More than a calculator result
UtilityPilot helps you copy useful calculation outputs into SOPs, spreadsheets, CRM notes, Slack, Notion, client emails and team checklists, so repeat tasks are faster and less manual.
How to choose
Which calculator do you need?
Counting working days?
Use the Business Days Calculator if you just need Mon–Fri between two dates. For UK bank holidays, use UK Working Days. For other countries, pick from the country list below.
Invoice or payment dates?
Use the Invoice Due Date Calculator to find when Net 30/60/90 terms expire. Use the Real Due Date Calculator to adjust for weekends and public holidays.
VAT, GST or sales tax?
Use the VAT Calculator for any rate (20%, 5%, zero, or custom). For UK-specific HMRC rates use UK VAT Calculator. For Europe use the EU VAT Calculator. For US, use US Sales Tax.
SLA or deadline tracking?
Use the SLA Deadline Calculator for business-hours deadlines (e.g. 8-hour response windows). Use Real Due Date for day-level deadlines that must skip non-working days. Not sure which to use? Try the Business Deadline Checker.
Shipping and freight?
Use the CBM Calculator to get shipping volume for LCL sea freight quotes. Use the Shipping Deadline Calculator to find the real delivery date from a dispatch date and transit time.
Profit margin or pricing?
Use the Margin Calculator to check gross profit % from cost and sell price. Use Markup Calculator to set a sell price from cost plus a markup percentage.
Importing goods?
Use the Freight Chargeable Weight Calculator to find the air freight billing weight before getting a quote. Then use the Landed Cost Calculator to build the full cost per unit including duty, VAT/GST and broker fees.
Payroll or time tracking?
Use the Time Card Calculator for weekly hours, overtime and gross pay from daily start/end times. Use the Work Hours Calculator for shift totals and the Decimal Hours Calculator for payroll entry.
Evaluating an investment?
Use the ROI Calculator to measure return percentage and investment multiple. Then use the Payback Period Calculator to find how long until the investment recovers its cost. Use the Working Capital Calculator to check you have the liquidity to fund it.
Decision guide
Which calculator should I use?
Built for real work
Designed for business workflows, not one-off calculations
Every calculator on UtilityPilot is built around a step in a real business process — not generic arithmetic. Finance teams use the Invoice Due Date and VAT calculators as part of invoice and AR workflows. Operations managers embed the Business Days and SLA Deadline calculators in SOPs and project checklists. Logistics teams use CBM and Shipping Deadline calculators in freight quote sheets. Payroll administrators use the Decimal Hours and Work Hours calculators in timesheet processing. The results are clear, formulae are shown, and everything is safe to paste into emails, CRM notes, Notion pages, and client templates.
