Where to keep money for a goal

For goals under three years, a money market fund is the usual choice: you can withdraw in two to three days and yields are well above a savings account. Interest is taxed at 15%, which this calculator already accounts for. For longer goals, a mix of Treasury bonds or a SACCO can earn more.

Frequently asked questions

How much should I save each month?

A common rule is 20% of take-home pay, with the first goal being an emergency fund of three to six months of expenses.

What return should I assume?

Use the current yield of the money market fund you plan to use, minus about one percentage point to stay conservative.
