Standby Pay Calculator: $390.00 for 120 Hours, 2 Callouts
On the defaults — 120 standby hours at $2.00 an hour plus 2 callouts at $75.00 — you earn $390.00 of standby pay: $240.00 standby plus $150.00 callout. This is the STANDBY-ROTATION version — a full 120-hour rotation priced hour by hour — the on-call-pay-calculator page is the SHORTER-SHIFT version — 40 standby hours at $3.00 with the same callout model; the call-back-pay-calculator page is the CALL-BACK version — a minimum guarantee plus a multiplier on return-to-work hours; and the how-to-calculate-standby-pay guide is the METHOD version — the same 120 hours and 2 callouts worked step by step.
What does $390.00 of standby pay mean?
It means that being on standby for 120 hours, paid at $2.00 an hour, is worth $240.00, and being called out twice at $75.00 a callout is worth another $150.00, for $390.00 in total. The split is the whole story in miniature — the standby line is the slow earner and the callout line is the fast one: one extra callout is worth $75.00, which is what 37.5 standby hours pay, so a quiet rotation and a busy rotation with the same hours can pay very differently. The part people get wrong is treating standby pay as if it were pay for working: it is pay for being available, and the callout fee is the separate pay for actually going in — a rotation with no callouts still earns the $240.00 standby line, and a rotation with callouts earns both lines, never one instead of the other.
Three things to check before you trust the number
Is the $2.00 rate for every standby hour, or only some? Some contracts pay standby only outside normal hours, or pay a lower rate for daytime standby and a higher rate overnight, and the 240-hour branch pays $630.00 against the $390.00 headline, so doubling the hours at the same rate adds exactly $240.00. If your contract pays only night standby at $2.00 and day standby at a lower rate, a single-rate calculation overstates the standby line. Check which hours the rate covers before multiplying it by the full 120.
Does a callout replace standby pay for those hours? No — in this model the two lines stack: the callout fee is paid on top of the standby hours, not instead of them, and the 0-callout branch pays $240.00 against the $390.00 headline, which is the standby line standing alone. Some contracts pay callout hours at your normal hourly rate instead of a flat fee, or pay the greater of the fee and the hours worked — if yours does, price the callout line on that rule, because a 3-hour callout at $25.00 an hour is $75.00, exactly the flat fee here, but a 1-hour callout at the same rate is only $25.00.
Are callouts counted per trip out or per call received? A night with two separate callouts to two different sites is two callouts here, worth $150.00, while a single incident that generates two phone calls is usually one callout, worth $75.00 — and the 4-callout branch pays $540.00 against the $390.00 headline, so each disputed callout is worth $75.00. Count incidents, not phone calls, unless your contract says otherwise, and log the time of each callout so a disputed one can be checked.
Worked example
On the defaults: 120 standby hours, $2.00 an hour, 2 callouts, $75.00 a callout.
- Standby pay: 120 × $2.00 is $240.00.
- Callout pay: 2 × $75.00 is $150.00.
- Total standby pay: $240.00 + $150.00 is $390.00.
And the other way: the standby rate behind $390.00 is $2.00 an hour, the callouts behind $390.00 are 2 callouts, and the callout pay behind $390.00 is $75.00 a callout.
Every branch, checked
- 60 standby hours, same rate and callouts: 60 standby hours, same rate and callouts: $270.00 standby pay.
- 240 standby hours, same rate and callouts: 240 standby hours, same rate and callouts: $630.00 standby pay.
- $3.00 standby rate, 120 hours: $3.00 standby rate, 120 hours: $510.00 standby pay.
- 0 callouts, 120 hours: 0 callouts, 120 hours: $240.00 standby pay.
- 4 callouts, 120 hours: 4 callouts, 120 hours: $540.00 standby pay.
- $100.00 callout pay, 120 hours: $100.00 callout pay, 120 hours: $440.00 standby pay.
The reverses, worked backwards
- Standby rate behind $390.00: $2.00 an hour — at $2.00 an hour the figures are $390.00 standby pay.; at the lower neighbor the figures are $330.00 standby pay.; at the upper neighbor the figures are $450.00 standby pay..
