Interest Island

Four island projects, your own cash and a loan offer for each. Borrow nothing, half or most: borrowing makes good years better and bad years worse. Pick the best usual year that still survives a bad one.

Borrowing and risk

How to play

Read. Each plan shows the cash you end the year with in a usual, good and bad year.
Choose. 250 for the best plan that survives a bad year, 100 for another safe one, 0 if it can sink you.
Three levels. Beginner, Intermediate or Expert, picked before you play: the content and the clock change, and each level keeps its own best score.
Coins. Example numbers in plain fictional coins, made up for the game. Not financial advice.

Quick tips

Check the bad year. A plan that ends below zero in a bad year means owing more than you have.
Rate vs return. Borrowing only helps when the usual return beats the loan rate.
