Estimate what a new business website should cost to build
A free, no-signup calculator suite for US-based businesses and marketers.
Get to Know the Nemin.io Toolkit
Nemin.io brings together the everyday math behind running a business, from setting your rates to sizing an ad budget, in one lightweight browser-based toolkit you can open the moment a number needs checking.
Why Nemin.io Exists
We built Nemin.io on a straightforward belief: the numbers that shape a small business should not sit behind paid software or get buried in tangled spreadsheets. The aim is to turn common pricing, budgeting, and ROI questions into quick, honest estimates that anyone can run in seconds and act on the same day.
What the Toolkit Includes
Every tool here is a purpose-built calculator rather than a generic template. Enter your own figures and each one hands back a clear result you can drop straight into a proposal, a budget review, or a planning conversation with a client.
The collection keeps expanding across the areas where owners lose the most time: pricing services, sizing marketing and ad spend, weighing SEO investment, and forecasting profit margin. Nemin.io asks for nothing to install, no trial to remember to cancel, and no account standing between you and the answer.

Planning NoteA quick word on the numbers: the calculators here are planning aids, not financial guarantees.

Treat each estimate as a well-informed starting point and pair it with your own judgment before you commit to a price or a budget.

What is Nemin.io?
Nemin.io is a free online suite of calculators and planning tools built for people who run and grow businesses. Instead of wrestling with spreadsheets, you plug in a few numbers and get quick, usable figures for pricing, margins, budgets, and return on investment. Everything runs in your browser, so there is nothing to download or install.
Who should use these tools?
The toolkit is aimed at freelancers, agency owners, early-stage founders, marketers, consultants, and small business operators who need fast answers without hiring an analyst. Whether you are setting a project rate, sizing an ad budget, or checking whether a campaign paid off, the calculators fit the day-to-day decisions these roles face. No finance background is required to get value from them.
Are the calculators actually free?
Yes, every tool on Nemin.io is free with no account, subscription, or trial period attached. You will not hit a paywall partway through a calculation or be asked for card details to see your results. The goal is to give small teams and solo operators reliable planning numbers at zero cost.
What kinds of tools can I find here?
The collection spans pricing calculators, profit margin and markup helpers, marketing budget and ad spend planners, ROI estimators, and project quoting tools, among others. Each one focuses on a single, practical question so you can jump straight to what you need. New calculators are added over time to cover more corners of business and marketing planning.
Do the estimates work for US-based planning?
The calculators are designed with US freelancers, agencies, and small businesses in mind, using dollar amounts and assumptions that match how work is priced and budgeted in the States. Keep in mind that every result is a planning estimate meant to guide your thinking, not a substitute for tailored accounting or tax advice. Treat the figures as a solid starting point and confirm specifics with a professional when the stakes are high.
