PIGGY WHAT-IF LAB

A little price change.
A clearer plan.

What if fuel goes up? Coffee gets pricier? Your electricity rate changes? Try the numbers before they surprise your budget.

Your scenario

Starts with a hypothetical example. Replace it with your own comparable costs. No live price feed or receipt upload.

For fuel, use tax-inclusive pump prices and one fuel grade. For electricity, this models the variable unit charge only—not fixed charges or tiered tariffs. Quantities and frequency stay constant in this comparison. Changing the currency or unit label does not convert amounts; enter values in that currency and unit.

Scenario

Annualization: 52 weeks, 12 months, or 365 days. Monthly amounts are annual totals ÷ 12; weekly equivalents are annual totals ÷ 52. A school-year routine may not run all year. These are estimates, not guaranteed prices, complete spending or confirmed savings.
