The Formula Applied
The calculator converts 6 months to 0.5 years, then applies I = P × r × t. Each percentage point of rate is worth $25 over six months on $5,000 — so the difference between a 5% and a 6% deal is exactly $25 on this term.
Months vs. Days
If your term is given in days instead, the calculator divides by 365. For example, $5,000 at 6% for 180 days earns $5,000 × 0.06 × (180/365) = $147.95 — slightly less than the 6-month figure, because 180 days is a bit short of half a year.

Frequently Asked Questions
Is 6 months always half a year in these calculations?
Yes — the calculator divides months by 12, so 6 months is exactly 0.5 years. Day-based terms divide by 365 instead, which can differ slightly.
How much would $5,000 earn in 6 months in a high-yield savings account?
At around 4.5% APY, roughly $112 — but savings accounts compound, so the exact figure is marginally higher than the simple-interest result.
What if I borrow $5,000 for 6 months at 18%?
You would owe $5,000 × 0.18 × 0.5 = $450 in interest, repaying $5,450 in total under simple interest.
Does the calculator handle principal amounts under $1,000?
Yes. Any positive amount works — the formula scales linearly, so $500 at 6% for 6 months earns exactly $15.
