What can this calculator tell you?
Use the cash-per-second value you can actually see in your Fake an Egg session. This calculator projects earnings at a constant rate and compares two timed trips along the same route. It does not fetch live pet stats or predict whether another player will catch you.
Leave unknown fields blank. A mutation or fuse multiplier is an optional assumption you supply, not a verified game preset. If the displayed income already includes a boost, leave the multiplier at 1 to avoid counting it twice.
Use observations from your own session. There are no verified pet, mutation, fuse, weight or treadmill presets in this calculator. Leave unknown values blank. A multiplier of 1 keeps your measured rate as-is.

Calculation method and limits
Income = observed $/s × your effective multiplier. Earnings = income × minutes × 60. Break-even seconds = cost ÷ income. Do not apply a boost again if it is already included in your observed rate.
Travel-time increase = (loaded seconds ÷ unloaded seconds − 1) × 100%. Same-route speed loss = (1 − unloaded seconds ÷ loaded seconds) × 100%, relative to unloaded speed. Both require equal route distance and otherwise comparable conditions. Negative values mean the loaded run was faster; they can reflect timing noise or changed conditions.
Results are rounded to eight significant digits. Nonzero inputs must be at least 0.000000001. This is session arithmetic, not a prediction of escape success or a verified weight-to-speed formula.
Inputs stay in the URL. Share only observations you want others to see.
How are earnings and slowdown calculated?
Projected cash per second equals your entered base rate multiplied by your entered multiplier. Projected earnings equal that rate multiplied by minutes and 60. Payback time equals the entered cost divided by the projected rate; it excludes losses, downtime and changing boosts.
Time the same start and finish without a carried egg, then with it, keeping upgrades and route unchanged. Measured speed loss is 100 × (1 − unloaded seconds ÷ loaded seconds). The denominator is loaded trip time. Travel-time increase is 100 × (loaded seconds ÷ unloaded seconds − 1), using unloaded time as its denominator. These are different comparisons.
A single trip can include turns, lag or interruptions. Repeat your measurement before treating a difference as a carrying effect. No weight-to-speed or treadmill-level formula has been verified for this tool.
