Giving is first a matter of the heart, not a formula. Scripture points to cheerful, proportional generosity more than a single fixed number. Still, it helps to see what a percentage actually looks like. Set your monthly income and the share you want to give, and the calculator shows it by the month, by the year, and over time.
The calculator takes your monthly income and multiplies it by the percentage you choose. That gives your monthly gift. It then shows the same figure annually and adds it up across the number of years you set, so you can see the long arc of steady generosity.
A tithe traditionally means a tenth, which is why the slider starts at 10 percent. Many Christians treat that as a starting point rather than a ceiling, and others give a different proportion as they are able. Use whatever number reflects your own conviction and season.
Sincere believers land in different places. Some give on gross income as a first fruits gesture, others on take home pay. The Bible does not settle the question, so decide prayerfully and be consistent.
Faithful people disagree. The tithe is rooted in the Old Testament, while the New Testament emphasizes cheerful, proportional, sacrificial giving over a fixed percentage. The heart behind the gift matters more than the exact number.
Many people do, often at a smaller percentage, and increase it as the debt shrinks. Giving and getting out of debt are not enemies. The discipline of generosity tends to strengthen the discipline of stewardship.
