I copy and paste the proposal from Chris,
"1. The Standard Interest Rate
Interest is paid on regular balances (outputs), on every block, for a period of up to 30 days (288x30 blocks). The rate is 0.0000002384185791015625% (1/2^22). It's compounded every block, so the rate is approximately 2,4 % APR. However, remember there is a maximum of 30 days, so to get that APR, you'd need to log in each month and shuffle the ERC to a new address.
2. Time Lock Bonus
If you lock an amount of ERCs a term deposit, you can also get a bonus on the interest. The bonus is just a multiplier of the interest, so if you locked up 100 ERC for 1 year, you'd expect a return of 5 ERC. (Capital 100% + Interest 2,4% + Term Deposit Bonus 2% until 3%)."
I hope, I gave u the answer u needed.
