Work out what your helper is owed for a pay period — base salary plus pay for any Sundays worked. Free, and nothing is saved or sent anywhere.
Creating an account takes a minute — HAH! then does this every month and keeps the payslips for both of you.
A helper's monthly pay is the agreed base salary, plus pay for any rest days worked. In Singapore, that rest day is usually a Sunday. If your helper works on one instead of taking it off, that day is paid on top of the base salary at the rate the two of you agreed in writing.
Total payable = base salary + (Sundays worked × the agreed Sunday rate)
The rate for a rest day worked should be agreed with your helper before it happens, and written into the employment contract. A common approach is one day's pay — the monthly salary divided by 26. What matters most is that both of you know the number in advance, so a worked Sunday never becomes an argument at the end of the month.
Some helpers have a salary deduction in their first months of employment. If that applies to you, enter the amount actually payable as the base salary — the calculator adds rest-day pay on top of whatever base you enter.
MOM sets the timing, and it is the rule most often broken by accident: salary must be paid no later than 7 days after the end of the salary period, and the salary period itself must not be longer than one month. Paying "at the end of the month, when I get round to it" is how a household drifts into breaching it.
Four more rules worth knowing:
Whatever you pay, keep a written record of it. A payslip each month protects both sides: your helper can see exactly how the figure was reached, and you have a record of what was paid and when. Most salary disagreements come from remembering different things about a Sunday months later — a written record removes the argument entirely.
HAH! does this automatically: your helper plans their Sundays in the app, you approve them, and the payslip is generated for you both at the end of each pay period.
