The ratio of change in saving to change in income is called the marginal propensity to save

Detailed answer

Propensity to save is defined as the total income or the total increase in the income that the person saved, rather than the amount they spend on any goods.

• The marginal propensity to save is equal to the ratio of a change in saving to a change in income to the total change in the person's income or the total amount he saved.
• The average propensity is nothing but the total ratio of saving to the total income generated by that person.
