Saving Throw Roller 5e
This free saving throw roller is for D&D 5e players and game masters who need a d20 plus a save bonus against a Difficulty Class. Pick the ability, type the bonus you actually use, set the DC, and choose advantage or disadvantage if something grants it. The chance shown is the chance that your total meets or beats that DC.
Pick an ability, set your save bonus and the DC, then tap to roll.
Chance that dexterity +3 meets DC 15: 45.0% (total vs DC, before any 2024 natural 20 or natural 1 rule)
How to use the saving throw roller
Pick the ability. Saving throws are tied to Strength, Dexterity, Constitution, Intelligence, Wisdom or Charisma. The label does not change the math. It just names the roll so the table can see which save you made.
Enter the full save bonus and the DC. Add your ability modifier, proficiency if you are proficient in that save, and any other bonus the table agrees on. Then type the DC from the spell, trap or monster feature. Press the big die or Roll save.
Switch on advantage or disadvantage when you have it. Two d20s are rolled and the higher or lower face is kept, then the bonus is added once. Both faces stay visible. For a longer walkthrough of those two states, use the advantage roller.
Need typed notation such as 1d20+5, or a mix of other dice? Use the main DnD dice roller. For a general twenty sided page, open the d20 roller.
How saving throws work
When a spell, hazard or special attack tells you to make a saving throw, you roll a d20 and add the matching save bonus. If the total equals or exceeds the DC, you succeed. A success might mean you take no damage, you take half damage, or you avoid a condition, depending on the effect.
The bonus is not looked up for you. A Dexterity save with a +2 Dexterity modifier and proficiency at +3 is a +5, which you type yourself. That keeps this page a roller, not a character builder.
Death saving throws are a different track. They use a plain d20, succeed on a 10 or higher, and treat a natural 1 as two failures and a natural 20 as 1 hit point back. Mark those on the death saves tracker.
2014 totals vs 2024 natural 20 and natural 1
Under the 2014 rules (SRD 5.1), a normal saving throw compares the total to the DC. Rolling a 20 with a low bonus can still fail a very high DC, and rolling a 1 with a high bonus can still succeed a low DC.
Under the 2024 rules (SRD 5.2.1), attack rolls, ability checks and saving throws are D20 Tests. A natural 20 succeeds and a natural 1 fails, even if the total would have said otherwise. This tool always compares the total to the DC and shows the matching chance. If your table uses the 2024 rule, treat a natural 20 as a success and a natural 1 as a failure after you see the face.
Odds against a DC
Each face of a fair d20 is 5%. If you need 11 or higher on the die after your bonus is applied, you succeed 50% of the time. Advantage raises a middling target more than it raises a very easy or very hard one. The chance line above the FAQ updates as you change the bonus, the DC or the mode. For other pools, use the dice probability calculator.
If you succeed on a Dexterity save against something like Fireball, the effect often deals half damage. Roll that damage on roll 8d6 or another damage page, then use the halved total it shows.
Saving throw roller FAQ
Is this saving throw roller free?
Yes. It is free, with no ads and no sign up. Open the page on any device and roll.
How does a saving throw work in 5e?
You roll a d20 and add your save bonus for that ability, which is the ability modifier plus proficiency if you are proficient, plus any other bonuses that apply. If the total meets or beats the DC, you succeed.
Do I add proficiency automatically?
No. Type the full bonus you use at the table, including proficiency and any item or feature bonus. This page does not look up class proficiencies, so it stays a roller rather than a character sheet.
Does a natural 20 or a natural 1 change a save?
Under the 2014 rules (SRD 5.1), a saving throw succeeds or fails based on the total against the DC. A 20 or a 1 is just a high or low number, except on a death saving throw. Under the 2024 rules (SRD 5.2.1), a natural 20 succeeds and a natural 1 fails on a D20 Test, which includes saving throws.
Is a death saving throw the same thing?
No. A death saving throw is a plain d20 with no modifier and its own success, failure, natural 1 and natural 20 rules. Mark those on the death saves tracker.
