Notice Period Calculator — US, Canada & UK Notice Rules
Select a jurisdiction, choose resignation or employer termination, and enter length of service. The calculator returns a statutory baseline where a general rule exists. Contracts, collective agreements, provincial/state law, exceptions, and common-law rights can require something different.
Quick answer: There is no general US federal notice formula for ordinary individual private-sector terminations. Canada's federal labour standards apply only to federally regulated workplaces, while provinces and territories set rules for most other Canadian workers. The UK has statutory minimums for both dismissal and resignation, with contracts able to require longer notice.

If notice is not worked, employers may pay instead. Use the Pay in Lieu of Notice Calculator to estimate the lump-sum equivalent.
How Notice Periods Are Calculated
Notice periods typically scale with length of employment — the longer you've worked for an employer, the more notice is generally required. There are three sources that determine your actual notice entitlement, in order of priority:
- Employment contract: If your contract specifies a notice period, that governs — provided it meets or exceeds the legal minimum. Contracts can require more than the statutory floor but not less.
- Statutory minimums: Employment laws set minimum notice floors that apply regardless of contract. These vary significantly by country and province.
- Reasonable notice (common law): In Canada particularly, courts may award notice beyond the statutory minimum based on factors like seniority, age, and difficulty of finding comparable employment (the Bardal factors).
This calculator uses a simplified statutory-based estimate. Actual entitlement — especially in Canada — is often higher than statutory minimums. Always check your employment contract and consult an attorney for terminations involving significant notice claims.
Notice Period Rules: US, Canada, and UK
United States
For ordinary individual private-sector employment, there is no single federal notice-period formula. Contract terms, collective bargaining agreements, and state law can create obligations. The federal WARN Act is a separate rule for certain covered plant closings and mass layoffs; covered employers generally must give 60 calendar days' advance written notice when WARN's thresholds are met.
Official reference: U.S. Department of Labor — Plant Closings and Layoffs (WARN).
Canada — Federal Labour Standards
The federal rule below applies to employees in federally regulated businesses. It is not a Canada-wide formula for all workplaces. For an employer-initiated individual termination, federal standards currently require:
| Completed service | Federal employer notice / wages in lieu |
|---|---|
| Less than 3 months | No federal statutory minimum under this termination rule |
| 3 months to under 3 years | 2 weeks |
| 3 years | 3 weeks |
| 4 years | 4 weeks |
| 5 years | 5 weeks |
| 6 years | 6 weeks |
| 7 years | 7 weeks |
| 8+ years | 8 weeks maximum |
The federal employer-termination rule does not create an employee-resignation notice formula. If an employee resigns, check the employment contract and the applicable provincial, territorial, or other law.
Official reference: Canada.ca — Termination, layoff or dismissal.
United Kingdom
For employer notice, the statutory minimum is:
- Less than 1 month of service: no statutory minimum under the general dismissal rule
- 1 month to under 2 years: 1 week
- 2 to under 12 years: 1 week for each complete year
- 12 years or more: 12 weeks
For an employee resigning, at least 1 week's notice is required after more than 1 month in the job; the contract can require more. Always compare the statutory minimum with the contract because the longer contractual notice may control.

Pay in Lieu of Notice (PILON)
When a notice entitlement exists, an employer may in some circumstances end employment immediately and provide pay instead of requiring the employee to work the notice period. The amount and included benefits depend on the applicable law and contract.
The Pay in Lieu of Notice Calculator deliberately does not decide how many weeks you are legally owed. It converts a notice period you have already identified into a base-pay estimate using weekly pay × notice weeks.
In the UK, PILON and other notice pay are generally subject to normal tax and National Insurance treatment; the separate £30,000 exemption that may apply to some termination compensation should not be assumed to make PILON tax-free.
Frequently Asked Questions
What does this notice period calculator estimate?
It estimates selected statutory notice baselines using the jurisdiction, who is giving notice, and completed service. It does not override a longer contract term or calculate common-law, provincial, state, collective-agreement, or case-specific rights.
How much notice does a US employer have to give?
There is no general federal notice formula for ordinary individual private-sector terminations. Contracts, state law, or collective agreements may create notice rights. The federal WARN Act is separate and can require 60 days' notice for certain covered plant closings and mass layoffs.
How much notice does a federally regulated Canadian employer have to give?
Under current federal labour standards, an employer generally owes 2 weeks after at least 3 months but less than 3 years of service. After 3 years, the minimum is 1 week per completed year, up to 8 weeks. Provincial and territorial rules apply to most non-federal workplaces and can differ.
How much notice does a UK employer have to give?
The statutory minimum is generally 1 week for service from 1 month to under 2 years, 1 week per complete year from 2 to under 12 years, and 12 weeks for 12 years or more. A contract can provide a longer period.
How much notice does a UK employee have to give when resigning?
After more than 1 month in the job, the statutory minimum is at least 1 week. The employment contract may require more notice.
Is notice the same as severance?
No. Notice or pay in lieu replaces a notice period that should have been worked or provided. Severance is a separate form of separation compensation and may or may not be required depending on the law, contract, plan, or collective agreement.
What is pay in lieu of notice?
Pay in lieu of notice is payment made instead of having the employee work some or all of an applicable notice period. Use the Pay in Lieu of Notice Calculator after you have identified the notice weeks that apply.
Is this calculator legally binding?
No. It is an informational statutory-baseline tool. Notice rights can depend on the contract, workplace jurisdiction, reason for termination, collective agreement, and other exceptions.
