What are rounding rules?
Rounding rules are the final step in the repricing calculation. After the repricer figures out the ideal price based on your competition settings, price floor, and safety nets, it applies rounding to produce a clean, psychologically appealing final price.
Ever noticed that most prices on marketplaces end in .99 or .95? That's not random. Pricing psychology shows that prices ending in certain digits feel lower to buyers. Rounding rules let you take advantage of that automatically.
Available rounding options
No rounding
The price is left exactly as calculated. If the repricer calculates $14.27, it stays at $14.27. Use this if you want maximum precision and don't care about the ending digits.
End in .99
The price is rounded to the nearest value ending in .99. For example:
- $14.27 becomes $14.99
- $25.10 becomes $24.99
- $30.50 becomes $30.99
This is the most popular choice. The ".99" ending is deeply ingrained in how consumers perceive prices, and it works well across nearly every product category.
End in .95
The price is rounded to the nearest value ending in .95. For example:
- $14.27 becomes $14.95
- $25.10 becomes $24.95
A subtle alternative to .99 that some sellers prefer for slightly more premium-feeling positioning.
Whole unit
The price is rounded to the nearest whole dollar (or equivalent in your currency). For example:
- $14.27 becomes $14.00
- $14.60 becomes $15.00
Clean, round numbers can feel more trustworthy and are sometimes preferred for higher-priced items or storefront channels where the aesthetic matters.
Custom step
Round the price to the nearest custom increment you define. You enter a step value between $0.01 and $0.99 (for example, $0.25). The repricer then rounds the price to the nearest multiple of that step.
For example, with a $0.25 step:
- $14.27 becomes $14.25
- $14.40 becomes $14.50
- $14.80 becomes $14.75
This gives you fine-grained control over price endings when the standard options don't fit your needs.
Rounding and your price floor
Rounding always respects your price floor. If rounding would push the price below your floor, the repricer rounds up instead of down. Your margins are always protected, no matter what rounding option you pick.
If you're using a cost-based price floor, rounding may cause your actual ROI or margin to differ slightly from your target. For example, your target might be 30% ROI, but after rounding to .99 the actual ROI could end up at 31.2%. This is expected and generally works in your favor.
When to change rounding
Most sellers set their rounding option once and leave it. "End in .99" is a safe default for the vast majority of products. If you sell premium or luxury items, "Whole unit" gives a cleaner look. And if you're competing in very tight penny-level price wars, "No rounding" might give you a slight edge.
Where this fits in the strategy wizard
Rounding is step 5 of 6 in the strategy creation wizard. It comes right after safety nets and before the preview step, so you can see exactly how your prices will look with rounding applied before you save.
