Tax Refund Advance Trap
Tax Refund Advance Calculator — True Cost Trap
What this calculator does
Refund advances often charge a percentage of your refund. This calculator shows the true cost after accounting for the small time value of waiting for the IRS.
The math, with a worked example
Advance fee = refund × fee percentage. Time value = refund × HYSA APR ÷ 365 × 14 days. True cost = advance fee − time value. A $2,500 refund with a 10% advance fee costs $250. Waiting 14 days in a 4.5% savings account earns only $4.32, so the true cost is $245.68.
Why this matters
A refund advance sells you your own money for a fee: $250 to get a $2,500 refund 2 weeks early, when waiting would cost you about $4 of lost savings interest. The 'advance' prices 2 weeks of patience at roughly 60 times its market value.
Methodology and transparency
True cost = refund × advance fee % minus the time value of waiting (refund × savings APR ÷ 365 × 14 days). The 14-day window models the IRS's typical e-file-with-direct-deposit turnaround — paper filing stretches it, which narrows the gap slightly but rarely enough to matter against a double-digit fee. 'No-fee' advances price the cost into tax-prep fees instead; count those too. Everything runs in your browser; no data is sent or stored.

Common questions
Why wait for the IRS?
Direct deposit is usually fast and free. Advances prey on impatience.
Are all tax prep fees bad?
Not all, but refund advances and high preparation fees can eat a large chunk of your refund.
