How To Calculate Double Time Pay
A single overtime multiplier prices a simple week. A week with daily double time, weekly overtime and a holiday needs each band priced separately before the total means anything.
Quick Answer
weekly pay = straight hours x rate + OT hours x rate x 1.5 + double time hours x rate x 2
- R
- Base hourly rate
- h_r
- Straight-time hours, paid at the base rate
- h_1
- Overtime hours, paid at one and a half times the base rate
- h_2
- Double-time hours, paid at twice the base rate
35 straight hours at £24 are £840. Two overtime hours at 1.5x add £72, one double-time hour at 2.0x adds £48, and the week pays £960 for 38 hours, an effective £25.26 an hour.
What Is Double Time Pay?
Pay bands are the rule that hours worked beyond a threshold are priced higher than the first hours of the week. Straight time, overtime and double time are the three bands most schedules use.
The bands are bands, not a single uplift applied to the last hour. Each hour belongs to exactly one band, and the weekly pay is the sum of each band separately rather than one total multiplied by one number.
Overtime at one and a half times is the standard uplift in most jurisdictions once a weekly threshold is passed. The multiplier applies to the base rate, not to a rate that already includes another uplift.
Double time is charged at twice the base rate and is usually triggered by a daily threshold rather than a weekly one. Hours beyond a set number in a single day attract it, even when the week is short.
Some systems add a seventh consecutive day and some charge double time only past a higher daily threshold. The bands are defined by local rules, which is why the hours have to be entered per band.
Holidays and special days often carry their own premium, and that premium is usually quoted as a multiplier of the base rate. A 2.0x holiday rate and a 1.5x overtime rate are two separate bands.
A single-multiplier calculation fails as soon as more than one band is present. Multiplying the whole week by one average produces a number that does not correspond to any actual payment rule.
The effective hourly rate is the weekly pay divided by the total hours worked. It is higher than the base rate whenever any premium hours are present, and it is the figure that tells you what the week was really worth per hour.
That effective rate falls as straight-time hours are added without premium hours. A 50-hour week at 1.5x pays more in total than a 40-hour week but less per hour worked.
The share of pay coming from premium hours is the cleanest measure of how much the schedule depends on overtime. A week where a fifth of the pay comes from bands above straight time is not the same as one where it does not.
Annualising the weekly figure assumes the week repeats. Multiplying by fifty-two overstates a full-time annual figure because paid leave and unpaid gaps break the pattern, and understates it if the week is a busy one.
Paid leave is normally paid at the straight-time rate, so the annual figure from a heavy premium week is an upper bound rather than an average. Many payroll systems compute the two separately.
The bands are entered as hours, not as totals. Splitting 47 hours into 35 straight, 11 overtime and 1 double time requires knowing which threshold each hour passed, which is a scheduling fact rather than an arithmetic one.
This calculator prices three bands plus a holiday band, reports the weekly total, the effective hourly rate, the annual figure and the share of pay coming from premium hours.
Formula
pay = h_r x R + h_1 x R x 1.5 + h_2 x R x 2 + h_h x R x m_h
Each band is priced separately against the base rate and the four results are added. No band is uplifted on top of another, so the multipliers are all measured from the same base.
| Symbol | Meaning | Unit | Notes |
|---|---|---|---|
| R | Base rate | currency | The hourly rate for straight time. |
| h_r | Straight hours | hours | Hours paid at the base rate. |
| h_1 | Overtime hours | hours | Hours paid at one and a half times the base. |

How To Calculate Double Time Pay
- 1
Split the hours into bands
Count the straight-time hours, the overtime hours, the double-time hours and any holiday hours separately. The split comes from which threshold each hour passed, not from an average.
- 2
Price the straight-time band
Straight hours times the base rate. This band is never uplifted, so the multiplier is exactly one.
- 3
Price the lifted bands
Multiply the overtime hours by one and a half times the rate, the double-time hours by twice the rate, and any holiday hours by the holiday rate you have entered.
- 4
Add the bands and find the effective rate
The four results add to the weekly pay. Dividing by every hour worked, premium hours included, gives the effective rate the week actually paid.
- 5
Read the premium share and the annual figure
The share of pay from lifted bands shows the dependence on premium hours, and fifty-two times the weekly total gives a rough annual figure assuming the week repeats.

