Questions about the should my spouse work?
Does a second income always help financially?
Not always. After taxes and the costs of working — especially childcare — a second salary can net far less than it appears, and occasionally costs more than it brings in.
Why use a combined tax rate?
A second income often stacks on top of the first, so it is taxed at your higher marginal rate. Using that rate captures the real tax bite on those extra dollars.
Should I decide on money alone?
No — career progression, benefits, retirement contributions and personal fulfilment matter too. This calculator covers the dollars so you can weigh them against the rest.
