School fees are not an emergency. They arrive on roughly the same dates every year and for roughly the same amount, which makes them the easiest large expense to plan for and — for reasons that have nothing to do with arithmetic — the one that most often gets handled with a last-minute loan.
Work backwards from the date
If the fee is ₦420,000 a year across three terms and the first is due in September, you have twelve months and you need ₦35,000 a month. Set a Target Savings plan for the term amount with the term date, and the money moves on its own.
Target Savings pays 16% a year, so the ₦420,000 you needed costs you about ₦385,000 of your own money over the year. Saving early is not only less stressful, it is cheaper.
