About compound interest
The difference between a rate and a return is compounding frequency. Interest earned daily and reinvested grows faster than the same nominal rate paid once a year, and the gap widens as the rate rises — at 8% the difference over five years is real but modest, at 80% it is enormous. This shows the compounded result against plain simple interest so the contribution of compounding alone is separated from the rate itself.
Common questions
How do I calculate compound interest on a yield?
Enter a principal, a rate, a compounding frequency and a term. This applies the standard compound formula so you can see how often reinvestment is assumed — daily versus monthly changes the ending balance.
Does crypto yield always compound automatically?
No. Some positions rebase, some pay a reward token you must sell and reinvest, and some do nothing until you harvest. The calculator models a frequency you choose; it does not claim your pool compounds that way.
Why does more frequent compounding look better?
Because interest earns interest sooner in the formula. In practice, harvesting more often can cost network fees that erase the theoretical edge — which is why the auto-compound planner exists beside this tool.
