What this calculator does
Sharing something in a ratio means giving each person a number of "parts". With a ratio of 5 : 3 : 2 there are 10 parts in total. This tool works out the size of one part and then each share, so you never have to do the arithmetic by hand.
How to use it
- Type the total you want to share, such as 500.
- Type the ratio parts, at least two and up to four.
- Press Split it and read the table of shares.
The method
- Add the parts of the ratio.
- Divide the total by that sum to find the value of one part.
- Multiply each ratio part by the value of one part.
5 + 3 + 2 = 10 ⇒ 500 ÷ 10 = 50 per part
Shares: 5 × 50 = 250, 3 × 50 = 150, 2 × 50 = 100
Examples you can try
| Total | Ratio | Shares |
|---|---|---|
| 500 | 5 : 3 : 2 | 250, 150, 100 |
| 1,200 | 1 : 2 : 3 | 200, 400, 600 |
| 90 | 4 : 5 | 40, 50 |
| 75 | 2 : 3 | 30, 45 |
| 1,000 | 7 : 3 | 700, 300 |
Where people use it
- Money: split rent, business profit or an inheritance in agreed proportions.
- Cooking: divide a batch of dough or a sauce between pans.
- Teams and time: assign 8 hours of work between three people in a 3 : 2 : 3 split.
- Mixing: for paint or concrete, the mixing ratio calculator is built for this.
Tips
- The order matters. In 5 : 3 the first share is the larger one.
- Shares always add back up to your total. That is a quick check.
- Money may need rounding to cents. The tool shows up to six decimals so you can round the way you prefer.

Frequently asked questions
How do you split an amount by a ratio?
Add the ratio parts, divide the total by that sum to get one part, then multiply each ratio part by it.
How do I split 500 in the ratio 5:3:2?
The parts add to 10, so one part is 50. The shares are 250, 150 and 100.
Can I split into more than two shares?
Yes, up to four shares in this calculator.
Do the shares always add up to the total?
