The Department of Finance (DOF) has an online tax calculator that lets you easily calculate your monthly income-tax deduction. The tax calculator also serves to promote the Tax Reform for Acceleration and Inclusion (TRAIN) law by showing how much smaller your personal income tax is under it compared to the old tax system.
I did some sample calculations for a single, private employee with no dependents, and the results are as follows (all figures in pesos).
| Monthly Salary | Old Income Tax | New Income Tax |
| 21,000 | 2,924 | 0 |
| 22,000 | 3,171 | 37 |
| 23,000 | 3,417 | 234 |
| 24,000 | 3,664 | 431 |
| 25,000 | 3,910 | 628 |
| 30,000 | 5,339 | 1,615 |
| 35,000 | 6,818 | 2,626 |
| 40,000 | 8,297 | 3,859 |
| 45,000 | 9,797 | 5,109 |
| 50,000 | 11,356 | 6,359 |
| 55,000 | 12,956 | 7,609 |
| 60,000 | 14,556 | 8,859 |
| 65,000 | 16,156 | 10,109 |

ABS-CBN News also offers a similar calculator, the Pinoy Tax Reform Calculator.
If you want a detailed computation you can use the online withholding tax calculator provided by the Bureau of Internal Revenue (BIR), the BIR Tax Calculator, which includes additional inputs, such as allowances, night differential, holiday pay, and more.
Note that SSS, PhilHealth and Pag-IBIG are pretax deductions, which means that they are computed and deducted first before the income tax is calculated.
