The interest rate does affect aggregate demand. As the interest rate falls, aggregate demand increases and vice-versa.
the aggregate demand and aggregate supply curves.
An increase in the nation's money supply lowers interest rates, thus decreases the cost of doing business. With a higher return on investment, investment spending increases and so too does aggregate supply. As aggregate supply increases, aggregate demand increases and so prices go up. Thus real GDP and APL increase.

Consumption, Investment, Government Expenditure and Net Exports
Total income depends on total employment which depends on effective demand which in turn depends on consumption expenditure and investment expenditure. Consumption depends on income and propensity to consume. Investment depends upon the marginal efficiency of capital and the rate of interest. J. M. Keynes made it clear that the level of employment depends on aggregate demand and aggregate supply. The equilibrium level of income or output depends on the relationship between the aggregate demand curve and aggregate supply curve. As Keynes was interested in the immediate problems of the short run, he ignored the aggregate supply function and focused on aggregate demand. And he attributed unemployment to deficiency in aggregate demand.
Because a tax increase will cause consumption to decrease, an aggregate demand has a greater effect.
Policies designed to affect aggregate demand: fiscal policy and monetary policy.
An increase or decrease in consumption, investment, government expenditure or net exports
When aggregate demand and aggregate supply both decrease, the result is no change to price. As price increases, aggregate demand decreases, and aggregate supply increases.
