This study investigates how partners’ money management strategies are associated with the experience of financial disagreements among older couples (60–80 years old). Money management is a broad concept, and this study operationalizes whether the partners pool all money, the partners pool some money, one partner manages the money (and gives a share to the other partner for personal spending), or the partners keep all money separate. The data comprise a subsample from the Swedish Generations and Gender Survey from 2012 to 2013. The descriptive statistics show that 11% of older couples experience financial disagreements and that there is a large variation in how couples manage their money. Contrary to our expectations, logistic regression analyses further indicate that couples who pool all money are less likely to have financial disagreements than couples who either keep all money separate or adopt a lower degree of pooling. Whether some or all money is kept separate does not seem to be important for the likelihood of financial disagreements, as all these couples are more likely to experience disagreements. Among couples with financial hardship, partial pooling and keeping money separate are associated with a higher likelihood of financial disagreements than pooling all money. In conclusion, the greater probability of financial disagreements among couples who do not pool their earnings calls for greater awareness of the potential consequences of various money management contexts among individuals, couples, decision-makers and practitioners. In the worst cases, couples may have poor financial wellbeing.
