How much interest will I pay on a short term federal payment plan?

[devinlbr]

If I owe on my taxes this year and want to set up a payment plan, how much interest will I pay in 180 days?

no one can give you an exact figure since interest starts accruing on 4/16. interest rates change every quarter. 4/1, 7/1,10/1

the current rate is 7% (1/1-3/31) so as an estimate use 3.5% times the amount you owe.
