Six months of parental leave on a 4,500 monthly salary with 1,200 statutory pay leaves a 19,800 shortfall — the foregone earnings net of leave pay. Plan for this gap before the leave starts and explore phased returns or shared leave to reduce it.
A worked example
Try the defaults: monthly salary of 4,500, leave months of 6, monthly leave pay of 1,200. The tool returns 19,800.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.
What moves the number most
The result responds to Monthly Salary, Leave Months, and Monthly Leave Pay. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.
The formula behind this
Shortfall equals salary minus leave pay times months. Tax savings on the foregone salary aren't netted off — assume conservative gross figures for buffer planning. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
What the headline number hides
Gross pay, net pay, and what actually lands in your account can differ by thousands depending on tax code, benefits, pension contributions, and student loan deductions. This tool isolates one piece of that picture — always pair it with a take-home calculator for the full view.
What this doesn't capture
Tax bands, pension contributions, student-loan deductions, and benefits-in-kind sit outside this calculation. The figure is the headline; your actual position depends on local tax rules and personal circumstances. Pair with a dedicated take-home calculator for the full picture.
Total earnings shortfall during this leave is the figure shown above.
