INTRODUCING

Advanced Calculator

A form-driven calculator for Elementor: quotes, mortgages or pricing worked out live from what the visitor types in.

PLAINSUM

Numbers you can check yourself

A small independent site of free calculators. No signup, no email capture, and the assumptions behind every answer written underneath it.

Future Value
RUNNING COSTS

What a trip actually costs in fuel

Distance, consumption and the price at the pump. Worth doing before you agree a delivery rate, or when somebody argues the train is dearer.

Invalid input. Please check the values and try again.
Trip Cost
DEBT

The single rate you are actually paying

It opens empty on purpose. Put in your own six balances and the rate on each, and it returns the blended rate twice, with the mortgage counted and without, because that comparison is what decides whether consolidating helps.

Invalid input. Please check your balances and rates.
Blended Rate (With Mortgage)
Blended Rate (Without Mortgage)
Debt consolidation

Bring the numbers, we will do the sums

It opens on a typical set of balances so you can see the shape of the answer before you type anything. Replace them with yours, mail the result to yourself, and take both rates to the appointment.

The worksheet does the rest, before anyone opens a spreadsheet.

What you need in front of you

The latest statement for each debt, and the rate printed on it. Nothing else — no credit pull, no login, no account.

Check the balances and rates - one of them is not a number.

Total balance carried

On a broker's landing page

Sitting above the booking form, so the first call starts with a number instead of a question.

Inside a member portal

Behind the login, beside balances the member is already looking at that morning.

At the end of a debt guide

The article explains why a blended rate matters. This is where the reader tries it on their own numbers.

Paying in every month, for years

Set a contribution, a frequency, a rate you believe in and a number of years. It separates what you put in from what the market added, which is the honest way to look at it.

Invalid input. Please check your allocation amounts.
Total Portfolio Value
Total Principal Invested
Total Investment Gains

Will the rent cover the mortgage?

Rent in, mortgage and running costs out, and the cap rate against the purchase price. If the monthly figure is negative the deal only works if the property gains value.

Invalid input. Please verify property price metrics.
Monthly Net Cash Flow
Capitalization Rate (Cap Rate)

How much a customer is worth

Revenue per user and monthly churn give lifetime value. Set that against what you paid to win them: under three to one, growth is expensive.

Invalid input. Verify churn variables stay above zero.
LTV : CAC Efficiency Ratio
Customer Lifetime Value (LTV)

Before you commit the ad budget

Budget divided by click cost gives traffic, conversion rate gives orders, order value gives revenue. Move one number and watch the return follow.

Invalid input. CPC inputs must remain positive.

Return on Ad Spend (ROAS)

What the car costs per month

Price plus tax, less deposit and part-exchange, spread over the term. The monthly figure is the one the showroom quotes. The total interest is the one it does not.

Invalid input. Check down payment or loan terms.
Estimated Monthly Payment
Total Amount Financed

The lowest hourly rate that works

Take-home target plus expenses, divided by the hours you can genuinely bill. Most people find the answer is higher than what they currently charge.

Invalid input. Total tracking parameters must clear zero limits.

Quantity breaks, and the free-shipping line

Unit price and quantity give the subtotal, the volume tier takes its cut, and it shows how far the basket still is from qualifying for free delivery.

Invalid quantity or price mapping.

NUTRITION

A daily calorie number you can live with

Weight, height, age and how much you actually move. It gives the resting figure, the maintenance figure, and a target that takes weight off slowly rather than fast.

Please make sure your metrics are realistically adjusted.

Basal Metabolic Rate (BMR)

PRICING

Margin, before you agree a discount

Revenue and cost, and the percentage left over. Twenty percent off the price is almost never twenty percent off the margin, and this is the quickest way to see by how much.

Invalid input. Please check the values and try again.
Profit Margin
WORKED EXAMPLE

Sell at 240 against a cost of 165 and the margin is 31 percent. Discount that to 216 and the cost has not moved, so the margin falls to 24 percent. The price dropped a tenth; the profit dropped almost a quarter.

BORROWING

What a loan costs over its life

Amount, rate and term. It returns the monthly payment, which is the number people compare in the showroom or on the phone. Multiply it by the number of months to see what the borrowing actually costs.

