Why the same R100 buys less later in the month

On this tariff, Midvaal sells electricity in blocks that start again on the first of every month. The first 50 kWh each month cost R2.51 a unit, VAT included, and the price goes up in steps after that, to R5.14 a unit above 600 kWh.

So R100 buys 39.9 kWh at the start of the month, but only 22.6 kWh once you’ve bought 350 kWh that month. Splitting your purchases doesn’t change this: the blocks count every unit you buy in the month, however you buy them.
