Enter hours only after applying your supplied rule
Regular hours and the two overtime tiers are already classified inputs. The calculator does not move hours into a tier, apply a weekly or daily threshold, or determine that overtime is owed.
Each overtime multiplier is interpreted as the total multiple for that tier, including base pay. An entered 1.5 therefore means 1.5 times the base rate, not straight time plus another 1.5.
| Input | Calculation role | Independent check |
|---|---|---|
| Base hourly rate | Rate used for regular and both overtime tiers | Confirm the pay basis required by your supplied rule. |
| Regular hours | Paid once at the base rate | Confirm which hours remain regular. |
| Tier 1 hours and multiplier | First pre-classified overtime amount | Confirm both the hours and total-pay multiplier. |
| Tier 2 hours and multiplier | Second pre-classified overtime amount | Use zero hours when the second tier does not apply. |
Separate eligibility, rule translation and arithmetic
Eligibility and classification come first: identify the worker coverage, exemptions, workday or workweek basis, hours included in the pay basis, and the threshold or tier that applies under the governing local rule or arrangement. Wage101 does not decide any of those questions.
Only after the applicable source, effective date, units and tier assignments are confirmed should the pre-classified hours and total-pay multipliers be entered here. A correct calculation under an inapplicable rule is still not an entitlement answer.
| Stage | Evidence or owner | Stop condition |
|---|---|---|
| Eligibility and classification | Current applicable local authority or governing arrangement | Worker coverage, exemption or governing rule is unresolved |
| Rule translation | Recorded source, effective date, period, threshold and multiplier meaning | Units, date or total-versus-premium interpretation is ambiguous |
| Arithmetic | Overtime Pay Using Your Rule after hours are pre-classified | Hours cannot be assigned to one tier without making a legal assumption |
Calculate the default two-tier scenario using your rule
The default fixture uses a 25 hourly base rate, 40 regular hours, eight tier-1 hours at 1.5 times and two tier-2 hours at 2 times. These are example inputs, not universal thresholds or multipliers.
| Output | Calculation | Result | Interpretation |
|---|---|---|---|
| Regular pay | 25 × 40 | 1,000 | Base-rate pay for entered regular hours. |
| Tier 1 pay | 25 × 8 × 1.5 | 300 | Pay for the first pre-classified overtime tier. |
| Tier 2 pay | 25 × 2 × 2 | 100 | Pay for the second pre-classified overtime tier. |
| Overtime pay | 300 + 100 | 400 | Total pay for both overtime tiers, including base pay. |
| Overtime premium | 400 − (25 × 10) | 150 | Amount above straight-time pay for the overtime hours. |
| Gross under entered rule | 1,000 + 400 | 1,400 | Regular and overtime pay combined. |
| Average hourly rate | 1,400 ÷ 50 | 28/hour | Gross divided by all 50 entered hours. |
Review the rule and any below-base warning
- Confirm the threshold and classification outside the calculator.
- Confirm that each multiplier is a total-pay multiplier.
- Enter each hour in only one category.
- Investigate any active tier with a multiplier below 1; the calculator allows it but flags the result.
- Verify eligibility, exemptions, awards, contracts, payroll and tax independently.
How the Overtime Pay Using Your Rule Calculator calculation works
grossPay = regularPay + overtimePay
- grossPay
- Gross pay under entered rule
- regularPay
- The regular Pay
- overtimePay
- Overtime pay
The calculator and article use this relationship consistently; the article does not reimplement the calculation.
overtimePay = tier1Pay + tier2Pay
- overtimePay
- Overtime pay
- tier1Pay
- The tier1 Pay
- tier2Pay
- The tier2 Pay
The calculator and article use this relationship consistently; the article does not reimplement the calculation.
overtimePremium = overtimePay − baseHourlyRate × (tier1Hours + tier2Hours)
- overtimePremium
- Overtime premium over straight time

- baseHourlyRate
- Base hourly rate
- tier1Hours
- Tier 1 overtime hours

Worked example: Overtime Pay Using Your Rule Calculator
The calculator normalizes the inputs above, applies Gross pay, and returns the outputs below. The displayed result is therefore reproducible in the linked calculator.
| Measure | Result | Interpretation |
|---|---|---|
| Gross pay under entered rule | 1,400 currency units/period | Regular pay plus both entered overtime-tier amounts. |
| Overtime pay | 400 currency units/period | Sum of pay calculated for both entered overtime tiers. |
| Overtime premium over straight time | 150 currency units/period | Overtime pay less base-rate pay for the same overtime hours. |
| Total hours | 50 hours/period | Regular plus both overtime-tier hours. |
| Average hourly rate | 28 currency units/hour | Gross pay under the entered rule divided by total hours. |
Interpret the result and test Tier 1 multiplier
- Gross pay under entered rule: 1,400 currency units/period. Regular pay plus both entered overtime-tier amounts.
- Overtime pay: 400 currency units/period. Sum of pay calculated for both entered overtime tiers.
- Overtime premium over straight time: 150 currency units/period. Overtime pay less base-rate pay for the same overtime hours.
- Total hours: 50 hours/period. Regular plus both overtime-tier hours.
- Average hourly rate: 28 currency units/hour. Gross pay under the entered rule divided by total hours.
| Result | Baseline | Changed-input scenario | How to read it |
|---|---|---|---|
| Gross pay under entered rule | 1,400 currency units/period | 1,430 currency units/period | Regular pay plus both entered overtime-tier amounts. |
| Overtime pay | 400 currency units/period | 430 currency units/period | Sum of pay calculated for both entered overtime tiers. |
| Overtime premium over straight time | 150 currency units/period | 180 currency units/period | Overtime pay less base-rate pay for the same overtime hours. |
| Total hours | 50 hours/period | 50 hours/period | Regular plus both overtime-tier hours. |
| Average hourly rate | 28 currency units/hour | 28.60 currency units/hour | Gross pay under the entered rule divided by total hours. |
