Employee Net Promoter Score Definition

eNPS (Employee Net Promoter Score) measures employee loyalty and engagement by asking how likely employees are to recommend your company as a place to work. Scores range from 0–10, with 10 being the highest. A score of 75 is considered excellent.

Employee NPS Inputs

- Number of Promoters (score 9–10)
- Number of Passives (score 7–8, optional, not used in calculation)
- Number of Detractors (score 0–6)

eNPS Formula

eNPS = % Promoters − % Detractors
% Promoters = (Number of Promoters ÷ Total Responses) × 100
% Detractors = (Number of Detractors ÷ Total Responses) × 100
Note: Passives are ignored in the calculation

Example of How to Calculate Employee NPS or eNPS

Promoters: 25
Passives: 10
Detractors: 5

Total Responses = 25 + 10 + 5 = 40
% Promoters = 25 ÷ 40 × 100 = 62.5%
% Detractors = 5 ÷ 40 × 100 = 12.5%
eNPS = 62.5 − 12.5 = 50

eNPS Output

eNPS score ranges from -100 to +100. Positive values indicate more promoters than detractors, showing strong engagement.

Headcount Growth Planner

Definition of Headcount Growth

Projects your team’s future size over time based on current headcount and an expected growth rate. Helps you plan staffing and resources with confidence.

How to Use the Headcount Growth Planner

- Enter your current headcount.
- Input the expected growth rate per period (%).
- Enter the number of periods you want to project.
- Click Calculate to see your future headcount.

Headcount Growth Formula

Future Headcount = Current Headcount × (1 + Growth Rate)^Periods
Where:
- Current Headcount = your team’s current number of employees
- Growth Rate = expected growth rate per period (as decimal, e.g., 20% → 0.20)
- Periods = number of periods to project (quarters, months, or years)

Example of How To Calculate Headcount Growth

Current Headcount: 10
Growth Rate: 20% per quarter
Periods: 3

Future Headcount = 10 × (1 + 0.20)^3 = 17 employees

Headcount Growth Output

The tool shows the projected future headcount based on your inputs.

Paid Time Off (PTO) Calculator

About the Paid Time Off Calculator

Calculates how many paid time off (PTO) hours you’ll accumulate over a chosen number of periods, based on your accrual method (per pay period, per hour worked, per month, or per year), starting balance, and an optional cap.

How to Use the PTO Calculator

- Pick your accrual method.
- Enter the accrual rate (e.g., 3.33 hours per pay period).
- Add your current PTO balance.
- If accruing “per hour worked,” enter typical hours per period.
- Choose how many periods to project.
- (Optional) Set a cap if your policy limits maximum PTO.
- Click Calculate.

Paid Time Off Formula

PTO Accrued = Starting Balance + (Accrual Rate × Number of Periods)
If capped: PTO Accrued = min(PTO Accrued, Cap)

Example of How to Calculate Paid Time Off

Accrual Method: Hours per pay period
Accrual Rate: 3.33 hours
Starting Balance: 0 hours
Periods: 26 (bi-weekly for a year)
Cap: 120 hours

Projected PTO = 0 + (3.33 × 26) = 86.58 hours
If PTO balance reaches 120 hours, accrual stops at the cap.

PTO Output

The tool shows the projected PTO balance based on your inputs and optional cap. Note: This assumes no PTO usage; deducting hours will reduce subsequent balances.

Salary Increase Calculator

Definition of Salary Increase

A salary increase is when your pay goes up by a certain percentage or flat amount. To figure out your new salary, you take your old salary and add the increase.

How to Use the Salary Increase Calculator

- Enter your current salary.
- Choose the type of increase: Percent (%) or Flat Amount ($).
- Enter the increase value.
- Click Calculate to see your new salary and the details of the increase.

Salary Increase Formula

New Salary = Current Salary + (Current Salary × Increase% / 100)
Or if flat amount: New Salary = Current Salary + Increase Amount

Example of How to Calculate Salary Increase

Current Salary: $50,000
Increase: 5%
New Salary = 50,000 + (50,000 × 0.05) = 50,000 + 2,500 = 52,500

Salary Increase Output

The tool displays your new salary, the increase amount, and the increase percentage.

Employee Turnover Cost Calculator

Definition of Employee Turnover Cost

Replacing an employee costs more than just their salary. Businesses lose money on recruiting, training, and lost productivity while the position is unfilled or the new hire ramps up.

How to Use The Turnover Cost Calculator

- Enter the recruiting costs for hiring a new employee.
- Enter the training costs associated with onboarding.
- Enter the estimated lost productivity costs during the transition.
- Click Calculate to see the total turnover cost.

Employee Turnover Cost Formula

Turnover Cost = Recruiting Costs + Training Costs + Lost Productivity

Example of How to Calculate Employee Turnover Cost

Recruiting Costs = $5,000
Training Costs = $3,000
Lost Productivity = $8,000
Total Turnover Cost = 5,000 + 3,000 + 8,000 = 16,000
This means losing and replacing one employee could cost $16,000 or more.

Employee Turnover Cost Output

The tool displays the total estimated cost of losing and replacing an employee.

Time Duration Calculator

Definition of Time Duration

The Time Duration Calculator helps you quickly find the difference between a start time and an end time. This is useful for tracking work hours, project timelines, or event scheduling.

Time Duration Formula

Duration = End Time − Start Time

Step-by-Step Example of How to Calculate Time Duration

Step 1: Start = 9:15 AM, End = 1:45 PM
Step 2: Count full hours → 9:15 → 1:15 = 4 hours
Step 3: Count remaining minutes → 1:15 → 1:45 = 30 minutes
Step 4: Add together → 4 hours + 30 minutes = 4 hours 30 minutes

Shortcut Method to Calculate Time Duration

Convert times into minutes since midnight:
9:15 AM = 9 × 60 + 15 = 555 minutes
1:45 PM = 13 × 60 + 45 = 825 minutes
Subtract: 825 − 555 = 270 minutes
Convert to hours and minutes: 270 ÷ 60 = 4 hours, remainder 30 minutes
Result: 4 hours 30 minutes ✅
