Service Pricing Calculator

Enter your assumptions, calculate, then review the supporting rows and warnings before using the result.

Mode

Price inputs
Package and retainer

Enter your values and choose Calculate to show the result.

Formula and assumptions

Primary formula

Target-margin price = (cost / (1 - target margin) + fixed fee) / (1 - percentage fee). Cost-plus price = (cost x (1 + markup) + fixed fee) / (1 - percentage fee). Discounts are applied after the selected base method.

Variables

Base cost is the delivery cost. Markup and margin are shown separately. Fixed and percentage fees can represent platform or processing costs.

Worked example

Example: a 100 base cost with 40% target margin gives 166.67 before fees. With a 5 fixed fee and 3% percentage fee, price is about 176.98 before discount.

Visual method model

Inputs

Entered values, period labels, unit settings and optional row details.

Formula

Deterministic Decimal.js arithmetic with zero-denominator validation.

Output

Headline result, supporting metrics, warnings, visual bars and optional CSV rows.

What the Service Pricing Calculator does

Service Pricing Calculator focuses on service price planning from cost, margin and fee assumptions. It uses only values entered on the page and keeps the arithmetic deterministic.

The output is a planning estimate. It should be checked against source systems, contracts, tax rules, payroll rules or inventory operations before decisions are finalized.

How to use the Service Pricing Calculator

Enter values from the same period or operating scenario, choose the relevant mode when a mode is offered, then calculate.

Use the detailed rows when you want a blended result across campaigns, employees, plans, cost lines or inventory snapshots.

Formula

Target-margin price = (cost / (1 - target margin) + fixed fee) / (1 - percentage fee). Cost-plus price = (cost x (1 + markup) + fixed fee) / (1 - percentage fee). Discounts are applied after the selected base method.

Variable definitions

Base cost is the delivery cost. Markup and margin are shown separately. Fixed and percentage fees can represent platform or processing costs.

Calculation steps

NexaCalc validates required denominators, converts units when needed, runs Decimal.js arithmetic, then rounds only for display, tables and CSV export.

  • Check required inputs and reject zero denominators.
  • Convert units or periods into the formula basis.
  • Calculate the headline result and supporting comparisons.
  • Show warnings, CSV rows and visual bars without hiding assumptions.

Assumptions

These assumptions are visible because business calculators are only as useful as the definitions behind the inputs.

  • Target margin must be below 100%.
  • Percentage fee is modeled as a percentage of the charged price.
  • Discounts are applied after fee-aware price in this model.

Reverse calculations and planning outputs

Where practical, the page also solves adjacent planning questions from the same input set.

  • Markup price
  • Margin price
  • Fee-aware price
  • Discounted price
  • Package price
  • Retainer estimate
  • Required clients from monthly revenue target

Worked example

Example: a 100 base cost with 40% target margin gives 166.67 before fees. With a 5 fixed fee and 3% percentage fee, price is about 176.98 before discount.

Result interpretation

The headline result answers the main calculation question. The secondary cards show unit economics, cost drivers, comparison values or operational thresholds.

Visual bars are neutral context. They are not industry benchmarks and do not label a business as healthy or unhealthy.

Common mistakes

Most mistakes come from mixing definitions, periods or numerator and denominator sources.

  • Using markup when target margin is intended.
  • Forgetting payment processing or platform fees.
  • Pricing a package without multiplying the unit economics.

Limitations

This calculator does not connect to accounting, payroll, ad, inventory, banking or subscription systems.

  • Does not validate market demand.
  • Does not model taxes or payment timing.
  • Does not account for negotiation or scope changes.

Compliance and accounting note

The calculator is not a substitute for tax, payroll, legal, accounting, procurement or revenue-recognition review. Use the result as a transparent worksheet, not as a filing or compliance position.

Rounding and exports

The engine calculates with Decimal.js and rounds display values after calculation. CSV exports escape spreadsheet-sensitive text before download.

Privacy

Inputs are calculated in the browser session. NexaCalc does not require an account or store these Business Phase 3 calculator values.

Disclaimer

Calculated rates and prices are planning estimates and do not guarantee market demand, project cost or profit.

Frequently asked questions

What is the Service Pricing Calculator?

It is a NexaCalc calculator for service price planning from cost, margin and fee assumptions.

Does the calculator fetch live business data?

No. It uses values entered manually and does not connect to ad platforms, payroll systems, inventory software, accounting tools or banks.

Can I use different periods together?

Only when the period difference is intentional and clearly adjusted. Otherwise, keep cost, revenue, demand, time and quantity inputs on the same basis.

Why do some results show unavailable?

A reverse calculation needs a valid target or denominator. When that value is missing or zero, NexaCalc labels the output instead of returning infinity.

Does the currency selector convert money?

No. Currency changes display formatting only. Enter all money amounts in the same currency.

Can I export the result?

Yes. Calculators with row details can export CSV, and every page supports copy, print and share actions.

Is this accounting, tax, payroll or legal advice?

No. The calculator is a deterministic worksheet for general business planning.

Can this replace platform or system reports?

No. Use source-system reports for official analytics, payroll, inventory, tax, accounting and subscription records.

How are formulas versioned?

This page uses Business Phase 3 method set v1.0.0: acquisition, inventory, payroll, pricing, project and subscription formulas. The method note shows the last reviewed date.
