code encodes your link directly instead of pointing at a redirect service we host, so there is nothing for us to switch off. It works as long as the page it points to exists.

                  Can you build one of these for my own site?

                  Yes — calculators, quote tools and booking flows are the sort of thing that turns a brochure site into something that brings work in. Tell us what you have in mind.
