That depends on the type of bulbs you replace, the type of replacement light bulb, how long you typically use a light bulb, and what the cost of electricity is in your country. Here is a sample calculation:

Previously we normally used 100 Watt incandescent light bulbs. A 40 Watt fluorescent light bulb shines about as bright. That's a saving of 60 Watts or 0.06 kilowatts, equivalent to 0.06 kWh/hour.

If we use the light bulb 6 hours a day, 30 days a month, that's 180 hours a month. Multiply that by the savings rate, and you get an energy saving of 10.8 kWh per month. At the costs of the light bulbs we use, and of electricity, we recover the cost of the light bulb in 1-2 months - and the light bulb typically lasts much longer than that. However, you should look how much YOU pay for electricity - just look at the bill from your power company. You should also check for how much you can get a light bulb in your country - and adjust the estimate according to how much artificial light you use per day.
