When Nemin.io Is the Better Choice
- You need an answer now. On a client call or in a meeting, opening a Nemin.io tool is faster than building a sheet.
- You aren’t sure of the formula. Margin versus markup, or how to gross up a rate for tax, are easy to get wrong. Nemin.io has them built in.
- You want a market-style starting price. The Website Cost, SEO Cost and Social Media Pricing tools give a ballpark using built-in U.S. prices, which a blank spreadsheet can’t do.
- You’re on your phone. A simple web form is easier to use on a small screen than a spreadsheet.
When a Spreadsheet Is the Better Choice
- You need a record. Nemin.io doesn’t save or export results.
- You compare many scenarios. A sheet shows ten versions side by side; on Nemin.io you re-enter the inputs each time.
- You use your own rate card. If your prices differ from Nemin.io’s built-in assumptions, a sheet lets you use your real numbers.
- You work outside the U.S. A spreadsheet can use any currency and local tax rules.
- You share with a team or client. A shared sheet keeps everyone on the same numbers.
Spreadsheet Formulas for Every Nemin.io Calculator
If you like a Nemin.io result and want to keep or extend it, these Excel and Google Sheets formulas reproduce the same maths. Put each input in the cell shown, and enter percentages as decimals (for example 0.25 for 25%).
ROI Calculator
Revenue in B1, total cost in B2:
=(B1-B2)/B2 gives ROI. Format the cell as a percentage.
Profit Margin Calculator
Revenue in B1, cost in B2:
Margin: =(B1-B2)/B1. Markup: =(B1-B2)/B2.
Break-Even Calculator
Fixed costs in B1, price per unit in B2, variable cost per unit in B3:
=ROUNDUP(B1/(B2-B3),0) gives break-even units, rounded up like Nemin.io does.
Freelancer Hourly Rate Calculator
Target income in B1, expenses in B2, billable hours per week in B3, working weeks in B4, tax buffer in B5:
=(B1+B2)/(1-B5)/(B3*B4)
Agency Retainer Calculator
Hours in B1, hourly rate in B2, software costs in B3, desired margin in B4:
=(B1*B2+B3)/(1-B4)
Google Ads Budget Calculator
Leads in B1, conversion rate in B2, average CPC in B3, management fee in B4:
=B1/B2*B3+B4 gives the total monthly budget.
Email Campaign ROI Calculator
List size in B1, open rate in B2, click rate in B3, conversion rate in B4, average order value in B5, campaign cost in B6:
Revenue: =B1*B2*B3*B4*B5. ROI: =(B1*B2*B3*B4*B5-B6)/B6.
As in Nemin.io, the click rate here applies to opens, so use your click-to-open rate.
Website Cost, SEO Cost and Social Media Pricing
These three Nemin.io tools are not just formulas. They depend on built-in prices, such as $180 per website page or $30 per target keyword. To copy them into a spreadsheet you need your own rate card. Our Nemin.io marketing budget guide and Nemin.io pricing guide list every built-in amount, which you can use as a template and then replace with your own prices.
Word Counter
Google Docs and Microsoft Word already have word counts, so a spreadsheet isn’t the right tool here. The Nemin.io Word Counter adds a reading-time estimate at 200 words per minute, which you can reproduce by dividing your word count by 200 and rounding up.
Example: The Same Calculation Both Ways
Say a small online shop has $6,000 in monthly fixed costs, sells a product for $50 and spends $20 per unit on stock and shipping.
- On Nemin.io: open the Break-Even Calculator, enter 6000, 50 and 20, and click Calculate. The result is 200 units, $10,000 in break-even revenue and a $30 contribution per unit. It takes about 15 seconds.
- In a spreadsheet: type 6000, 50 and 20 into B1 to B3, then
=ROUNDUP(B1/(B2-B3),0)in B4. The answer is the same 200 units. It takes a minute or two the first time, but now you can copy the column and test a $45 or $55 price next to it.
The answer is identical. The difference is speed now versus flexibility later.
The Best Approach: Use Both
For most freelancers and small businesses, the two work best together:
- Explore with Nemin.io. Get a fast first answer and a feel for which inputs matter most.
- Record in a spreadsheet. Copy the inputs and results into a sheet, using the formulas above, so you have a saved version.
- Refine in the spreadsheet. Swap in your real prices and currency, and compare scenarios side by side.
- Double-check with Nemin.io. Run the same inputs through the tool to catch formula typos in your sheet.