READ THE TERM, NOT THE PAYMENT

Stretching the same borrowing over a longer term always lowers the monthly figure. Run it at four years, then at six: the payment falls by less than you expect, and you make twenty-four more of them.

Invalid input. Please check the values and try again.
Monthly Payment
MOST USED

The tax one everybody looks for

Net amount, tax rate, total. It is the most-used page on the site by a distance, which says something about how often people need it and how rarely they trust the mental arithmetic.

Invalid input. Please check the values and try again.

FAQ
Frequently asked

Advanced Calculator

Straight answers about what this one does, where it fits in a real build, and what it costs you to ship.

Still stuck?

Read the documentation for this one, or write to us — a human answers inside a business day.

Can I build a calculator without writing any formula?

Yes — twelve ready-made calculators are built in. The Advanced Calculator widget in Sky Addons for Elementor ships presets for price quotes, loan repayments, BMI, tips, savings growth, percentages, discounts, tax, profit margin, ROI, BMR and fuel cost, each with editable starting values, plus a Custom option.

How do formulas work in the Elementor calculator widget?

Give each field a short Formula Key and write an ordinary expression using those names, such as price * qty * (1 – discount / 100). The Sky Addons Advanced Calculator evaluates it with Formula.js, so spreadsheet functions including SUM, IF, ROUND, PMT and POWER work exactly as they do in a spreadsheet cell.

Can one calculator show more than one result?

Yes, and they can build on each other. Each result row in the Sky Addons Advanced Calculator has its own label, formula and Result Key, rows compute from top to bottom, and a later formula can call an earlier result by name — so a subtotal can feed a tax line which then feeds the total.

Can the calculator update live as the visitor types?

Yes. The Calculate On control offers Submit, which waits for the button, or Change, which recalculates on every keystroke and every dropdown choice. Either way the Sky Addons Advanced Calculator rolls the figure up to its new value with a count-up animation you can switch off.

What kinds of input fields can a calculator use?

Six types: number, text, select, radio, hidden and disabled. In the Sky Addons Advanced Calculator each field also takes a column width from full down to a fifth, and a hidden field is the neat way to carry a constant such as a tax rate into the formula without showing it.

Can the calculator result be formatted as currency or as words?

Both. Every result row in the Sky Addons Advanced Calculator takes a prefix, a suffix, a decimal count and a thousands-separator switch for money, and switching the Format to Text lets a formula return a quoted phrase instead — the way a BMI figure becomes a named category.

Can visitors email the calculation result to themselves?

Yes. Turning on the email option in the Sky Addons Advanced Calculator adds a button under the result that reveals an email field, and the message can go to the visitor, to a site address, or to both. Subject line, success message and error message are all editable.

Do I need Elementor Pro or a form plugin for this calculator?

Neither. The Advanced Calculator is a Sky Addons Pro widget running on free Elementor, and it is not a form add-on — it does not need Contact Form 7, WPForms or Elementor Pro forms to work. No third-party calculator service or API key is involved either.

Does the calculator layout stack properly on mobile?

Yes. Column widths set per field apply to desktop, and every field in the Sky Addons Advanced Calculator falls back to full width on a phone, so a two-column quote form becomes one readable column at 390px rather than a pair of squeezed inputs sitting side by side.

What happens when someone enters an invalid value?

The calculator shows your own Error Text rather than printing a broken figure, and the message clears itself after five seconds so the form does not stay blocked. The wording is a plain text field in the Sky Addons Advanced Calculator, so it can be written in any language.

Are the numbers visitors enter stored on my site?

No. The Sky Addons Advanced Calculator works out every result in the browser and saves nothing to the WordPress database — there is no entries list to manage or purge. The only thing that ever leaves the page is the optional result email, and only when a visitor asks for it.

Can I style each result box differently?

Yes. Every result row in the Sky Addons Advanced Calculator carries its own background, border, radius, padding and separate colour and typography for its label and its number, and a Primary switch promotes one result to hero size. A single Accent Colour drives the button, the figure and the input focus ring together.