| Step | Calculation | Result |
|---|---|---|
| Straight-time pay | 35 x £24 | 840 |
| Overtime pay at 1.5x | 2 x £24 x 1.5 | 72 |
| Double-time pay at 2.0x | 1 x £24 x 2 | 48 |
| Weekly pay | £840 + £72 + £48 | 960 |
| Total hours worked | 35 + 2 + 1 | 38 |
| Effective hourly rate | £960 / 38 | 25.26 |
Result: Thirty-five straight hours pay £840, two overtime hours add £72 and one double-time hour adds £48, so the week pays £960 for 38 hours. That is an effective £25.26 an hour against a £24 base, and £49,920 over 52 identical weeks.
Example 2: A holiday week with a 2.5x premium

- Overtime hours
- 6
- Double-time hours
- 0
- Holiday hours

| Step | Calculation | Result |
|---|---|---|
| Straight-time pay | 32 x £30 | 960 |
| Overtime pay at 1.5x | 6 x £30 x 1.5 | 270 |
| Holiday pay at 2.5x | 8 x £30 x 2.5 | 600 |
| Weekly pay | £960 + £270 + £600 | 1830 |
| Total hours worked | 32 + 6 + 8 | 46 |
| Effective hourly rate | £1,830 / 46 | 39.78 |
Result: Thirty-two straight hours pay £960, six overtime hours add £270 and eight holiday hours at 2.5x add £600, giving £1,830 for 46 hours. The effective rate is £39.78 an hour, and premium hours supply £870 of the £1,830, a little over 47%.

Common Mistakes
Applying one multiplier to the whole week
Each hour belongs to one band and each band has its own multiplier. Multiplying a mixed week by a single average produces a figure that no payment rule agrees with.
Uplifting an already uplifted rate
Double time is twice the base rate, not one and a half times the overtime rate. Chaining the multipliers inflates the double-time band by half.
Using the base rate for holiday hours
Holiday hours normally carry their own premium, and the premium is quoted from the base rate. Forgetting the band understates the week by the whole holiday uplift.
Mixing a daily and a weekly threshold
Double time usually comes from a daily threshold while overtime comes from a weekly one. Counting the same hour in both bands double-pays it.
Dividing the weekly pay by the base rate
The effective rate divides by every hour worked. Using the base rate as the divisor understates the week whenever premium hours are present.
Annualising a heavy premium week
Fifty-two times an unusual week overstates the year, because paid leave is normally paid at straight time. The annual figure is an upper bound unless the week really repeats.
Treating the threshold as the same in every jurisdiction
Weekly and daily thresholds, and the multipliers above them, differ by place and sometimes by industry. The hours have to be entered against the rules that actually apply.
FAQ
What is the difference between overtime and double time?
Overtime is usually one and a half times the base rate and is triggered by a weekly threshold. Double time is twice the base rate and is normally triggered by a daily threshold, so it can apply in a short week.
How do I work out a week with three pay bands?
Price each band separately against the base rate and add the three results. No band is uplifted on top of another, so every multiplier is measured from the same base.
Is double time 2x or 1.5x the overtime rate?
Twice the base rate. Applying one and a half times the overtime rate instead would give three times the base, which is not what any standard schedule pays.
What is the effective hourly rate?
The weekly pay divided by every hour worked, including premium hours. It is above the base rate whenever any uplift hours are present, and it falls as straight-time hours are added.
Do holiday hours count towards overtime?
They normally count as hours worked, but the holiday rate replaces the ordinary rate for those hours. Whether they also count towards a weekly threshold depends on the local rules.
Should I annualise my weekly overtime pay?
Only as a rough guide. Fifty-two times a heavy premium week overstates the year because paid leave is paid at straight time and because unusual weeks do not repeat.
