Overdrafts are expensive borrowing. Arranged overdraft typically 35-40% APR — higher than most credit cards. 500 average balance × 200 days × 40% = 110/year just in interest. Plus any monthly fees.
Run it with sensible defaults
Using average overdraft balance of 500, days in overdraft of 200, annual fees of 50, overdraft apr of 40%, the calculation works out to 159.59. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Average Overdraft Balance, Days in Overdraft, Annual Fees, and Overdraft APR — do not pull with equal force. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.
How the math works
Interest = balance × rate × (days/365). Plus annual fees. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".
Why payoff plans work
Debt feels overwhelming when it's an abstract total. Break it into a payoff date and a monthly figure and the problem becomes finite — you can see the finish line. That visibility is what this tool provides, and for many people it's the difference between dithering and acting.
What this doesn't capture
Real payoff journeys include missed payments, fee changes, balance transfers, and promotional rates that reset. The calculation assumes a steady plan; reality is rarely that clean. Use the figure as the best-case plan against which actual progress gets measured.
Overdraft produces annual cost based on the inputs provided.
