When to use this
You're in salary negotiations and you have a take-home figure in mind ("KES 80k net per month"), but the offer is in gross terms. Type your target net here, get the gross to ask for. Or you're a business owner sizing up an offer for a new hire.
Trick #1: bump pension to lower your gross-target
Voluntary pension contributions up to KES 30,000/month are deducted before PAYE. If you contribute 10k/month to pension, you don't need as high a gross to hit the same net because you're shifting cash from PAYE to your own retirement corpus. Plug it in above and watch the required gross drop.
Trick #2: insurance relief stacks on top
Life, education, and health premiums get 15% relief, capped at KES 5,000/month relief (KES 60k/year). Adding 5,000 of premium reduces PAYE by 750. Small but free money.
