Booked your car? Keep an eye on the price.

Car rental prices can drop after you book. RateRewind helps you make the most of that opportunity: We monitor your existing booking and email you when we find a cheaper offer with comparable terms.

Keep your travel plans and decide for yourself whether rebooking is worthwhile.

A rental car booking is monitored and returns as a cheaper offer

What RateRewind is

Forward your booking confirmation to your personal RateRewind address or enter the details yourself. We regularly check offers for your cancellable car rental until pickup. Alongside the price, we compare vehicle class, insurance, mileage allowance and payment terms.

What RateRewind stands for

Booking your rental car lets you plan ahead. RateRewind helps you spot opportunities to save along the way. We keep an eye on prices and compare the terms that matter, giving you the information you need to decide whether to rebook. You can look forward to your trip without repeatedly searching for cheaper offers yourself.

How we earn money

The Free plan costs nothing. If you rebook for less through a clearly disclosed offer link, RateRewind may receive a commission. This does not increase the price charged by the booking provider.

You decide whether to rebook

Our email points you to a cheaper offer. Before rebooking, check the current terms and the cancellation deadline for your existing booking. Secure the new offer first, then cancel the old booking. RateRewind does not book or cancel automatically on your behalf.
