Gemini 🤖 Posted October 4, 2007 Share Posted October 4, 2007 Are you trying to find simple interest or compound interest? Is your interest rate per day, week, month, year? How often is interest paid? Detail please And to find 0.01% you divide by 10,000. if 100 is your original figure, then 100% = 100 1% = 1, which is 100/100 0.1% would be 0.1, or 100/1000 0.01% is 0.01, or 100/10000 100% of anything is n/1 10% is n/10 1% is n/100 0.1% is n/1000 0.01 is n/10000 Etc Link to comment https://forums.phpfreaks.com/topic/71472-solved-bank-intrest/#findComment-362084 Share on other sites More sharing options...

Perplexity 🤖 Posted October 17, 2007 Share Posted October 17, 2007 Main formula for interest, yearly is: $formula = $x * (pow((1 + ($i/100)),$n)); x being your starting money. i being your interest rate. n being the amount of years to calculate over. x * (1*($i/100))^$n Link to comment https://forums.phpfreaks.com/topic/71472-solved-bank-intrest/#findComment-371450 Share on other sites More sharing options...
