Quick answer: Oklahoma is a relatively low-cost probate state. The executor commission is a statutory 5/4/2.5% scale that works out to about 2.5% ($12,600 on a $500,000 estate), attorney fees often mirror it, and court fees are about $200. There's no state estate or inheritance tax. Get your own figure with the Oklahoma probate cost calculator.
The executor commission — statutory scale
Under 58 O.S. § 527(A), the commission is a sliding scale on the estate accounted for:
| Portion of the estate | Rate |
|---|---|
| First $1,000 | 5% |
| Next $5,000 (to $6,000) | 4% |
| Above $6,000 | 2.5% |
Attorney fees & the tax picture
Attorney fees aren't fixed by statute but often mirror the same 5/4/2.5% schedule, or are billed hourly — all court-approved. So on a mid-sized estate the commission and attorney fee are similar figures.
Worked total examples
| Estate value | Commission | Attorney (scale) | Court + misc | Approx. total |
|---|---|---|---|---|
| $100,000 | $2,600 | $2,600 | $449 | ≈ $5,649 |
| $500,000 | $12,600 | $12,600 | $449 | ≈ $25,649 |
| $1,000,000 | $25,100 | $25,100 | $449 | ≈ $50,649 |
Court + misc = ~$204 filing + $125 publication + $120 copies. Attorney fee shown at the statutory scale; hourly billing may differ. If the executor waives the commission, subtract that column. Run your own numbers in the calculator.
