Finance
Simple and compound interest, installments, credit comparison, returns, inflation and bill splitting, with assumptions stated.
A financial number without the assumption behind it cannot support a decision. Here the rate, the period and the compounding method sit next to the result, and simple and compound interest stay separate because they are not the same account: with simple interest the rate always applies to the original amount, with compound interest it applies to the accumulated balance. The estimates compare scenarios and do not replace the bank's formal offer, which includes fees and insurance.

1 calculatorsFrequently asked questions
Can simple and compound interest give the same result?
Only in the first period. From the second on, compound interest grows on interest already earned: 1,000 at 10% a month returns 1,200 in two months with simple interest and 1,210 with compound.
Can I use it to compare loans?
Yes, as a scenario comparison with the same rate and term. The official offer may include fees and insurance that change the final cost.
