What a lawn really uses, and what you would save.

Published 1 July 2026

A natural lawn quietly runs up a bill every year in water, mowing and upkeep, and a carbon footprint to match. Enter your lawn size below to see what it costs, and what premium artificial grass saves over its life. Every figure is adjustable and sourced.

These are ongoing operational savings only — water, upkeep and the carbon avoided by not mowing, fertilising or watering. They do not include the upfront cost of installing artificial grass, or the turf's manufacturing carbon, which are separate.

The lawn bill nobody adds up

A natural lawn looks free once it's in. It isn't.

In Singapore's climate, keeping real grass green means watering it hard, week after week, all year. A maintained lawn drinks on the order of a thousand litres per square metre a year, and every litre is metered at the PUB rate. Add the mowing, the fertiliser, the weeding and the labour, and a modest garden quietly costs hundreds of dollars a year just to stay presentable.

Artificial grass takes almost all of that off the table. No watering, no mowing, no fertiliser, no patchy brown seasons. The calculator above turns that into a number for your exact lawn size, spread across the turf's life.

The carbon side of the same coin

Lawn care has a footprint most people never picture: petrol for the mower, the energy behind fertiliser, and the pumping and treatment of all that irrigation water. Published lawn-care studies put the operational emissions at roughly 0.4 kg of CO&sub2; per square metre each year. Artificial grass has effectively none of these ongoing emissions, so every year it stays down is carbon avoided, the same way a stand of trees quietly absorbs it.

That's the "trees" and "car kilometres" figures in the calculator: everyday equivalents for the operational carbon you stop emitting once the mower goes in the shed for good.

Why premium is the number that lasts

These savings only hold if the turf holds. Cheap grass fades and flattens within a few years, so you pay to remove and replace it, and the savings clock resets. Premium Namgrass is built to stay lush for 15–20 years with light care, which is exactly why the "over its life" figures above are worth banking on. It's the difference between a saving you calculate once and a saving you actually keep.

Common questions

How much water does artificial grass save in Singapore?

A maintained natural lawn is typically watered to roughly 1,000 litres per square metre per year. Artificial grass needs none of that, so a 100 sqm lawn saves on the order of 100,000 litres a year, plus the PUB water cost that comes with it.

Does artificial grass really cut carbon?

It removes the operational carbon of lawn care, the fuel for mowing, the fertiliser and the energy for irrigation, which is commonly estimated around 0.4 kg CO2 per square metre per year. It does not include the turf's manufacturing carbon, which is separate.

Are these savings after the cost of installing artificial grass?

No. The calculator shows ongoing operational savings only, water, upkeep and avoided lawn-care carbon. It does not deduct the upfront supply-and-install cost, which is quoted separately for your space.

Do the savings continue every year?

Yes. Water, upkeep and avoided lawn-care carbon are saved every year the turf is down, so over a premium lawn's 15 to 20 year life the totals keep compounding, which is why the "over its life" figures are the ones worth banking on.
