> The private savings calculator works out private (household and business) saving in the national accounts – income minus taxes, plus transfers, minus consumption – along with public saving and national saving.

## Inputs

- National income (Y)
- Taxes (T)
- Transfer payments (TR)
- Consumption (C)
- Government purchases (G)

## Results

- Private saving
- Public saving
- National saving
- National saving rate

## Formula

```
Private saving = Y − T + TR − C
Public saving = T − G − TR
National saving = private + public = Y − C − G
```

## Explanation

In a closed economy national saving equals investment. A government deficit (negative public saving) must be financed by private saving or borrowing from abroad.

### How to use the Private Savings Calculator

- **National income (Y)**
- **Taxes (T)**
- **Transfer payments (TR)**
- **Consumption (C)**
- **Government purchases (G)**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter national income (GDP), taxes, transfer payments, consumption and government purchases.

### Tips

- Use real (inflation-adjusted) figures to compare across years.
- Check whether data are seasonally adjusted.
- Use the same currency and base year throughout.
- Economic models simplify reality – treat results as illustrations, not forecasts.

### Common mistakes to avoid

- Mixing nominal and real values.
- Comparing percentage changes with percentage-point changes.
- Treating correlations as causes.

### What each result means

- **Private saving** = [National income (Y)] - [Taxes (T)] + [Transfer payments (TR)] - [Consumption (C)]
- **Public saving** = [Taxes (T)] - [Government purchases (G)] - [Transfer payments (TR)]
- **National saving** = [National income (Y)] - [Consumption (C)] - [Government purchases (G)]
- **National saving rate** = [National saving]÷[National income (Y)]×100

### Example values

How the main result changes when **National income** changes and everything else stays at the example values above:

## Worked example

Inputs — National income (Y): $24,000; Taxes (T): $5,000; Transfer payments (TR): $3,500; Consumption (C): $16,500; Government purchases (G): $4,200.

Results — **Private saving = $6,000.00**; Public saving = $-2,700.00; National saving = $3,300.00; National saving rate = 13.75 %.