- Callouts behind $390.00: 2 callouts — at 2 callouts the figures are $390.00 standby pay.; at the lower neighbor the figures are $315.00 standby pay.; at the upper neighbor the figures are $465.00 standby pay..
- Callout pay behind $390.00: $75.00 a callout — at $75.00 a callout the figures are $390.00 standby pay.; at the lower neighbor the figures are $340.00 standby pay.; at the upper neighbor the figures are $440.00 standby pay..
What the defaults assume
The defaults are 120 standby hours, a $2.00 standby rate, 2 callouts and a $75.00 callout fee, so the headline is a worker holding a full standby rotation — 120 hours is five 24-hour days — with two callouts during it. The model is two multiplications and an addition: standby pay is hours times the standby rate, callout pay is callouts times the callout fee, and total pay is the sum of the two lines. The rate reverse is checked at $0.50 either side, because $0.50 on 120 hours is $60.00; the callouts reverse is checked at 1 either side, because one callout is $75.00; the callout-fee reverse is checked at $25.00 either side, because $25.00 on 2 callouts is $50.00. The model does not include callout hours paid at an hourly rate, minimum callout guarantees, standby rates that vary by time of day, or overtime on callout hours — split the rotation at any rule change.

Who uses this
- A nurse or technician on a standby rota — 120 hours at $2.00 plus 2 callouts at $75.00 are $390.00, with the standby line and the callout line shown separately so a short payslip is easy to spot.
- A payroll clerk verifying a standby claim — the reverses recover the standby rate, the callout count or the callout fee behind any quoted figure.
- An IT support worker comparing rotas — the branches show whether an extra callout or a higher standby rate moves the total more on their own rotation pattern.
- Anyone negotiating standby terms — the 60-hour and 240-hour branches price a shorter or longer rotation on the same model, so a rate offer can be compared like for like.
Accuracy & limitations
Figures are the model’s own arithmetic on the numbers you type, computed from unrounded values and displayed rounded HALF_UP to 2dp. The main limitation is the contract terms, not the arithmetic: standby rates, callout fees, minimum guarantees and whether callout hours are paid hourly vary by employer, and this page pays one standby rate and one flat callout fee on every hour and callout. This page is a calculation tool, not payroll or employment advice.

Frequently asked questions
What is standby pay?
Standby pay is pay for being available to be called out, usually at a lower rate than working time: hours times the standby rate, plus callouts times the callout fee. On the defaults, 120 hours at $2.00 plus 2 callouts at $75.00 earn $390.00.
Do I still get standby pay if I am never called out?
Yes: the standby line is paid for the availability itself, not for the callouts. The 0-callout branch pays $240.00 — the full standby line with no callout line on top — so a quiet rotation still earns $240.00 on these defaults.
Is the callout fee instead of standby pay for those hours?
No: the two lines stack. The standby hours are paid at the standby rate whether or not a callout happens, and each callout adds its flat fee on top. A rotation with 2 callouts earns $240.00 plus $150.00, not $150.00 instead of $240.00.
What if callouts are paid by the hour instead of a flat fee?
Then this page’s flat-fee line does not fit your contract: price the callout line as callout hours times your hourly rate, and add it to the standby line. A 3-hour callout at $25.00 an hour is $75.00, the same as the flat fee here, but shorter callouts pay less under an hourly rule.
How is standby pay different from on-call pay?
It is the same idea under a different name: both pay a rate for availability plus a fee per callout. This page’s defaults are a 120-hour rotation at $2.00 an hour, while the on-call-pay-calculator page uses a 40-hour shift at $3.00 — same model, different rotation length, so use whichever matches your rota.
What if my standby rate changes overnight?
Split the rotation: price the daytime hours at the daytime rate and the night hours at the night rate, then add the two standby lines and the callout line. A single rate applied to mixed-rate hours overstates or understates the standby line by the rate gap times the mispriced hours.
