Calculate a FAAB bid for fantasy football waivers as a percentage of your original or remaining budget, rounded to whole dollars, with an optional reserve.
FAAB Bid Formula and Method
100 × 15% = 15
Choose the fraction of a budget that you are willing to bid and whether that fraction refers to the original season allocation or the remaining balance. The planner converts that choice to whole budget units and caps it at the balance left after your reserve.
How to Use This Calculator
Enter your original season budget and remaining balance, choose the percentage basis, and enter your bid percentage. Optionally enter a reserve to keep after bidding. Select Calculate to view the whole-unit bid and calculation details.
Worked Example
With the example inputs in the table, the result is 15 budget units. Choose your own percentage and reserve; the tool converts them into an affordable whole-unit bid.
Bid = min(floor(percentage amount), remaining budget − reserve)
Input and Example Guide
| Input or category | Example or weight | Entry guidance |
|---|---|---|
| Original season FAAB budget (whole budget units) | 100 | Use a whole count in the stated unit. |
| Remaining FAAB balance (whole budget units) | 65 | Use a whole count in the stated unit. |
| Balance to reserve after this bid (whole budget units) | 20 | Use a whole count in the stated unit. |
| Apply your chosen percentage to | Original season budget | Choose the convention that applies to your record. |
| Chosen bid percentage (%) | 15 | Use the stated unit; retain available precision. |
Interpreting the Result
A reserve is a deliberate amount you keep available after the bid, so it cannot exceed the current balance. The same percentage can produce very different bids on the original and remaining bases. The result is an affordability plan; it does not estimate competitor bids or decide a player’s value.
This is a budget planner, not a player valuation or a prediction of the winning bid. League minimums, tie priorities and zero-dollar bid rules are separate.
Assumptions and Common Input Errors
Choose your own percentage and reserve; the tool converts them into an affordable whole-unit bid. Use credited records rather than mixing estimates with final totals. Required fields start empty; a blank optional reserve means zero.
