Elterngeld Calculation in Google Sheets

This macro calculates the parental allowance (Elterngeld) in Germany within a Google spreadsheet. We used it for our planning and the results match well with the official calculator (Elterngeldrechner).

Note: You are not paid exactly these amounts, but the average parental allowance over all months of entitlement. This is also what is displayed by the official calculator.

This macro comes without warranty. Please report any errors!

Setup

1. Create a new spreadsheet.
2. Click on Extensions -> Apps Script. A new tab is opening.
3. Copy the elterngeld.gs snippet below into the project and hit save.
4. Go back to the spreadsheet.

Usage

Take a look at this example sheet

Explanation:

• Column A is the age of your child in months
• Column B is the type of Elterngeld:
  • mama: Maternity Benefit (Mutterschaftsleistung)
  • basis: Basis-Elterngeld
  • plus: Elterngeld Plus
  • bonus: Partnerschaftsbonus
• Column C is your income in that month. In this example the person takes care of the baby for 6 months full-time and then starts working part-time.
• Cell H1 is your pre-birth income
• Column D is the calculated parental allowance. Double-click in cell D2 and type: =elterngeld(B2, $H$1, C2). Pull down the cell for all months.

function elterngeld(type, income_pre_birth, income) {
    // Source: https://familienportal.de/familienportal/familienleistungen/elterngeld/faq
    if (type == "mama") {
        // Maternity Benefit, 100% of pre-birth income
        return income_pre_birth;
    } else if (type == "basis") {
        // 65% of income difference, but 1800€ max.
        return Math.min(1800, 0.65 * (income_pre_birth - income));
    } else if (type == "plus" || type == "bonus") {
        // 65% of income difference, but max. half of the maximum basic parental allowance
        var eg_basic_max = Math.min(1800, 0.65 * income_pre_birth);
        return Math.min(
          0.5 * eg_basic_max,
          0.65 * (income_pre_birth - income)
        );
    } else {
        return 0;
    }
}

there is typo,

instead of typ it should be type in the code.

Thanks for your message! Actually it wasn't a typo, but the German word for type (typ), which is a valid argument name. But obviously the German words are confusing, so I translated everything to English 🙂
