How much are the fare increases?

We know that the fares were raised. We know that it was meant to be a fairer system. We know that 3 out of 4 commuters would benefit from the fare hike and 1 out of 4 would have to pay more. How much more and how much less? We also know that the transport companies would lose $88m in revenue. Really? Let’s look at some numbers. I am using what I know to extrapolate the impact on all the commuters. A senior citizen will save 15c if he travels a short distance of 4/5 stations, (68-53). If he travels longer distance, he would have to pay 18c more(86-68). Before the changes, a senior citizen pays 68c for maybe 24 stations. With the new changes, the transport company would even out the reduction in the first 4/5 stations from commuters who travel the next 4/5 stations. Subsequently the rest of the journey or more than 10 stations will be pure additional profits. Give away 15c for 4/5 stations and collect 18c from the next 4/5 stations is already a profit. The rest of the journey collects 18c. Not bad a formula. How could they lose $88m? And the same principle is applicable to students and normal fare commuters. The percentage increases could be much more in the normal fare category. When you collect more and give out less, I think the profit is enormous rather than losing $88m. I stand to be corrected on the exact numbers as I am just extrapolating from the fares of senior citizens. SMRT are cordially invited to provide the exact numbers here.
