Everyday money calculators, formulas made plain
Four small calculators answer the questions that come up at the bank, the pay slip, and the shopping cart: what do I really earn, when can I afford it, where does my money go, and what should I set aside. Each one shows its formula and a worked example, so the answer never feels like magic.
